The causal argument for physicalism is anayzed and it's key premise--the causal closure of physics--is found wanting. Therefore, a hidden premise must be added to the argument to gain its conclusion, but the hidden premise is indistinguishable from the conclusion of the causal argument. Therefore, it begs the question on physicalism.

Apparently, relationships between God (if He exists) and His creatures would be very valuable. Appreciating this value raises the question of whether it can motivate a certain premise in John Schellenberg’s argument from divine hiddenness, a premise which claims, roughly, that if some capable, non-resistant subject fails to believe in God, then God does not exist. In this paper, I argue that the value of divine–creature relationships can justify this premise only if we have reason to believe (...) that the counterfactuals of freedom work out in certain ways. Unfortunately, we can’t acquire such a reason, at least not without relying on other successful arguments (if there are any) for the relevant premise of Schellenberg’s hiddenness argument. (shrink)

The paper refers to the argument from hiddenness as presented in John Schellenberg’s book The Hiddenness Argument and the philosophical views expressed there, making this argument understandable. It is argued that conditionals (1) and (2) are not adequately grounded. Schellenberg has not shown that we have the knowledge necessary to accept the premises as true. His justifications referring to relations between people raise doubts. The paper includes an argument that Schellenberg should substantiate its key claim that God has the resources (...) to accommodate the possible consequences of openness to a relationship with finite persons, making them compatible with the flourishing of all concerned and of any relationship that may come to exist between them. At the end of the text, I propose to treat the argument as a rejection of an anthropomorphic God. (shrink)

J.L. Schellenberg argues that divine hiddenness provides an argument for the conclusion that God does not exist, for if God existed he would not allow non-resistant non-belief to occur, but non-resistant non-belief does occur, so God does not exist. In this paper, I argue that the stakes involved in theistic considerations put pressure on Schellenberg’s premise that non-resistant non-belief occurs. First, I specify conditions for someone’s being a resistant non-believer. Then, I argue that many people fulfill these conditions because, (...) given some plausible assumptions, there is a very good pragmatic reason to be a theist rather than an atheist. I assume it is more likely that theists go to heaven than atheists, and I argue there is a non-zero probability that one can receive infinite utility and a method of comparing outcomes with infinite utilities in which the probability of each outcome affects the final expected values. Then, I show how this argument entails there is no good reason to think that there are very many non-resistant non-believers. (shrink)

The paper considers premises of the hiddenness argument with an emphasis on its usage of the concept of a personal God. The paper’s assumption is that a recent literature on second-person experiences could be useful for theists in their efforts to defend their position against Schellenberg’s argument. Stump’s analyses of a second-person knowledge indicate that what is required in order to establish an interpersonal relationship is a personal presence of the persons in question, and therefore they falsify the thesis that (...) a minimalist requirement for a relationship between a man and God has to be belief in his existence. Recent works by developmental psychologists not only verify a hypothesis that a second-person knowledge is not reducible to knowledge-that, but also suggest that one needs a shared form of life in order to establish an interpersonal relationship. These two insights allow the author to formulate his own response to the hiddenness argument: only when God’s presence is non-explicit—for example, when God is hidden in a human nature—can a finite person enter into a personal relationship with him. It is the fulfilment of the requirement of being personally present that is the justifying reason for God to permit non-resistant non-belief. (shrink)

John Schellenberg has advanced the hiddenness argument against God’s existence, based on the idea that an all-loving God would seek personal relationships. This paper develops a reply to Schellenberg’s argument by examining the notion of moral impurity, as understood by Paul the Apostle. Paul conceptualized moral impurity as a causal state that transfers from person to person, like a contagious disease. He also believed that moral impurity precludes divine-human relationship. The goal of this paper is to develop these ideas into (...) a problem for one Schellenberg’s key premises. (shrink)

