Many philosophers are baffled by necessity. Humeans, in particular, are deeply disturbed by the idea of necessary laws of nature. In this paper I offer a systematic yet down to earth explanation of necessity and laws in terms of invariance. The type of invariance I employ for this purpose generalizes an invariance used in meta-logic. The main idea is that properties and relations in general have certain degrees of invariance, and some properties/relations have a stronger degree of invariance (...) than others. The degrees of invariance of highly-invariant properties are associated with high degrees of necessity of laws governing/describing these properties, and this explains the necessity of such laws both in logic and in science. This non-mysterious explanation has rich ramifications for both fields, including the formality of logic and mathematics, the apparent conflict between the contingency of science and the necessity of its laws, the difference between logical-mathematical, physical, and biological laws/principles, the abstract character of laws, the applicability of logic and mathematics to science, scientific realism, and logical-mathematical realism.

Change and necessity is a statement of Darwinian natural selection as a process driven by chance necessity, devoid of purpose or intent.

A popular response to the Exclusion Argument for physicalism maintains that mental events depend on their physical bases in such a way that the causation of a physical effect by a mental event and its physical base needn’t generate any problematic form of causal overdetermination, even if mental events are numerically distinct from and irreducible to their physical bases. This paper presents and defends a form of dualism that implements this response by using a dispositional essentialist view of properties to (...) argue that the psychophysical laws linking mental events to their physical bases are metaphysically necessary. I show the advantages of such a position over an alternative form of dualism that merely places more “modal weight” on psychophysical laws than on physical laws. The position is then defended against the objection that it is inconsistent with dualism. Lastly, some suggestions are made as to how dualists might clarify the contribution that mental causes make to their physical effects. (shrink)

The minimal God exemplifies essential omnipotence, omniscience, and moral perfection, but none of the other properties of the traditional God. I examine the consequences of the minimal God in augmented S5, S4, and Kρσ. The metaphysical consequences for the minimal God in S5 include the impossibility that God—or any other object—might acquire, lose, or exchange an essential property. It is impossible that an essentially divine being might become essentially human, for instance. The epistemological consequences include the impossibility of agnosticism—it is (...) impossible that P(◻︎FG |E) = P(~◻︎FG| E). Indeed, every weaker forms of agnosticism are also impossible—it is impossible that P(◻︎FG |E) = n, n(0 < n < 1). The metaphysical and epistemological consequences for the minimal God in S4 are equally untenable. I show that we can avoid all of these unwelcome epistemological consequences for the minimal God in Kρσ. But Kρσ has some extraordinary metaphysical consequences for the minimal God. All of the problems for the minimal God generalize to the maximal God. (shrink)

This article aims to provide an a priori argument—termed the Flourishment Argument, for the veracity of the Christian conception of the Abrahamic religion that centres on God’s action of sending a divine and atoning prophet into the world. This specific informal argument will be presented through the formulation of a set of a priori reasons for why God would seek to interact with the world—developed in light of the work of Richard Swinburne, John Finnis, Linda Zagzebski and Alexander Pruss—which, in (...) combination, will provide individuals with grounds for believing in the veracity of these important Christian teachings.

Our knowledge of natural categories includes beliefs not only about what is true of them but also about what would be true if the categories had properties other than (or in addition to) their actual ones. Evidence about these beliefs comes from three lines of research: experiments on category-based induction, on hypothetical transformations of category members, and on definitions of kind terms. The 1st part of this article examines results and theories arising from each of these research streams. The 2nd (...) part considers possible unified theories for this domain, including theories based on ideals and norms. It also contrasts 2 broad frameworks for modal category information: one focusing on beliefs about intrinsic or essential properties, the other focusing on interacting causal relations. (shrink)

