Hilary Putnam first published the consistency objection against Ludwig Wittgenstein’s account of mathematics in 1979. In 1983, Putnam and Benacerraf raised this objection against all conventionalist accounts of mathematics. I discuss the 1979 version and the scenario argument, which supports the key premise of the objection. The wide applicability of this objection is not apparent; I thus raise it against an imaginary axiomatic theory T similar to Peano arithmetic in all relevant aspects. I argue that (...) a conventionalist can explain the consistency of T and suggest that an analogous explanation can be provided for the consistency of Peano arithmetic. (shrink)

Since antiquity, philosophers have struggled to describe the instant of change in continuous time in a way that is both consistent with classical logic and also objective rather than arbitrary. A particularly important version of this problem arises, I argue, for substantial change, that is, any case in which a metaphysical substance comes into or goes out of existence. I then offer and defend an analysis of the instant of substantial change in continuous time that is consistent with classical logic (...) and objective rather than arbitrary. My key assumption is that, necessarily, every substance ages at every instant at which it exists, from which I conclude that no substance has a first or a last instant of its existence if time is continuous. I also suggest that my solution offers some support for endurantism about substances. (shrink)

This paper is a critical analysis of Putnam’s “consistency objection,” an objection made against a particular reading of Wittgenstein’s philosophy of mathematics (“up-to-us-ism”). I show that Putnam’s objection presupposes a rather unlikely version of Wittgenstein’s “up-to-us-ism” and is unable to undermine a more likely anti-Platonist version. I also show that a companion argument, (the “something more” argument) is unable to overturn this more sophisticated anti-Platonist version of Wittgenstein’s up-to-us-ism. Along the way I try to clarify Wittgenstein’s (...) anti-Plalonist account of mathematics, so that others do not repeat Putnam’s mistake. (shrink)

Wittgenstein's views on mathematics are radically original. He criticizes most of the traditional philosophies of mathematics. His views have been subject to harsh criticisms. In this dissertation, I attempt to defend Wittgenstein's philosophy of mathematics from two objections: the objectivity objection and the consistency objection. The first claims that Wittgenstein's account of mathematics is not sufficient for the objectivity of mathematics; the second claims that it is only a partial account of mathematics because it cannot explain the (...) semantic properties of mathematical systems. ;The first chapter outlines Wittgenstein's Philosophy of Mathematics by stressing the differences and similarities with more traditional accounts. The second chapter discusses the objectivity objection. I distinguish epistemic from non-epistemic objectivity and discuss their relation with the issue of realism and anti-realism. I conclude first that either notion of objectivity is insufficient for disparaging anti-realist accounts of mathematics and, second, that Wittgenstein's account is sufficient for both. The third chapter is a detailed discussion of the consistency objection. Some unsuccessful replies are discussed. In the fourth chapter, I reformulate the objection by means of a rather simple axiomatic system that I call theory T. This allows us to see more clearly why the replies considered before are not successful and, furthermore, which view Wittgenstein is actually required to hold in order to reject the objection. In the fifth chapter, I offer a brief outline of Wittgenstein's account of logic and, finally, show how it provides the required answer to the consistency objection. (shrink)

Imagine a sculptor who molds a lump of clay to create a statue. Hylomorphism claims that the statue and the lump of clay are two different colocated objects that have different forms, even though they share the same matter. Recently, there has been some discussion on the requirements of consistency for hylomorphist theories. In this paper, we focus on an argument presented by Maegan Fairchild, according to which a minimal version of hylomorphism is inconsistent. We argue that the argument (...) is unsound or, at best, it just points to a well-known problem for hylmorphist theories. Additionally, we explore some general consequences of this fact. (shrink)

In this paper, I consider two curious subsystems ofFrege's Grundgesetze der Arithmetik: Richard Heck's predicative fragment H, consisting of schema V together with predicative second-order comprehension (in a language containing a syntactical abstraction operator), and a theory T in monadic second-order logic, consisting of axiom V and 1 1-comprehension (in a language containing anabstraction function). I provide a consistency proof for the latter theory, thereby refuting a version of a conjecture by Heck. It is shown that both Heck and (...) T prove the existence of infinitely many non-logical objects (T deriving,moreover, the nonexistence of the value-range concept). Some implications concerning the interpretation of Frege's proof of referentiality and the possibility of classifying any of these subsystems as logicist are discussed. Finally, I explore the relation of T toCantor's theorem which is somewhat surprising. (shrink)

This paper addresses a data integration problem: given several mutually consistent datasets each of which measures a subset of the variables of interest, how can one construct a probabilistic model that fits the data and gives reasonable answers to questions which are under-determined by the data? Here we show how to obtain a Bayesian network model which represents the unique probability function that agrees with the probability distributions measured by the datasets and otherwise has maximum entropy. We provide a general (...) algorithm, OBN-cDS, which offers substantial efficiency savings over the standard brute-force approach to determining the maximum entropy probability function. Furthermore, we develop modifications to the general algorithm which enable further efficiency savings but which are only applicable in particular situations. We show that there are circumstances in which one can obtain the model directly from the data; by solving algebraic problems; and by solving relatively simple independent optimisation problems.

This paper addresses the problem of finding a Bayesian net representation of the probability function that agrees with the distributions of multiple consistent datasets and otherwise has maximum entropy. We give a general algorithm which is significantly more efficient than the standard brute-force approach. Furthermore, we show that in a wide range of cases such a Bayesian net can be obtained without solving any optimisation problem.