Recently it was shown that certain fluid-mechanical ‘pilot-wave’ systems can strikingly mimic a range of quantum properties, including single particle diffraction and interference, quantization of angular momentum etc. How far does this analogy go? The ultimate test of quantumness of such systems is a Bell-test. Here the premises of the Bell inequality are re-investigated for particles accompanied by a pilot-wave, or more generally by a resonant ‘background’ field. We find that two of these premises, namely outcome independence and measurement independence, (...) may not be generally valid when such a background is present. Under this assumption the Bell inequality is possibly violated. A class of hydrodynamic Bell experiments is proposed that could test this claim. Such a Bell test on fluid systems could provide a wealth of new insights on the different loopholes for Bell’s theorem. Finally, it is shown that certain properties of background-based theories can be illustrated in Ising spin-lattices. (shrink)

A: Things that are equal to the same are equal to each other. B: The two sides of this triangle are things that are equal to the same. Z: So, the two sides of this triangle are equal to each other. Achilles fails because he encounters an infinite progression of hidden premises of the form “If all the premises of the argument are true, the conclusion is true”. In [a1], the hidden premise is H1 “If A and (...) B then Z” – surely, if one did not believe that H1 is true, one would have a reason not to accept the conclusion Z. So, the argument [a2] must lead to conclusion Z from A, B and H1. But, one will have to supplement [a2] with H2: “If A and B and H1 then Z” since if one did not believe H2 one would have a reason not to draw conclusion Z. And so on ad infinitum. The puzzle can be seen as arising through the application of an apparently innocent principle of discerning missing premises (§2). If looked at in this light, the standard response given to the paradox does not so much resolve the puzzle as legislates against it being raised with respect to principles of inference (§3). I argue that a fundamental ambiguity infests the test for what is a missing premise (§4). Moreover, it explains why the puzzle appears to, though it does not (§5), arise. I end with some comments on the usefulness of the test (§6). (shrink)

The article discusses a response to Schellenberg’s atheistic ‘hiddenness argument’ that neither objects to its premises nor formulates a new inductive argument in favour of the existence of God. According to the proposed response, it is sufficient for the task of defending theism to reverse Schellenberg’s reasoning and present a theistic meta-argument that takes as its assumption the fact that there are resistant believers in the world. The paper defends the claim that both arguments have similar persuasive power. However, because (...) of their contradictory conclusions both cannot be sound. It is argued that the way to decide the dilemma is to compare the demographics of theism and atheism and to compare accommodation strategies of both arguments. The first comparison favours theism, but it does not exclude the possibility that quantitative proportions between theists and atheists can change in the future. The second comparison refers to accommodation strategies of proponents of A-argument who have to give an account of how it is possible that in an atheistic world there exist resistant believers and of proponents of T-argument who have to give an account of how it is possible that in the world governed by an all-powerful and all-loving God there exist nonresistant nonbelievers. The conclusion of the considerations is the claim that the theistic accommodation strategy compares favourably to the atheistic one. (shrink)

Arguments from divine hiddenness attempt to show that God, as understood by traditional Christianity, does not exist.Eleonore Stump has argued that, contrary to a key premise in such arguments, it is possible for God to have a personal relationship with human beings who do not believe that he exists. I describe Stump’s account of the will and describe its connection to her explanation of divine hiddenness. Specifically, I show that her account of the knowledge of persons cannot solve the (...) problem of divine hiddenness. I also argue that Stump’s account of the will commits her to the claim that lacking belief in God’s existence entails resistance to God’s grace. (shrink)

J. L. Schellenberg's argument from hiddenness against the existence of God is simple. The primary argument is as follows.The Main Argument from Hiddenness If God exists, then no one would be epistemically rational for not believing in God. Some people are epistemically rational for not believing in God. Therefore, God does not exist.However, much of the issue concerning this argument surrounds the support for premise. As many have noted, Schellenberg's first premise does not demand an undeniable, incontrovertible proof (...) for God's existence. He merely claims that God would provide evidence sufficient for rational belief, and presumably this would entail that the only people who do not believe are culpable for their nonbelief. Their nonbelief would be their own fault. (shrink)