Timothy Williamson’s Modal Logic as Metaphysics is a book-length defense of necessitism about objects—roughly put, the view that, necessarily, any object that exists, exists necessarily. In more formal terms, Williamson argues for the validity of necessitism for objects (NO: ◻︎∀x◻︎∃y(x=y)). NO entails both the (first-order) Barcan formula (BF: ◇∃xΦ → ∃x◇Φ, for any formula Φ) and the (first-order) converse Barcan formula (CBF: ∃x◇Φ → ◇∃xΦ, for any formula Φ). The purpose of this essay is not to assess Williamson’s arguments either (...) for necessitism (although discussion of these arguments will play a central role in the dialectic) or for necessitism’s two famous corollaries. Instead, the focus shall be a general principle governing abstract objects—the abstract of principle (or AOP) —instances of which seems to be at work in some of Williamson’s central arguments for necessitism. The AOP can be straightforwardly formulated and applied within the neo-logicist framework—in fact, arguably the principle is most naturally formulated in neo-logicist terms. -/- After closely examining, and carefully formalizing, the AOP, the remainder of the paper focuses on arguments for necessitism-like claims (the exact meaning of “necessitism-like” will become clearer as the essay progresses) based on the AOP. In particular, we shall focus on the instance of the AOP that applies to the abstract objects governed by the most well-known and most fully studied abstraction principle: Hume’s Principle (HP). It turns out that, although we cannot reconstruct a valid argument for necessitism based on this numerical instance of the AOP, we can obtain valid arguments for weaker, but equally interesting conclusions. In particular, we shall show that, although HP combined with the AOP (and some additional, related assumptions) allows the contents of the domains of possible worlds to vary, the size of those domains must remain constant. The paper concludes by developing and critiquing some related arguments for necessitism based on applying relevant instances of the AOP to abstraction principles governing sets (or extensions), and to a simple objectual abstraction principle.

According to Arnauld, if we cannot help acting in some way, that is either (1) because external forces or obstacles leave no alternative, or (2) because we cannot help wanting to act that way; and that may be (2a) because we have absolutely no power to want anything else, or (2b) because the power we have is quite insufficient to overcome the inclination to act that way. This gives three kinds of necessity, corresponding to (1), (2a) and (2b).[.

Marketing research interviewers often feel that they must compromise their own moral principles while executing work-related activities. This finding is based on analysis of data obtained from three focus group interviews and a mail survey of 173 telephone survey interviewers. Data from the mail survey were used to construct scales measuring interviewers' perceived necessity of moral compromise, moral character, and job satisfaction. The three scales then were used in a hierarchical regression analysis to predict incidences of interviewers' self-reported proscribed (...) behaviors on the job, the latter being an index of behaviors known by interviewers to be wrong. Results support all hypothesized relationships. (shrink)

‘The several modes of feeling, perception, desire, and will, so far as we are aware of them, are in general called ideas (mental representations) and it may be roughly said that philosophy puts thoughts, categories, or, in more precise language, adequate notions, in the place of generalized images we ordinarily call ideas. Mental impressions such as these may be regarded as the metaphors of thoughts and notions. But to have these figurate conceptions does not imply that we appreciate their intellectual (...) significance, the thoughts and rational notions to which they correspond. Conversely, it is one thing to have thoughts and intelligent notions, and another to know what impressions, perceptions, and feelings correspond to them’.1. (shrink)

In the Posterior Analytics (I 6, 75a18–27) Aristotle discusses a puzzle which endangers the possibility of inferring a non-necessary conclusion. His solution relies on the distinction between the necessity of the conclusion's being the case and the necessity of admitting the conclusion once one has admitted the premisses. The former is a factual necessity, whereas the latter is meant to be a normative or deontic necessity that is independent of the facts stated by the premisses and (...) the conclusion. This paper maintains that Aristotle resorts to this distinction because he thinks that, as long as it is conceived as a factual relation, logical consequence cannot exist independently of the facts expressed by the premisses and the conclusion. As a corollary, the necessity of such a consequence relation always requires the necessity of these facts. Aristotle holds this factual conception of logical consequence responsible for the puzzle, since it cannot account for valid syllogisms with contingent or false premisses. The alternative conception of necessity is then introduced by him in order to make good this deficiency. The distinction between the necessity of being and the necessity of saying was revived by the Oxford logician E. W. B. Joseph, and taken over by Frank Ramsey in his seminal Truth and Probability, but has not received attention from recent interpreters of Aristotle's logic. This paper, however, argues that, in spite of its intrinsic interest, the distinction bore no significant fruit in Aristotle's logical doctrine. (shrink)