It is generally accepted that the development of the modern sciences is rooted in experiment. Yet for a long time, experimentation did not occupy a prominent role, neither in philosophy nor in history of science. With the ‘practical turn’ in studying the sciences and their history, this has begun to change. This paper is concerned with systems and cultures of experimentation and the consistencies that are generated within such systems and cultures. The first part of the paper exposes the forms (...) of historical and structural coherence that characterize the experimental exploration of epistemic objects. In the second part, a particular experimental culture in the life sciences is briefly described as an example. A survey will be given of what it means and what it takes to analyze biological functions in the test tube. (shrink)

This essay offers an account of the truth conditions of sentences involving deontic modals like ‘ought’, designed to capture the difference between objective and subjective kinds of ‘ought’ This account resembles the classical semantics for deontic logic: according to this account, these truths conditions involve a function from the world of evaluation to a domain of worlds (equivalent to a so-called “modal base”), and an ordering of the worlds in such domains; this ordering of the worlds itself arises from two (...) further elements – a probability function and a value function – since this ordering ranks the worlds in accordance with the expected value of certain propositions that are true at those worlds. Thus, a proposition of the form ‘Ought (p)’ is true at a world of evaluation w if and only if p is true at all the top-ranked worlds in the domain assigned to w. This domain of worlds consists of metaphysically possible worlds, while the probability function is defined over a space of epistemically possible worlds (which may include metaphysically impossible worlds, such as worlds where Hesperus is not Phosphorus). Evidence is given that this account assigns the correct truth conditions to a wide range of sentences involving ‘ought’. Since these truth conditions involve both a domain of metaphysically possible worlds and a space of epistemically possible worlds, there are two corresponding kinds of conditional involving ‘ought’, depending on which space of worlds is restricted by the conditional. Finally, some objections that might be raised against this account are answered. (shrink)

Legal positivism’s multi-faceted insistence on the separability of law and morality includes an insistence on the thoroughly conventional status of legal norms as legal norms. Yet the positivist affirmation of the conventionality of law may initially seem at odds with the mind-independence of the existence and contents and implications of legal norms. Mind-independence, a central aspect of legal objectivity, has been seen by some theorists as incompatible with the mind-dependence of conventions. Such a perception of incompatibility has led some anti-positivist (...) theorists to reject the notion of law’s conventionality, and has led some positivist theorists to query law’s mind-independence. What will be contended here is that both camps are mistaken. (shrink)

Objective—To determine the objectivity, consistency and professional unanimity in the initiation, continuation and withdrawal of life-prolonging procedures in intensive care–to determine methods, time-scale for withdrawal and communication with both staff and relatives–to explore any professional unease about legality, morality or professional defensibility.Design—A structured questionnaire directed at clinical nurse managers for intensive care.Setting—All intensive care units in the Yorkshire region.Results—The survey reported a lack of consistency and objectivity in decision making in this area, with accompanying unease amongst staff.Conclusions—There is (...) a need to work towards more consistent care, both before and during admission, for the protection of the individual patient and to allow rational assessment of intensive care need. Comprehensive audit should lead to objective defensible decisions and facilitate informed choice. More open debate and better communication should minimise this issue as a source of stress amongst staff in intensive care. (shrink)

After a brief survey of the different meanings of consistency, the study is restricted to consistency understood as non-contradiction of sets of sentences. The philosophical reasons for this requirement are discussed, both in relation to the problem of sense and the problem of truth. The issue of mathematical truth is then addressed, and the different conceptions of it are put in relation with consistency. The formal treatment of consistency and truth in mathematical logic is then considered, (...) with particular attention paid to the relation between syntactic and semantic properties of sets and calculi. After the crisis of mathematical intuition and the dominance of the formalistic view, it seemed that consistency could totally replace the requirement of truth in mathematics, also in the sense that the existence of "objects" of axiomatic systems could be granted by their consistency. A rejection of this claim is presented, whose central point is a detailed analysis of the theorem that any consistent set S of sentences of first order logic has a model. A critical scrutiny shows that this model is very peculiar, being offered by the elements of the same language that is being interpreted, and the satisfiability conditions for any sentence being constituted by the mere fact of belonging to S. Though not being insignificant from a metatheoretical point of view, this theorem fails to endow consistency with an "ontological creativity", that is, with the capability of providing a model ontologically distinct from the language itself. A final discussion regarding the different "ontological regions" and the referential nature of truth clarifies the different aspects of the whole issue discussed. (shrink)

This paper attempts to address the question what logical strength theories of truth have by considering such questions as: If you take a theory T and add a theory of truth to it, how strong is the resulting theory, as compared to T? Once the question has been properly formulated, the answer turns out to be about as elegant as one could want: Adding a theory of truth to a finitely axiomatized theory T is more or less equivalent to a (...) kind of abstract consistency statement. A large part of the interest of the paper lies in the way syntactic theories are 'disentangled' from object theories. (shrink)

Are there nonexistent objects, i.e., objects that do not exist? Some examples often cited are: Zeus, Pegasus, Sherlock Holmes, Vulcan (the hypothetical planet postulated by the 19th century astronomer Le Verrier), the perpetual motion machine, the golden mountain, the fountain of youth, the round square, etc. Some important philosophers have thought that the very concept of a nonexistent object is contradictory (Hume) or logically ill-formed (Kant, Frege), while others (Leibniz, Meinong, the Russell of Principles of Mathematics) have embraced it wholeheartedly. (...) This entry is an examination of the many questions which arise in connection with the view that there are nonexistent objects. The following are particularly salient: What reasons are there (if any) for thinking that there are nonexistent objects? If there are nonexistent objects, then what kind of objects are they? How can they be characterized? Is it possible to provide a consistent theory of nonexistent objects? What is the explanatory force of a consistent theory of nonexistent objects (if such a thing is possible)? (shrink)