Some philosophers have argued that the paucity of evidence for theism — along with basic assumptions about God's nature — is ipso facto evidence for atheism. The resulting argument has come to be known as the argument from divine hiddenness. Theists have challenged both the major and minor premises of the argument by offering defences. However, all of the major, contemporary defences are failures. What unites these failures is instructive: each is implausible given other commitments shared by everyone in the (...) debate or by theists in particular. Only challenges which are plausible given both common sense and other theistic commitments will undermine the argument from divine hiddenness. Given that such defences universally fail, the best hope for a successful challenge to the argument comes from more general sceptical responses. This sort of response is briefly sketched and defended against four independent objections. (shrink)

This paper criticizes one of the premises of Schellenberg’s atheistic argument from divine hiddenness. This premise, which can be considered as the foundation of his proposed argument, is based on a specific interpretation of divine love as eros. In this paper I first categorize several concepts of divine love under two main categories, eros and agape; I then answer some main objections to the ascription of eros to God; and in the last part I show that neither on a (...) reading of divine love as agape nor as eros can Schellenberg’s argument be construed as sound. My aim is to show that even if -- contra Nygren for example -- we accept that divine love can be interpreted as eros, Schellenberg’s argument still doesn’t work. (shrink)

Merleau-Ponty and a Phenomenology of PTSD begins from the premise that trauma can be better treated if it is better understood.

In regards to the problem of evil, van Inwagen thinks there are two arguments from evil which require different defenses. These are the global argument from evil—that there exists evil in general, and the local argument from evil—that there exists some particular atrocious evil X. However, van Inwagen fails to consider whether the problem of God’s hiddenness also has a “local” version: whether there is in fact a “local” argument from God’s hiddenness which would be undefeated by his general defense (...) of God’s hiddenness. This paper will argue that van Inwagen’s present account contains no implicit response to the “local” argument from God’s hiddenness, and, worse, the “local” argument brings to the fore crucial inconsistencies in van Inwagen’s account. These inconsistencies concern van Inwagen’s criterion for philosophical success—his methodological use of an “ideal audience” in an ideal debate—and a crucial premise in his argument: namely, that people who do not believe in God are culpably deceiving themselves regarding the manifest presence of God. These considerations will be a platform for my arguing that the failures of van Inwagen’s account amount to his ignoring the extra-rational, concrete aspect of grasping “spiritual propositions”—propositions which, in order to be affirmed, require the full self-understanding which precipitates out of the mind, body, and will of a particular existing individual.

This paper discusses the fundamental sense in which the components of an argument should be relevant to the intended audience. In particular, the evidence advanced should be relevant to the facts and assumptions that are manifest in the cognitive environment of the audience. A version of Sperber and Wilson's concept of the cognitive environment is applied to argumentative concerns, and from this certain features of audience-relevance are explored: that the relevance of a premise can vary with the audience; that (...) irrelevant premises can be made relevant; that evidence can be relevant by degrees; and that this notion of relevance will assist the argumentation analyst in the identification and assessment of hidden premises.

My hypothesis is that the attempts to justify the thesis that the substance has exactly one principal attribute have not yet succeeded because they underestimated the contribution brought about by the transformation of the notion of nature entailed by the introduction of the concept of principal attribute. Understanding the Cartesian proof of substantial dualism, and more particularly the "attribute premise", would involve, I suggest, the thesis according to which the concept of principal attribute, insofar as it expresses the essence of the substance, is not, and cannot be, according to Descartes, an abstract universal, but rather one of a particular nature.

The goal of this article is to address the problem of inconsistent models and the challenge it poses for perspectivism. I analyze the argument, draw attention to some hidden premises behind it, and deflate them. Then I introduce the notion of perspectival models as a distinctive class of modeling practices whose primary function is exploratory. I illustrate perspectival modeling with two examples taken from contemporary high-energy physics at the Large Hadron Collider at the European Organization for Nuclear Research, which (...) are designed to show how a plurality of seemingly incompatible models is methodologically crucial to advance the realist quest in cutting-edge areas of scientific inquiry.