Humanity entered the twenty-first century with revolutionary achievements in biomedical research. At the same time multiple “dual-use” results have been published. The battle against infectious diseases is meeting new challenges, with newly emerging and re-emerging infections. Both natural disaster epidemics, such as SARS, avian influenza, haemorrhagic fevers, XDR and MDR tuberculosis and many others, and the possibility of intentional mis-use, such as letters containing anthrax spores in USA, 2001, have raised awareness of the real threats. Many great men, including Goethe, (...) Spinoza, J.B. Shaw, Fr. Engels, J.F. Kennedy and others, have recognized that liberty is also a responsibility. That is why the liberty to decide now represents an acknowledged necessity: biomedical research should be supported, conducted and published with appropriate measures to prevent potential “dual use”. Biomedical scientists should work according to the ethical principles of their Code of Conduct, an analogue of Hippocrates Oath of doctors; and they should inform government, society and their juniors about the problem. National science consulting boards of experts should be created to prepare guidelines and control the problem at state level. An international board should develop minimum standards to be applicable by each country. Bio-preparedness is considered another key-measure. (shrink)

What makes the rule of law so special that it is to conscientiously punish the â oebadâ doers and reward the â oegoodâ onesâ "such that, where there is the rule of law, peace and order are to be expected, so that â oethe rule of law is better than the rule of any individualâ? Take the case of international law, as an illustration. While different international courts have been busy going after the killers of innocent victims in Rwanda and (...) Liberia, they have turned a blind eye to the major powers which have killedâ "on a much larger and more brutal scale, by comparisonâ "innocent civilians in Iraq and Afghanistan, just to cite two current examples. Contrary to the conventional wisdom conveniently held by many in human history, the rule of law has its other side which has not yet been systematically understood, such that the rule of law is neither possible nor desirable to the extent that the defenders of legal institutions in human history would like us to believe. Lest any misunderstanding hastily occur, this is not to imply that the rule of law is absolutely useless, or that the literature in jurisprudence (and other related fields like political philosophy, ethics, law and economics, and the sociology of law) should be dismissed because of its scholarly irrelevance. Of course, neither of these two extreme views is reasonable either. Instead, this book provides an alternative (better) way to understand the nature of law, in relation to its necessity and contingency in the context of justiceâ "while learning from different approaches in the literature but without favoring any one of them (nor integrating them, since they are not necessarily compatible with each other). In the process, this book offers a new theory to transcend the existing approaches in the literature in a new directionâ "in that, in the end, there is no justice without injustice and that it will be transcended too. This seminal project, if successful, will fundamentally change the way that we think about the nature of law, from the combined perspectives of the mind, nature, society, and culture, with enormous implications for the human future and what I originally called its â oepost-humanâ fate.

The modern belief that mindless forces can be ultimate efficient causes of natural events is a conceptual impossibility. The logically ultimate cause of any change, the something that is ultimately making it occur in the present moment, is either a mind or not. More specifically, the cause either chooses to act or it does not. By choice here, I mean an act of free will in the libertarian sense. Where there is choosing in this sense there must be a mind. (...) And when we say that an agent acts thus freely, we mean that it acts without being causally determined to act by anything beyond itself. However, this is conceptually indistinguishable from the idea of an ultimate efficient cause. To say that an agent is the ultimate cause in a causal chain is, by definition, to say that it acts without being caused to act by anything beyond itself. It is the head of the causal chain. It is, therefore, a matter of conceptual necessity that ultimate causes be minds, a fact that we have been blind to since the Scientific Revolution on the bad analogy of machines. Thus, every force ultimately governing the universe must be a mind corresponding either to the polytheist’s or the monotheist’s generic definition of divinity, and monotheism’s eternal mind will always be the most complete and justifiable explanation for the existence of the universe as a whole, even for the existence of the gods themselves.

Proponents of the necessity of material origins hold roughly that an entity’s originating matter could not have been radically different from its actual originating matter. Sungil Han defends the considerably stronger position that an entity’s originating matter could not have been at all different from its actual originating matter. I raise some worries for Han’s key premise as it pertains to biological origins, and discuss certain methodological limitations of Han’s project as it pertains to the origins of artifacts.