The concept of totalitarianism was particularly prevalent in intellectual and political debate in Germany in the 1970s, and was motivated largely by anti-totalitarian convictions. Although it did not enter everyday language, it persists in political rhetoric, where it is used today as a political football in speeches and constitutional reports. In response to historical approaches to the concept of totalitarianism, which generally contextualise the term and put forward alternative terms, this article probes the meaning of this term as it is (...) actually used and misused in political and educational contexts in contemporary Germany. It concludes by highlighting the fictitious (figurative, semantic and epistemological) dimensions of the rhetoric of anti-totalitarianism, and calls for a more genuinely liberal, non-totalitarian, posture.

“Evidence” in the form of data collected and analysis thereof is fundamental to medicine, health and science. In this paper, we discuss the “evidence-based” aspect of evidence-based medicine in terms of statistical inference, acknowledging that this latter field of statistical inference often also goes by various near-synonymous names—such as inductive inference (amongst philosophers), econometrics (amongst economists), machine learning (amongst computer scientists) and, in more recent times, data mining (in some circles). Three central issues to this discussion of “evidence-based” are (i) (...) whether or not the statistical analysis can and/or should be objective and/or whether or not (subjective) prior knowledge can and/or should be incorporated, (ii) whether or not the analysis should be invariant to the framing of the problem (e.g. does it matter whether we analyse the ratio of proportions of morbidity to non-morbidity rather than simply the proportion of morbidity?), and (iii) whether or not, as we get more and more data, our analysis should be able to converge arbitrarily closely to the process which is generating our observed data. For many problems of data analysis, it would appear that desiderata (ii) and (iii) above require us to invoke at least some form of subjective (Bayesian) prior knowledge. This sits uncomfortably with the understandable but perhaps impossible desire of many medical publications that at least all the statistical hypothesis testing has to be classical non-Bayesian—i.e. it is not permitted to use any (subjective) prior knowledge.

Human cognitive acts are directed towards entities of a wide range of different types. What follows is a new proposal for bringing order into this typological clutter. A categorial scheme for the objects of human cognition should be (1) critical and realistic. Cognitive subjects are liable to error, even to systematic error of the sort that is manifested by believers in the Pantheon of Olympian gods. Thus not all putative object-directed acts should be recognized as having objects of their own. (...) Broadly, the objects towards which human cognition is directed should be parts of reality in a sense that is at least consistent with the truths of natural science. But such a scheme should also be (2) comprehensive: it should do justice to each sort of object on its own terms, and not attempt to eliminate objects of one sort in favour of objects of other, more favoured sorts. Linguistic and other forms of idealism, as well as Meinongian theories, which assign to each and every referring expression or intentional act an object tailored to fit, yield categorial schemes which fail to satisfy (1). Physicalistic and other forms of reductionism yield categorial schemes which fail to satisfy (2). What follows is a categorial scheme that is both critically realistic and comprehensive. Thus it enjoys some of the benefits of linguistic idealism and physicalism, without (or so it is hoped) the corresponding disadvantages of each. (shrink)

Defenders of medical professionals’ rights to conscientious objection (CO) regarding emergency contraception (EC) draw an analogy to CO in the military. Such professionals object to EC since it has the possibility of harming zygotic life, yet if we accept this analogy and utilize jurisprudence to frame the associated public policy, those who refuse to dispense EC would not have their objection honored. Legal precedent holds that one must consistently object to all forms of the relevant activity. In the (...) case at hand, then, I argue that these professionals must also oppose morally innocuous practices that may prevent pregnancy after fertilization. These results reveal that such objectors cannot offer a plausible and consistent objection to harming zygotic life. Additionally, there are good reasons to reject the analogy itself. In either case, these findings call into question the case supporting refusals of EC based on scruples. (shrink)

What does the passage of time consist in? There are some suggestive metaphors. âEvents approach us, pass us, and recede from us, like sticks and leaves floating on the river of time.â âWe are moving from the past into the future, like ships sailing into an unknown ocean.â There is surely something right and deep about these metaphors. But how close are they to the literal truth? In this book Bradford Skow argues that they are far from the literal truth. (...) Skowâs argument takes the form of a defense of the block universe theory of time, a theory that, in many ways, treats time as a dimension of reality that closely resembles the three dimensions of space. Opposed to the block universe theory of time are theories that take the metaphors more seriously: presentism, the moving spotlight theory, the growing block theory, and the branching time theory. These are theories of ârobustâ passage of time, or âobjective becoming.â Skow argues that the best of these theories, the block universe theoryâs most worthy opponent, is the moving spotlight theory, the theory that says that âpresentnessâ moves along the series of times from the past into the future. Skow defends the moving spotlight theory against the objection that it is inconsistent, and the objection that it cannot answer the question of how fast time passes. He also defends it against the objection that it is incompatible with Einsteinâs theory of relativity. Skow proposes several ways in which the moving spotlight theory may be made compatible with the theory of relativity. Still, this book is ultimately a defense of the block universe theory, not of the moving spotlight theory. Skow holds that the best arguments against the block universe theory, and for the moving spotlight theory, start from the idea that, somehow, the passage of time is given to us in experience. Skow discusses several different arguments that start from this idea, and argues that they all fail. (shrink)