In attempting to derive irreversible macroscopic thermodynamics from reversible microscopic dynamics, Boltzmann inadvertently smuggled in a premise that assumed the very irreversibility he was trying to prove: ‘molecular chaos.’ The program of ‘Einselection’ within Everettian approaches faces a similar ‘Loschmidt’s Paradox’: the universe, according to the Everettian picture, is a closed system obeying only unitary dynamics, and it therefore contains no distinguishable environmental subsystems with the necessary ‘phase randomness’ to effect einselection of a pointer observable. The theoretically unjustified assumption (...) of distinguishable environmental subsystems is the hidden premise that makes the derivation of einselection circular. In effect, it presupposes the ‘emergent’ structures from the beginning. Thus the problem of basis ambiguity remains unsolved in Everettian interpretations. (shrink)

Semen Frank (1877–1950) was one of the first and most ardent advocates of the ontological argument in the twentieth century. He proposed an original interpretation of the ontological argument based on its analogy to Descartes’ Cogito. Frank believed that it is possible to develop Cogito ergo sum into Cogito ergo est ens absolutum. In this paper, I analyze his version of the ontological argument. First, I propose a simple reconstruction of his reasoning, paying attention to its hidden premise. (...) Second, departing from the classical logical interpretations of Descartes’ argument, I show that for Frank the claim that God exists had the same logical properties as Cogito. As a result, it seems that his argument was formally correct, though based on a premise which could hardly be convincing for a non-believer. This should not be surprising, however, since Frank, as most Russian religious philosophers, was not interested in the project of philosophical theology. His main concern was rather the development of philosophy based on religious premises, which might be called “theological philosophy”. (shrink)

In his article entitled 'Divine hiddenness and the demographics of theism' ("Religious Studies", 42 (2006), 177–191), Stephen Maitzen draws our attention to an important feature that is often overlooked in discussion about the argument from divine hiddenness (ADH). His claim is that an uneven distribution of theistic belief (and not just the mere existence of non-belief) provides an atheological challenge that cannot likely be overcome. After describing what I take to be the most pressing feature of the problem, I argue (...) that a hidden premise causes Maitzen to overlook a Molinist solution. The upshot is a softening of the atheological import of the demographic data. (shrink)

Recently, the possibility of misrepresentation has resurfaced in the debate between higher-order thought theorists and their opponents. One new element in the debate has been the rare cases of Charles Bonnet syndrome , proposed as empirical evidence for misrepresentation as posited by the higher-order theories. In this article I will spell out the argument supposedly underlying the claim that the RCB cases are genuine empirical evidence of misrepresentation. I will then proceed to show that this argument relies on a (...) class='Hi'>hidden premise. With this premise exposed the argument cannot support the notion of misrepresentation posited by higher-order theories. (shrink)

Recent policy debates are commonly framed as questions of “sci-ence” versus “ideology”. This is seen in polemics around issues that can be informed by bio–medical or geo–physical sciences: the coronavirus pandemic and climate change. The paper explores the basis for claims of difference between science and ideology: truth versus delusion; representations of reality and the means for interpreting it; and their relation to conflicting interests. Each of these three characteristics of ideology is explored by relating them to the methods of (...) the sciences. Three questions are derived from that analysis: Does science hide premises or assumptions; or, conversely, does it proceed by unmasking hidden premises in rival scientific positions? Are the facts of science immediately interpretable, or are they embedded in a web of methodological and metaphorical operations? Are the operations of science insulated from human interests, conflicts, and ethical considerations for how one should live? These are then approached through a compressed case study of three phases of medical science: neo– Platonic herbal studies deriving from Paracelsus; the Enlightenment development of clinical medicine; and the development of immunology from the nineteenth to the twenty–first century. The concluding section draws on the case studies to answer the three questions. Each of the key elements of ideology is shown to also be involved in scientific reasoning. The development of medical science demonstrates that semiotic operations characteristic of ideology are also found in good scientific practice. In conclusion, it is proposed that science is better off for having learned from ideology. Critique is an epistemic virtue; images and metaphors enrich scientific thinking; and science will better serve humanity as its connections to the interests of all species, and to the Earth itself, are exposed.