Empiricist theories of knowledge are attractive for they offer the prospect of a unitary theory of knowledge based on relatively well understood physiological and cognitive processes. Mathematical knowledge, however, has been a traditional stumbling block for such theories. There are three primary features of mathematical knowledge which have led epistemologists to the conclusion that it cannot be accommodated within an empiricist framework: 1) mathematical propositions appear to be immune from empirical disconfirmation; 2) mathematical propositions appear to be known with certainty; (...) and 3) mathematical propositions are necessary. Epistemologists who believe that some nonmathematical propositions, such as logical or ethical propositions, cannot be known a posteriori also typically appeal to the three factors cited above in defending their position. The primary purpose of this paper is to examine whether any of these alleged features of mathematical propositions establishes that knowledge of such propositions cannot be a posteriori. (shrink)

Genetic intervention is on the near horizon for the treatment of substance abu se. Genetic intervention involves a reprogramming of a person’s own genetic instructions so that that person will no longer have the physical craving for the drug of choice. Unlike pharmacologic intervention, genetic intervention will change the genetic identity of the person, albeit slightly. The legal issue is whether one has a fundamental right to this medical procedure. A fundamental right is one that the government cannot deny without (...) a compelling interest. The case law indicates that the right o f medical necessity applies when the person’s affliction is serious, there are no reasonable or effective alternatives, the person did not intentionally cause the condition, and the treatment is effective for the long term. Unlike the medical marijuana ph enomenon, genetic intervention is per se anti - drug, unrelated to illegal, recreational drug use, and on its face has a medical use. Legal doctrines to date though not directly on point are conceptually compatible with the existence of a fundamental right of medical necessity for genetic intervention. (shrink)

It is standard to think that in Spinoza’s system, all things are necessary and in no sense contingent. However, in his classic book, Spinoza’s Metaphysics, published in 1969, Edwin Curley argues based on the proposition 28 of the first part of the Ethics that Spinoza endorses necessitarianism of only a modest kind, according to which when it comes to finite modes, there is a sense in which they are contingent. In this paper, I revisit Curley’s argument. Commentators have responded to (...) Curley’s argument, showing that Spinoza’s remarks on infinite modes entail that finite modes can in no sense be contingent. But this alone falls short of dispelling Curley’s misgivings about the standard interpretation, for it remains unexplained why Curley is wrong in thinking that the proposition 28 supports his moderate necessitarian interpretation. In defense of the standard interpretation, I bolster the usual response to Curley in greater detail than has been done in the literature and explain why, pace Curley, the proposition 28 plays no evidential role in support of Curley’s interpretation.

Dystopias matter because they make us think.

It's crucial to keep imagining that things could get better, and furthermore to imagine how they might get better. … So (...) by force of will or the sheer default of emergency we make ourselves have utopian thoughts and ideas. This is the necessary next step following the dystopian moment, without which dystopia is stuck at a level of political quietism... (shrink)

John Locke is often understood as the inaugurator of the modern discussion of personal human identity—a discussion that inevitably falls back on his own theory with its critical reliance on memory. David Hume and Sigmund Freud would later make arguments for what constituted personal identity, both relying, like Locke, on memory, but parting from Locke's company in respect the role that memory played. The purpose of this paper will be to sketch the groundwork for Locke's own theory of personal identity (...) and consider some common objections tied to his special reliance on memory. Then, we will investigate the extent to which Hume and Freud refined their respective concepts of self-identity in ways that escape some of the most intractable objections to Locke's theory in its dependence on memory. Finally, we will consider which theorist's conception of self-identity best accords with our notion of the cyber-self, or psychological subjectivity in the context of cyberspace. For Locke, the nature of self-identity is that it is continuous across time, and to remain uninterrupted it must be beholden to a psychological process, rather than a material or immaterial substance.

The relation between free will and necessity is one of the most important issues regarding the problem of “free will”. This is because of the rule which indicates that “being not necessary, an event would not be came off”. There has been an ongoing debate among theologians, philosophers and Jurists on whether this rule includes free actions. Sadrain Philosophers believe that this rule is inclusive of human free actions, while followers of the Na’eeni school endorse the opposite. In this (...) article, after reviewing the views of philosophers and jurists on the stages of a free action, I shall explore the question whether human actions, stages of which are understood deterministic, could be regarded as free, and so, whether Na’eenian criticisms against philosophers are justified. Besides, I shall put forth some innovative ideas of Allameh Ja’fari concerning the issue, whose view, while revises some philosophers’, is not compatible with that of Na’eeni. (shrink)

Abstract: In this article, two philosophical positions that structure distinct approaches in the history of metaphysics and epistemology are briefly characterized and contrasted. While one view, “naturalism,” rejects an a priori commitment to necessity, the other view, “transcendentalism,” insists on that commitment. It is shown that at the level of the fundamentals of thought, judgment, and reason, the dispute dissolves, and the naturalists' employment of “necessity for all practical purposes” is at best only nominally distinct from the transcendentalists' (...) use of the same concept.