John Doris has recently argued that since we do not possess character traits as traditionally conceived, virtue ethics is rooted in a false empirical presupposition. Gopal Sreenivasan has claimed, in a paper in Mind, that Doris has not provided suitable evidence for his empirical claim. But the experiment Sreenivasan focuses on is not one that Doris employs, and neither is it relevantly similar in structure. The confusion arises because both authors use the phrase ‘cross-situational consistency’ to describe the aspect (...) of character traits that they are concerned with, but neither defines this phrase, and it is ambiguous: Doris uses it in one sense, Sreenivasan in another. Partly for this reason, the objections Sreenivasan raises fail to block the argument Doris provides. In particular, the most reliable data Doris employs, Milgram’s famous study of authority, is entirely immune to Sreenivasan’s objections. Sreenivasan has not shown, therefore, that Doris provides unsuitable evidence for his claim. (shrink)

Conscientious objection in health care is a form of compromise whereby health care practitioners can refuse to take part in safe, legal, and beneficial medical procedures to which they have a moral opposition (for instance abortion). Arguments in defense of conscientious objection in medicine are usually based on the value of respect for the moral integrity of practitioners. I will show that philosophical arguments in defense of conscientious objection based on respect for such moral integrity are extremely (...) weak and, if taken seriously, lead to consequences that we would not (and should not) accept. I then propose that the best philosophical argument that defenders of conscientious objection in medicine can consistently deploy is one that appeals to (some form of) either moral relativism or subjectivism. I suggest that, unless either moral relativism or subjectivism is a valid theory—which is exactly what many defenders of conscientious objection (as well as many others) do not think—the role of moral integrity and conscientious objection in health care should be significantly downplayed and left out of the range of ethically relevant considerations.

The consistent histories reformulation of quantum mechanics was developed by Robert Griffiths, given a formal logical systematization by Roland Omn\`{e}s, and under the label `decoherent histories', was independently developed by Murray Gell-Mann and James Hartle and extended to quantum cosmology. Criticisms of CH involve issues of meaning, truth, objectivity, and coherence, a mixture of philosophy and physics. We will briefly consider the original formulation of CH and some basic objections. The reply to these objections, like the objections themselves, involves a (...) mixture of physics and philosophy. These replies support an evaluation of the CH formulation as a replacement for the measurement, or orthodox, interpretation. (shrink)

Despite the skepticism of many mathematicians and logicians as to the possibility of any test which will show conclusively the consistency or independence of the members of a postulate set, several methods have nevertheless been devised and employed, e.g., the empirical methods of Russell and Huntington, the internal method of Hilbert, and the reflective method of Royce. However, with the possible exception of Hilbert's method, these techniques require us to forsake the purely formal or abstract mode of analysis, and (...) instead to rely in some sense on “concrete representations” or “interpretations” or “modes of action” which are said to “satisfy” the postulates in question. In short, they are all interpretational methods—and here is the crux of the problem. “Is it possible,” queries Weiss, “that the only way we can determine whether a set is consistent is by seeing all the postulates actually exemplified in some object? If so, we must arbitrarily assume that the object is self-consistent, so that the proof of consistency must ultimately rest on a dogma. As independence rests on consistency there are therefore no satisfactory proofs as yet of either independence or consistency.” The question “is thus answered,” according to Young, “only by reference to a concrete representation of the abstract ideas involved, and it is such concrete representations that we wished especially to avoid. At the present time, however, no absolute test for consistency is known.” Moreover, “suppose,” says the late Dr. Eaton, “that the system has no interpretation: how can the consistency independence … of the postulates be shown? There should be some analytic way—purely in the realm of the abstract, without interpretation—of establishing these properties of a set of postulates. This is an important problem that awaits solution.”. (shrink)

This essay consists of two parts. In the first part, I focus my attention on the remarks that Frege makes on consistency when he sets about criticizing the method of creating new numbers through definition or abstraction. This gives me the opportunity to comment also a little on H. Hankel, J. Thomae—Frege’s main targets when he comes to criticize “formal theories of arithmetic” in Die Grundlagen der Arithmetik (1884) and the second volume of Grundgesetze der Arithmetik (1903)—G. Cantor, L. (...) E. J. Brouwer and D. Hilbert (1899). Part 2 is mainly devoted to Hilbert’s proof theory of the 1920s (1922–1931). I begin with an account of his early attempt to prove directly, and thus not by reduction or by constructing a model, the consistency of (a fragment of) arithmetic. In subsequent sections, I give a kind of overview of Hilbert’s metamathematics of the 1920s and try to shed light on a number of difficulties to which it gives rise. One serious difficulty that I discuss is the fact, widely ignored in the pertinent literature on Hilbert’s programme, that his language of finitist metamathematics fails to supply the conceptual resources for formulating a consistency statement qua unbounded quantification. Along the way, I shall comment on W. W. Tait’s objection to an interpretation of Hilbert’s finitism by Niebergall and Schirn, on G. Gentzen’s allegedly finitist consistency proof for Peano Arithmetic as well as his ideas on the provability and unprovability of initial cases of transfinite induction in pure number theory. Another topic I deal with is what has come to be known as partial realizations of Hilbert’s programme, chiefly advocated by S. G. Simpson. Towards the end of this essay, I take a critical look at Wittgenstein’s views about (in)consistency and consistency proofs in the period 1929–1933. I argue that both his insouciant attitude towards the emergence of a contradiction in a calculus and his outright repudiation of metamathematical consistency proofs are unwarranted. In particular, I argue that Wittgenstein falls short of making a convincing case against Hilbert’s programme. I conclude with some philosophical remarks on consistency proofs and soundness and raise a question concerning the consistency of analysis. (shrink)