Misinformation can have significant societal consequences. For example, misinformation about climate change has confused the public and stalled support for mitigation policies. When people lack the expertise and skill to evaluate the science behind a claim, they typically rely on heuristics such as substituting judgment about something complex (i.e. climate science) with judgment about something simple (i.e. the character of people who speak about climate science) and are therefore vulnerable to misleading information. Inoculation theory offers one approach to effectively neutralize (...) the influence of misinformation. Typically, inoculations convey resistance by providing people with information that counters misinformation. In contrast, we propose inoculating against misinformation by explaining the fallacious reasoning within misleading denialist claims. We offer a strategy based on critical thinking methods to analyse and detect poor reasoning within denialist claims. This strategy includes detailing argument structure, determining the truth of the premises, and checking for validity, hidden premises, or ambiguous language. Focusing on argument structure also facilitates the identification of reasoning fallacies by locating them in the reasoning process. Because this reason-based form of inoculation is based on general critical thinking methods, it offers the distinct advantage of being accessible to those who lack expertise in climate science. We applied this approach to 42 common denialist claims and find that they all demonstrate fallacious reasoning and fail to refute the scientific consensus regarding anthropogenic global warming. This comprehensive deconstruction and refutation of the most common denialist claims about climate change is designed to act as a resource for communicators and educators who teach climate science and/or critical thinking.

According to an optimistic view, affective empathy is a route to knowledge of what it is like to be in the target person’s state (“phenomenal knowledge”). Roughly, the idea is that the empathizer gains this knowledge by means of empathically experiencing the target’s emotional state. The literature on affective empathy, however, often draws a simplified picture according to which the target feels only a single emotion at a time. Co-occurring emotions (“concurrent emotions”) are rarely considered. This is problematic, because concurring (...) emotions seem to support a sceptical view according to which we cannot gain phenomenal knowledge of the target person’s state by means of affective empathy. The sceptic concludes that attaining the epistemic goal of affective empathy is difficult, in practice often impossible. I accept the sceptic’s premises, but reject the conclusion, because of the argument’s unjustified, hidden premise: that the epistemic goal of affective empathy is phenomenal knowledge. I argue that the epistemic goal of affective empathy is phenomenal understanding, not knowledge. Attention to the under-explored phenomenon of concurring emotions clarifies why this is important. I argue that this is the decisive epistemic progress in everyday cases of phenomenal understanding of another person. (shrink)

Historians and philosophers of science have, in recent decades, offered evidence in support of several influential models of conceptual change in science. These models have often drawn on and in turn driven research on conceptual change in childhood and in science education. This nexus of reciprocal influences is held together by several largely unexamined analogies and by several assumptions concerning analogy itself. In this chapter, we aim to shed some light on these hidden premises and subject them to critical (...) scrutiny. Our critical survey suggests the following hypothesis: conceptual change in both childhood and science is driven by the epistemic subject’s quest for coherence. (shrink)

After all, philosophers of applied ethics do the same as all other philosophers: they analyze concepts, use certain strategies to test or justify beliefs, and explicate hidden premises in (...) arguments.