Stephen Mumford and Rani Lill Anjum have argued that a theory of free will that appeals to a powers-based ontology is incompatible with causal determinism. This is a surprising conclusion since much recent work on the intersection of the metaphysics of powers and free will has consisted of attempts to defend compatibilism by appealing to a powers-based ontology. In response I show that their argument turns on an equivocation of ‘all events are necessitated’.

What is the source of the hardness of the logical must? What does the necessity of mathematical and logical inference consist in? If I am plotting the curve y = x2 and assume that x = 2 I must conclude that y = 4; no other consequence can be drawn. What is the nature of this ‘must'?Understanding Wittgenstein's answer to this question is essential to understanding his later philosophy. The question of the nature of logical or mathematical necessity (...) is as fundamental for the Investigations as it obviously was for the Tractatus. Barry Stroud's article “Wittgenstein and Logical Necessity” certainly is still one of the most illuminating and important of the papers dealing with this question. (shrink)

Philosophers traditionally interpret Kant as a retributivist, but modern interpreters, with reference to Kant’s theory of justice and problematic passages, instead propose penal theories that mix retributive and deterrent features. Although these mixed penal theories are substantively compelling and capture the Kantian spirit, their dual aspects lead to a justificatory conflict that generates an apparent dilemma. To resolve this dilemma and clear the ground for these mixed theories, I will outline and reinterpret Kant’s penal theory by situating it in his (...) broader moral and political philosophy. This move grounds the followability requirement, which is necessary to resolve the dilemma. (shrink)

Analytic philosophers are often said to be indifferent or even hostile to the history of philosophy – that is, not to the idea of history of philosophy as such, but regarded as a species of the genus philosophy rather than the genus history. Here it is argued that such an attitude is actually inconsistent with approaches within the philosophies of mind that are typical within analytic philosophy. It is suggested that the common “argument rather than pedigree” claim – that is, (...) that claim that philosophical ideas should be evaluated only in the context of the reasons for or against them, and not in terms of historical conditions that brought them about – presupposes an early modern “egological” conception of the mind as normatively autonomous, and that such a view is in contradiction with the deeply held naturalistic predispositions of most contemporary philosophers of mind. Using the example of Wilfrid Sellars, who attempted to combine “naturalist” and “normative” considerations in his philosophy of mind, it is argued that only by treating the mind as having an artifactual dimension can these opposing considerations be accommodated. And, if the mind is at least partly understood as artifactual, then, to that extent, like all artifacts, it is to be understood via a narrative about the particular human activities in which those artifacts are produced and in which they function.

During 2017, churches with their roots in the 16th-century Reformation, will be celebrating the legacy of the Reformation. It affords theologians and churches the opportunity to reflect on the principles of the Reformation and its relevance at the start of the 21st century. This contribution reflects on the question of the necessity of church reformation, based on three texts from different periods in the history of the church. Firstly and primarily, Calvin's 'De necessitate reformandae ecclesiae' of 1543 sheds light (...) on the issues the 16th century reformers were faced with and why they believed the church needed reformation. Calvin had a very clear view on the necessity of church reformation, but that it should also come to some conclusion once the liturgy and doctrine are in order. The question of church reformation is then further discussed in the light of two other texts, one from Jodocus van Lodenstein and Karl Barth. All agree on the necessity of church reformation, but differ in terms of theological and practical implications. The contribution concludes with a few remarks on the modern maxim 'ecclesia semper reformanda'. (shrink)

J. Ladyman, Ladyman and Ross refine J. Worral's structural realism, by developing an ontic structural realism which they argue is a consistently naturalistic means of characterizing the ontology of fundamental physics. I argue that elements of analytic metaphysics strengthen and refine their project of characterizing fundamental physics via OSR and by extension, their presentation of information-theoretic structural realism. I refine this point by situating M. Lange’s discussion of nomological modality qua natural necessity within Ladyman and Ross’s discussion of ITSR. (...) The logical hierarchy evinced in Lange’s ‘nomic stability’ further extends and refines Ladyman and Ross’s claims through the addition of nuanced modal distinctions in a systematic framework. (shrink)