In this study, Consistency and Balance Model (CBM) is proposed and introduced. In the context of the model, the importance of consistency is emphasized in morality just like in Philosophy. Therefore, CBM gives the reason prominence in morality to ensure the consistency and according to CBM the emotion, the intuition and the conscience in addition to the reason, are also important. In order to see the principles determined by the reason in human behaviors, two kinds of classification (...) are developed for the virtues that is defined as the middle of excess and defect. The first of them is the triple classification of virtues that draws attention to the false existence of virtues and determines the opposite of virtues as forming dichotomy. The latter is the tetrad classification, which is based on the duality of two means that propose to consider the virtues together. The Contrast is considered as the central concept in the first classification and the integration is considered as the central concept in the second classification. Then it is offered that the virtues may be evaluated consistently in the social, global and theological contexts. However, the ideal morality with objective qualities and the real morality with subjective qualities are produced in order to reach the universal morality that is determined by the reason, then the consistency and the integration are proposed for them. Similarly, consistency and integration are proposed in the dualities of principle-virtue, abstract-concrete, intention-outcome, universality-locality, objectivity-subjectivity throughout the study. Finally, it is pointed out that the reasonableness of applying consistency in morality has exceptions.Summary: Philosophy is the logical, systematic and consistent thinking that focuses on specific questions and topics to reach the reality. When this basic tendency of philosophy is applied to morality, logical, systematic and consistent actions are expected to emerge. Accordingly, a new model called as Consistency and Balance Model (CBM) is proposed and introduced in this article. By this model, the importance of consistency is emphasized in morality just like in philosophy. Therefore, CBM gives the reason prominence in morality to ensure thought, expression and behavior consistency. According to CBM the human emotion, the divine intuition and the solid conscience in addition to reason are required to determine the virtues. CBM, which is a synthesis of the good intention and the reason, aims to constitute the sensible and good actions. According to CBM, which has a holistic structure, if a person can adopt the virtue as a principle and reflect the virtue in all of his behaviors during his whole life, he can be defined as consistently virtuous.CBM defines the good with the concepts of consistency and balance. According to CBM, the good is the mean of excess and defect. In this respect, CBM is based on Aristotle’s mean idea. However, CBM aims to develop it with new content. Two important questions arise during the identification of the evil: 1. Is it bad that nothing happens? 2. Is it bad that something is wrong? The point of defect represents the absence and the point of excess represents the fallacy in the entity. Both of them are bad in morality. The middle of them is the virtue. In order to see the principles determined by the reason in human behaviors, two kinds of classification are developed for the virtues which are defined as the middle of excess and defect. The first is the triple classification of virtues that draws attention to the false existence of virtues and determines the opposite of virtues as forming dichotomy. The triple classification, which forms a dichotomy as an empty pattern that can be applied to all virtues, is determined as over virtue-virtous-virtueless. According to CBM the opposite of the mean is always clearly the point of defect and implicitly the point of excess. Therefore, it is important to determine extremes of virtues. The point of defect can be briefly denoted as virtueless. The point of excess can be denoted as in fact virtueless, pretending as virtuous, masked virtue and over virtue. The latter is the tetrad classification, which is based on the duality of two means. In this classification, it is possible to produce new and better virtues by considering two virtues together. The Contrast is considered as the central concept in the first classification and the integration is considered as the central concept in the second classification.The principle is seen as a guarantee for the consistency in philosophy. CBM points out that a similar situation should be in ethics. According to Kant, the invisible internal principles of the actions are more important than the actions themselves to determine the moral value. The principle does not vary according to the individual and the condition, on the contrary, the individual is shaped by the principle and all individuals benefit equally from the outcome of the principle. Thus, the abuse of the rights of individuals with arbitrary treatments and double standards are prevented. In this democratic environment formed by the principle not only the owner of the power, but all right holders can get their rights. In this respect, the adherence to the principle is the guarantee of the rights and the freedom by establishing a balance between the rule and the freedom.Aristotle’s virtue and Kant’s principle are discussed in a holistic manner in this study. Thus, it is aimed that the principles in the human mind and the virtues in human actions are consistent in themselves and ultimately the union of the principles and the virtues can be ensured. Besides, the concepts of the ideal morality and the real morality are introduced in this article. The ideal morality takes place on the objective basis of the good and the truth, which is absolute, universally and unarguably accepted by everyone. The ideal morality with its objective qualities can be seen as the target that people know and want to achieve. The real morality is the morality that is shaped in the people or society in all its positive and negative aspects, which also includes the subjectivity of them as their own realities. The real morality with subjective qualities is the morality that occurs in life. CBM aims at the integrity and the consistency between the ideal morality and the real morality to reach the universal morality. In this article, the virtues are divided into two parts as material and spiritual. Then it is offered that the virtues may be evaluated consistently in the principal, individual, social, global and theological contexts. In this context, on the one hand it is aimed that the principal, individual, social, global and theological virtues are consistent within themselves and on the other hand they all are consistent within each other. In this classification the principal and theological morality have objective qualities and the individual and social morality have subjective qualities. CBM aims at an objectivity that incorporates subjectivity within the consistency and integrity of the principal, individual, social, global and theological morality. CBM aims to achieve the ultimate morality by integrating the starting point as the principal morality and the end point as the theological morality and to make them clear in the individual and social morality. As a result, CBM confirms the mean found by reason, by the revelation given by God. In other words, the morality that God has already there and always presents and the morality that the human mind finds here and now coincide. The consistency and integration are also proposed in the dualities of principle-virtue, abstract-concrete, intention-outcome, universality-locality, objectivity-subjectivity in the article. However, consistency, which is the central concept of the article, can form the basis for possible criticisms. But, it can be foreseen that the possible criticisms oriented to CBM would come from an extreme consistency perception that detaches the concept of consistency from reality without careful consideration. For this reason it should be kept in mind that it is wrong to expect excessive consistency in human behavior and to accept the ideal morality as absolute by neglecting the real morality. Finally, it is pointed out that the reasonableness of applying the consistency in morality has exceptions. (shrink)