The article outlines the prospects of using J. Hintikka’s interrogative epistemology for modelling cognitive operations carried out by a cognizing agent to create a machine capable of full cognition. It was established that modeling is divided into two objectives: modeling the cognitive operations and modeling the strategic reasoning. Interrogative epistemology presents a solution to the first objective. It relies on a game-theoretic formal apparatus that allows one to correctly describe all types of possible moves within the framework of a particular (...) cognitive game. The second objective cannot be accomplished in a general epistemological theory framework since strategic considerations about the organization of research and even the concept of knowledge inevitably depend on the broader context of an agent’s practical activity. Therefore, interrogative epistemology does not claim a universal and complete description of the process of cognition, focusing on other tasks: primarily on identifying hidden premises that cognitive agents use in their reasoning. For the same reason, interrogative epistemology deems the possibility of the existence of a cognizing machine as formally unsubstantiated and questionable. However, arguments are given in favor of the fact that interrogative epistemology serves as an acceptable conceptual framework for clarifying the nature of the difficulties that arise with attempts to accomplish the second objective and improving the quality of philosophical discourse in the field of artificial intelligence research. The author substantiates this position by arguing that the ability to cognize presupposes the ability to perform all the essential functions that are usually called mental. (shrink)

In this paper, we present an abductive argument for the existence of God from the experience of awe at natural beauty. If God’s creative work is a viable explanation for why we experience awe at natural beauty, and there is no satisfactory naturalistic explanation for the origins of such experiences, then we have defeasible evidence that God exists. To evaluate the argument's tenability, we assess the merits of the two main naturalistic frameworks that can be marshaled to answer the question (...) of why human beings experience awe at natural beauty, Wilson's biophilia hypothesis, and Keltner and Haidt's prototype approach to awe. We show shortcomings of both accounts in explaining the relevant experiences and argue that the reliance of these accounts on an adaptationist reading of our aesthetic appreciation of nature entails a commitment to questionable hidden premises: that affordances themselves can figure in the subject's perceptual experience, and that experiences of awe have adaptive value. We maintain that the argument's “empirical” premise is tenable and conclude with directions for future research regarding the argument's “theological” premise. (shrink)

Prompted by questions raised in the public arena concerning the validity of arguments for the existence of God based on “design” in the universe, I exploretraditional teleological argument for the existence of God.

To justify the premises of Aquinas’s argument, (...) I begin by presenting an argument to justify the existence of “final causes,” with a focus on answering questions about the biological implications of these causes for evolutionary theory.

Cogency is the central normative concept of informal logic. But it is a loose evaluative concept and I argue that a generic notion covering all of the qualities of a well-reasoned argument is the most plausible conception. It is best captured by the standard RSA criterion: in a good argument acceptable (A) and relevant (R) premises provide sufficient (S) grounds for the conclusion. Logical qualities in a broad sense are affected by the epistemic qualities of the premises and “consequence” in (...) a broad sense exhibits an interplay of form and content. There are four proposals for the premise—conclusion relation: (i) no strictly logical connection (“non-logical” consequence); (ii) one type of connection only (deductivism); (iii) a few types of connection (deduction, induction, perhaps conduction and analogical reasoning); (iv) many types of connection (argumentation schemes). Deductivism is a serious option but in its strong version, as the discussion about petitio shows, it fails to establish that arguments which are not cogent are thereby invalid. And weak deductivism, very attractive from the pedagogical point of view, has some deficiencies (implausible hidden premises; preservation of truth, not probability). I argue that the idea of a counterexample, when we regard certain components of the argument as fixed and others as variable, is the best approach to the analysis of the illative core of every-day arguments (the approach of David Hitchcock on material consequence).

Rights are not redundant elements of a plausible utilitarian theory and the right to life is an inseparable companion of the rights to nourishment and to medical care.

The hidden premise of Singer’s rebuttal of involuntary euthanasia is a (...) theory of rights as vetoes against imposed benefits. Without openly subscribing to such a theory there is no answer to ‘logical slippery slope’ arguments and no protection against dangerous ‘quality of life’ considerations as a basis of decisions over life and death.