Chemists do not aim at testing preconceptions or theoretical hypotheses only; they first and foremost produce and determine the object of chemical investigation: they learn through making. They never cease to create and stabilize heterogeneous devices, methods, models, and theories in order to act upon the world. Chemical bodies cannot be studied in isolation; their properties constitutively depend on what surrounds and acts upon them. Starting from the specificity of chemical practices, this paper investigates the meaning of consistency, inconsistency, (...) and that of the ceteris paribus clause, in this domain of science. In so doing, it defends the idea that studying what we call ‘a lack of consistency’ should always include the scrutiny of: the way a particular scientific practice is stabilized, and the ontological or pragmatic assumptions about the entities and processes upon which this practice revolves.

A typical guiding principle of an account of truth is: “truth is objective,” or, to be clear, judging whether an assertion is true or false depends upon how things are in the world rather than how someone or some community believes it to be. Accordingly, whenever a claim is objectively true, its truth conditions ought not depend upon the context in which it is uttered or the utterer making the claim. Part of our ongoing empirical studies surveying people’s responses to (...) questions about truth involved prompts on objectivity. Our studies suggest the following: overall, individuals tend to endorse claims that are consistent with the objectivity of truth; not all conceptions of objectivity are equal, even people who endorse the objectivity of truth sometimes assent to one form of truth’s objectivity over other forms; philosophers and non-philosophers both endorse the objectivity of truth, but the apparent commitment of philosophers is stronger.

The ability to reason about how things were made is a pervasive aspect of how humans make sense of physical objects. Such reasoning is useful for a range of everyday tasks, from assembling a piece of furniture to making a sandwich and knitting a sweater. What enables people to reason in this way even about novel objects, and how do people draw upon prior experience with an object to continually refine their understanding of how to create it? To explore these (...) questions, we developed a virtual task environment to investigate how people come up with step‐by‐step procedures for recreating block towers whose composition was not readily apparent, and analyzed how the procedures they used to build them changed across repeated attempts. Specifically, participants (N = 105) viewed 2D silhouettes of eight unique block towers in a virtual environment simulating rigid‐body physics, and aimed to reconstruct each one in less than 60 s. We found that people built each tower more accurately and quickly across repeated attempts, and that this improvement reflected both group‐level convergence upon a tiny fraction of all possible viable procedures, as well as error‐dependent updating across successive attempts by the same individual. Taken together, our study presents a scalable approach to measuring consistency and variation in how people infer solutions to physical assembly problems. (shrink)

In this article, I examine two of the standard objections to forms of value hedonism. The first is the common claim, most famously made by Bradley and Moore, that Mill's qualitative hedonism is inconsistent. The second is the apparent problem for quantitative hedonism in dealing with malicious pleasures. I argue that qualitative hedonism is consistent, even if it is implausible on other grounds. I then go on to show how our intuitions about malicious pleasure might be misleading.

Early modern empiricists thought that the nature of perceptual experience is given by citing the object presented to the mind in that experience. Hallucination and illusion suggest that this requires untenable mind-dependent objects. Current orthodoxy replaces the appeal to direct objects with the claim that perceptual experience is characterized instead by its representational content. This paper argues that the move to content is problematic, and reclaims the early modern empiricist insight as perfectly consistent, even in cases of illusion, with the (...) realist contention that these direct objects of perception are the persisting mind-independent physical objects we all know and love.

Many philosophers are convinced that rationality dictates that one’s overall set of intentions be consistent. The starting point and inspiration for our study is Bratman’s planning theory of intentions. According to this theory, one needs to appeal to the fulfilment of characteristic planning roles to justify norms that apply to our intentions. Our main objective is to demonstrate that one can be rational despite having mutually inconsistent intentions. Conversely, it is also shown that one can be irrational despite having a (...) consistent overall set of intentions. To overcome this paradox, we argue that it is essential for a successful planning system that one’s intentions are practically consistent rather than being consistent or applying an aggregation procedure. Our arguments suggest that a new type of norm is needed: whereas the consistency requirement focuses on rendering the contents of one’s intentions consistent, our new practical consistency requirement demands that one’s intentions be able to simultaneously and unconditionally guide one’s action. We observe that for intentions that conform to the ‘own-action condition’, the practical consistency requirement is equivalent to the traditional consistency requirement. This implies that the consistency requirement only needs to be amended in scenarios of choice under uncertainty. (shrink)

Objects generate time; time does not generate or change objects. That is the central thesis of this book by the philosopher Graham Harman and the archaeologist Christopher Witmore, who defend radical positions in their respective fields. Against a current and pervasive conviction that reality consists of an unceasing flux-a view associated in philosophy with New Materialism-object-oriented ontology asserts that objects of all varieties are the bedrock of reality from which time emerges. And against the narrative convictions of time as the (...) course of historical events, the objects and encounters associated with archaeology push back against the very temporal delimitations which defined the field and its objects ever since its professionalization in the nineteenth century. In a study ranging from the ruins of ancient Corinth, Mycenae, and Troy to debates over time from Aristotle and al-Ash'ari through Henri Bergson and Alfred North Whitehead, the authors draw on alternative conceptions of time as retroactive, percolating, topological, cyclical, and generational, as consisting of countercurrents or of a surface tension between objects and their own qualities. Objects Untimely invites us to reconsider the modern notion of objects as inert matter serving as a receptacle for human categories"-. (shrink)

One familiar form of argument for rejecting entities of a certain kind is that, by rejecting them, we avoid certain difficult problems associated with them. Such problem-avoidance arguments backfire if the problems cited survive the elimination of the rejected entities. In particular, we examine one way problems can survive: a question for the realist about which of a set of inconsistent statements is false may give way to an equally difficult question for the eliminativist about which of a set of (...) inconsistent statements fail to be 'factual'. Much of the first half of the paper is devoted to explaining a notion of factuality that does not imply truth but still consists in 'getting the world right'. The second half of the paper is a case study. Some 'compositional nihilists' have argued that, by rejecting composite objects (and so by denying the composition ever takes place), we avoid the notorious puzzles of coincidence, for example, the statue/lump and the ship of Theseus puzzles. Using the apparatus developed in the first half of the paper, we explore the question of whether these puzzles survive the elimination of composite objects. (shrink)

On the one hand, first-order theories are able to assert the existence of objects. For instance, ZF set theory asserts the existence of objects called the power set, while Peano Arithmetic asserts the existence of zero. On the other hand, a first-order theory may or not be consistent: it is if and only if no contradiction is a theorem. Let us ask, What is the connection between consistency and existence?

It is generally unquestioned that human subjects research review boards should assess the ethical acceptability of protocols. It says so right on the tin, after all: they are explicitly called research ethics committees in the UK. But it is precisely those sorts of unchallenged assumptions that should, from time to time, be assessed and critiqued, in case they are in fact unfounded. John Stuart Mill's objection to suppressers of dissent is instructive here: “If the opinion is right, they are (...) deprived of the opportunity of exchanging error for truth: if wrong, they lose, what is almost as great a benefit, the clearer perception and livelier impression of truth, produced by its collision with error”.1 Andrew Moore and Andrew Donnelly's compelling article, “The job of ‘ethics committees’”, is just this sort of challenge to conventional wisdom, a rejection of the notion that review boards should be considering ethical matters at all.2 If true, we should be substantially reforming our research ethics policies. And if false, rebuttals would help strengthen and ground the otherwise unquestioned assumption of the role of ethics committees. As it happens, I will argue that their critiques fall into the second category. While mistaken, they present a valuable opportunity to clarify the role of ethics committees and their relationship to relevant codes. In particular, I will defend a hybrid account where codes have strict primacy, but leave significant room for review boards …. (shrink)

This article proposes an object properties approach to object perception. By thinking about objects as clusters of co-instantiated features that possess certain canonical higher-order object properties we can steer a middle way between two extreme views that are dominant in different areas of empirical research into object perception and the development of the object concept. Object perception should be understood in terms of perceptual sensitivity to those object properties, where that perceptual sensitivity can be explained in a manner consistent with (...) the graded representation approach adopted by some connectionist modellers. The object properties approach does justice to the differences between a perceptual system solving the binding problem, on the one hand, and genuinely perceiving objects, on the other, without running into the theoretical problems associated with treating young infants as 'little scientists'.

In their insightful article, ‘The Disvalue of Death in the Global Burden of Disease’, Solberg et al argue that there is a potential incoherence in the way disability-adjusted life years are calculated. Morbidity is measured in years lived with disability in a way quite unlike the way mortality is measured in years of life lost. This potentially renders them incommensurable, like apples and oranges, and makes their aggregate—DALYs—conceptually unsound. The authors say that it is ‘vital’ to address this problem, that (...) ‘[n]eglecting [it] is not an option’, and that ‘one cannot add YLLs and YLDs together in [their] current form’.1 Though one might object to their argument in various ways, let us assume the authors are correct that there is a potential inconsistency here. I want to ask why we should be troubled by that. Now, this question may scarcely seem worth asking. Consistency and coherence are regarded as non-negotiable in so many domains that of course we should demand them in a measure such as the DALY. And this desire for coherence is clearly shared by both the architects of the DALY and their critics.2 3 I think, though, that things are more complicated. In 2012, I wrote an article discussing the epidemiological perspective from which DALYs should be calculated.4 Simplifying greatly, here is the problem: both YLDs and YLLs can be calculated either from prevalence data or from incidence data. The most natural way to calculate YLDs bases them on prevalences, because when we think about morbidity our initial thought is of people who are suffering. The most natural way to calculate YLLs bases them on an incidence measure, because when …. (shrink)

This paper is about how action and perception are related in self–awareness. The main positive claim is that bodily awareness may consist in perceptual experiences that are sufficient to provide corporeal objects with introspective self–awareness. The short–term goal is to examine the grounds and motivations for strong versions of the claim that the self–awareness of corporeal objects is dependent on the exercise of their agency. As examples of ‘patient perceivers’ show, we should not underestimate the resources that perceptual experience alone (...) offers to corporeal selves. (shrink)