The Meno has traditionally been viewed as "one of Plato's earliest and most noteworthy forays into epistemology." In this dialogue, and in the course of a discussion between Socrates and his young interlocutor, Meno, about the nature of virtue and whether it can be taught, “Meno raises an epistemological question unprecedented in the Socratic dialogues.” This question - or rather, dilemma - has come to be known in the philosophical literature as Meno’s Paradox of Inquiry, due its apparently containing an (...) easy-to-detect equivocation of the word ‘know’. Immediately after the paradox, and in an apparent response to it, Socrates recounts a myth: a story told by priests and priestesses about the pre-natal existence and immortality of the soul. From this this myth, Socrates concocts the infamous theory of recollection – a theory according to which the soul has acquired knowledge of everything before it was born, while in a disincarnate state. According to the traditional reading of Meno’s paradox, this theory constitutes Plato’s response to it. The traditional reading has come under fire in recent years by advocates of the epistemological reading, who argue that the theory of recollection is not Plato’s intended response to the paradox. Instead, they suggest, Plato’s distinction between true belief and knowledge – which appears towards the end of the dialogue – is sufficient for solving the paradox; and as such, it ought to be read as Plato’s response to it. In this thesis, I argue against ERM’s claim that a mere epistemological distinction is all it takes to solve the paradox. To do so, I explore the metaphysics of change in Plato’s ontology. From this, I appeal to our everyday notion of ‘memory’ in order to show that Meno’s paradox, in fact, contains a hidden-premise, which when laid bare, reveals two distinct challenges contained within the argument: a superficial one, and a deeper one. I argue that although it appears at first blush as though the former could easily be dismissed as an equivocation, to which the epistemological distinction between belief and knowledge could provide an answer, the latter cannot. This is because the deeper challenge threatens the very preconditions of knowledge itself – that is to say, it renders cognition impossible – and, as such, it cancels out any effort to provide an epistemological response to the superficial challenge. Hence, unless the deeper-level challenge is satisfactorily disarmed, both challenges remain unanswered. I argue that although the major motivation for the theory of recollection in the Meno is indeed to provide an answer to scepticism about knowledge, nevertheless, it ought to be understood, first, as a theory of cognition – i.e. as a theory about the preconditions and atomic building blocks of knowledge – and not a theory of knowledge per se. This answer comes in the form of a radical theory of the mind and cognition – one that stands in stark opposition to our common-sense views about the mind: a view from which, Plato believed, the paradox arises. Drawing on recent debates between Nativists and Empiricists in the Cognitive Sciences, I argue that it was a great achievement of Plato’s to grasp that our common-sense view about the mind, and its concomitant process of learning, language acquisition and knowledge acquisition, might in fact be at the very root of scepticism about our ability to engage in meaningful philosophical practice, and our ability to acquire objective knowledge – especially, objective moral knowledge. The Meno’s paradox, then – so I contend - is not a puzzle whose solution rests upon merely pointing to an epistemological distinction between true belief and knowledge, as advocates of ERM have suggested. Rather, it is a puzzle about cognition. More precisely, it is a puzzle that targets the rudimentary cognitive stages of initial cognition and truth-recognition - one whose solution entails offering an account of the mind that would make these elementary cognitive processes possible. Accordingly, Plato’s theory of recollection in the Meno ought to be read as an attempt to map the structure of the mind, and as such, to provide an account of cognition. In doing so, he intended to put forward a view about the preconditions of knowledge – the sort of preconditions without which language acquisition and knowledge acquisition would simply not be possible. With this theory, Plato has the beginnings of an argument against the kind of relativism and scepticism prevalent at his time. As such, a correct interpretation of the so-called paradox of inquiry should approach it as a puzzle about mind and cognition – and not solely as an epistemological one, as it has previously been treated.

Prompted by questions raised in the public arena concerning the validity of arguments for the existence of God based on “design” in the universe, I explore a traditional teleological argument for the existence of God. Using the arguments offered by Thomas Aquinas as fairly representative of this classical line of argumentation going back to Aristotle, I attempt to uncover the hidden premises and construct arguments for the existence of God which are deductive in nature. To justify the premises of (...) Aquinas’s argument, I begin by presenting an argument to justify the existence of “final causes,” with a focus on answering questions about the biological implications of these causes for evolutionary theory. Then, I attempt to construct two teleological proofs for the existence of God. Finally, I offer some implications of this reasoning for the contemporary disputes over ID/evolution in education.