Is consistency the sort of thing that could provide a guide to mathematical ontology? If so, which notion of consistency suits this purpose? Mark Balaguer holds such a view in the context of platonism, the view that mathematical objects are non-causal, non-spatiotemporal, and non-mental. For the purposes of this paper, we will examine several notions of consistency with respect to how they can provide a platon-ist epistemology of mathematics. Only a Gödelian notion, we suggest, can provide a (...) satisfactory guide to a platonist ontology. Is consistency the sort of thing that could provide a guide to mathematical ontology? If so, which notion of consistency suits this purpose? Mark Bala-guer holds such a view in the context of platonism, the view that mathematical objects are non-causal, non-spatiotemporal, and non-mental. Balaguer's version of Platonism, Full-Blooded Platonism (FBP), is the view that "there are as many abstract mathematical objects as there could be-i.e., there actually exist abstract mathematical objects of all possible kinds" (Balaguer, 2017, p. 381). He continues: Since FBP says that there are abstract mathematical objects of all possible kinds, it follows that if FBP is true, then every purely mathematical theory that could be true-i.e., that is internally consistent-accurately describes some collection of actually existing abstract objects. Thus it follows from FBP that in order to acquire knowledge of abstract objects, all we have to do is come up with an internally consistent purely mathematical theory (and know that it is internally consistent).

We all have an intuitive grasp of the concept of evidence. Evidence makes beliefs reasonable, justifies jury verdicts, and helps resolve our disagreements. Yet getting clear about what evidence is is surprisingly difficult. Among other possibilities, evidence might consist in physical objects like a candlestick found at the crime scene, propositions like ‘a candlestick was found at the crime scene,’ or experiences like the experience of witnessing a candlestick at the crime scene. This dissertation is a defense of the latter (...) view. Evidence, we will argue, consists in experiences or mental states called ‘seeming states.’ We begin with a look at why the logical positivists came to abandon the experiential or “phenomenal” conception of evidence and adopted what I call “the courtroom conception.” Despite its appeal, we argue that this latter view is too objective; it has trouble playing the role of subjective reasons-provider. Being more subjective, the phenomenal conception deserves another look. However, many have thought that the phenomenal conception itself is unable to fulfill other important roles of evidence. In chapter two we dispute this, arguing that the phenomenal conception can play all four of the chief roles of evidence. Examining the religious epistemology of Alvin Plantinga in chapter three we come to see that the phenomenal conception, while attractive, is in danger of being too subjective. If the phenomenal conception of evidence is to be tenable, it must be offered in conjunction with a conservative epistemic principle which tethers together experiences with the beliefs they evidence in an epistemically appropriate manner. Hence in chapter four we consider a number of conservative epistemic principles and argue for the superiority of one in particular. But these principles have themselves been subject to criticism. For this reason, in chapter five we close by responding to a recent and pressing challenge to conservative principles in epistemology (Michael Bergmann’s dilemma for internalism) which might prevent their deployment alongside the phenomenal conception. If our arguments are correct, the phenomenal conception of evidence is still an attractive account of evidence today. (shrink)

This monograph identifies the essential characteristics of the objects described by current quantum theory and considers their relationship to space-time. In the process, it explicates the senses in which quantum objects may be consistently considered to have parts of which they may be composed or into which they may be decomposed. The book also demonstrates the degree to which reduction is possible in quantum mechanics, showing it to be related to the objective indefiniteness of quantum properties and the strong non-local (...) correlations that can occur between the physical quantities of quantum subsystems. Careful attention is paid to the relationships among such property correlations, physical causation, probability, and symmetry in quantum theory. In this way, the text identifies and clarifies the conceptual grounds underlying the unique nature of many quantum phenomena. (shrink)

If properties are to play a useful role in semantics, it is hard to avoid assuming the naïve theory of properties: for any predicate Θ(x), there is a property such that an object o has it if and only if Θ(o). Yet this appears to lead to various paradoxes. I show that no paradoxes arise as long as the logic is weakened appropriately; the main difficulty is finding a semantics that can handle a conditional obeying reasonable laws without engendering paradox. (...) I employ a semantics which is infinite-valued, with the values only partially ordered. Can the solution be adapted to naïve set theory? Probably not, but limiting naïve comprehension in set theory is perfectly satisfactory, whereas this is not so in a property theory used for semantics. (shrink)

differentiaily rated pairwise similarity when confronted with two pairs of objects, each revolving in a separate window on a computer screen. Subject data were pooled using individually weighted MDS (ref. 11; in all the experiments, the solutions were consistent among subjects). In each trial, the subject had to select among two pairs of shapes the one consisting of the most similar shapes. The subjects were allowed to respond at will; most responded within 10 sec. Proximity (that is, perceived similarity) tables (...) derived from the judgments were processed to verify their degree of transitivity (4% of all triplets were found intransitive) and then submitted to MDS. In the long-term memory (LTM) variant of this experiment, the subjects were first trained to associate a label (a three-letter nonsensical string, such as "BON" or "POM") with each object and then carried out the pairs of pairs comparison task from memory, prompted by the object labels rather than by the objects themselves. Six subjects participated in each of the two LTM experiments (Star and Triangle). The subjects were taught each shape in a separate session and had to discriminate between that shape and six similar nontargets from various viewpoints. Training continued until the recognition rate reached 90%, over a period of several days. The subjects were never exposed to more than one target in one session and were not told the ultimate purpose of the experiment. After 2 to 3 days of rest, they were tested with questions such as: "is the BON more similar to POM than TOC to ROX?", for all pairs of pairs of stimuli. In the LTM experiments, 8% of the.. (shrink)
