William of Ockham (d. 1347) is well known for his commitment to parsimony and for his so-called ‘razor’ principle. But little is known about attempts among his own contemporaries to deflect his use of the razor. In this paper, I explore one such attempt. In particular, I consider a clever challenge that Ockham’s younger contemporary, Walter Chatton (d. 1343) deploys against the razor. The challenge involves a kind of dilemma for Ockham. Depending on how Ockham responds to (...) this dilemma, his razor will, Chatton argues, either prove unacceptably dull when it comes to determining ontological commitment or prove unacceptably sharp when it comes to determining commitments entailed by certain theological doctrines. While Chatton’s objection is subtle and interesting in its own right, the broader significance of the debate between these thinkers lies in the light it sheds on medieval approaches to issues surrounding metaphysical methodology.

It is sometimes claimed that the Bayesian framework automatically implements Ockham’s razor—that conditionalizing on data consistent with both a simple theory and a complex theory more or less inevitably favours the simpler theory. It is shown here that the automatic razor doesn’t in fact cut it for certain mundane curve-fitting problems.

In Ockham's Razors: A User's Guide, Elliott Sober argues that parsimony considerations are epistemically relevant on the grounds that certain methods of model selection, such as the Akaike Information Criterion, exhibit good asymptotic behaviour and take the number of adjustable parameters in a model into account. I raise some worries about this form of argument.

This paper discusses Kevin Kelly’s recent attempt to justify Ockham’s Razor in terms of truth-finding efficiency. It is argued that Kelly’s justification fails to warrant confidence in the empirical content of theories recommended by Ockham’s Razor. This is a significant problem if, as Kelly and many others believe, considerations of simplicity play a pervasive role in scientific reasoning, underlying even our best tested theories, for the proposal will fail to warrant the use of these theories in practical prediction.

William of Ockham seems to have endorsed the view (i) that a whole is its parts, (ii) that some things are such that whether they together compose a whole is contingent, and (iii) that parts are ontologically prior to the whole they compose. Ockhamist Composition as Identity is the conjunction of these three claims. It seems doubly absurd since Leibniz’s Law arguments can be run against both the conjunction of (i) and (ii) and that of (i) and (iii). In this (...) article, I appeal to recent developments in counterpart theory to block these arguments and adequately interpret the Ockhamist version of the view that composition is identity.

One version of moral error theory maintains that the central problem with morality is an ontological commitment to irreducible normativity. This paper argues that this version of error theory ultimately depends on an appeal to Ockham’s Razor, and that Ockham’s Razor should not be applied to irreducible normativity. This is because the appeal to Ockham’s Razor always contains an intractable element of epistemic circularity; and if this circularity is not vicious, we can construct a sound argument for (...) the existence of irreducibly normative truths that contains a similar kind of epistemic circularity. This argument is a version of Pascal’s Wager which I call “Parfit’s Wager,” because it is based on a passage from Derek Parfit’s On What Matters. It states that, if we believe that there are some irreducibly normative truths, we are more likely to be believing what we ought to believe compared to not believing that there are such truths, and that this indicates that we ought rationally to believe that there are such truths, justifying the ontological commitment to irreducible normativity in the process.

This paper discusses the role that appeals to theoretical simplicity have played in the debate between nativists and empiricists in cognitive science. Both sides have been keen to make use of such appeals in defence of their respective positions about the structure and ontogeny of the human mind. Focusing on the standard simplicity argument employed by empiricist-minded philosophers and cognitive scientists—what I call “the argument for minimal innateness”—I identify various problems with such arguments—in particular, the apparent arbitrariness of the relevant (...) notions of simplicity at work. I then argue that simplicity ought not be seen as a theoretical desideratum in its own right, but rather as a stand-in for other desirable features of theories. In this deflationary vein, I argue that the best way of interpreting the argument for minimal innateness is to view it as an indirect appeal to various potential biological constraints on the amount of innate structure that can wired into the human mind. I then consider how nativists may respond to this biologized version of the argument, and discuss the role that similar biological concerns have played in recent nativist theorizing in the Minimalist Programme in generative linguistics.

on ). Advice about how to move forward on the mindreading debate, particularly when it comes to overcoming the logical problem, is much needed in comparative psychology. In chapter 4 of his book Ockham’s Razors, Elliott Sober takes on the task by suggesting how we might uncover the mechanism that mediates between the environmental stimuli that is visible to all, and chimpanzee social behavior. I argue that Sober's proposed method for deciding between the behaivor-reading and mindreading hypotheses fails given the (...) nature of each of those hypotheses. I argue that the behavior-reading hypothesis that Povinelli and colleagues propose is so rich and robust that it is going to make predictions that are behaviorally indiscernible from the mindreading hypothesis. Further, I argue that the logical problem artificially separates one’s knowledge of behavior and one’s knowledge of mind. If we reject this form of dualism, the logical problem doesn’t arise.

CATEGORY: Philosophy play; historical fiction; comedy; social criticism. -/- STORYLINE: Tim, a physics professor with a certain taste for young female university students, recently got a new appointment at a London university. But, as it turns out, he is still unsatisfied. Why? Is it because Rachael unexpectedly left him under strange circumstances? Or does it have to do with his sudden departure from another university? Or is it his research? When Tim meets Christianus for a brown-bag discussion on philosophy and (...) science, new facts and perspectives are revealed. -/- TOPICS: In the course of the play, Tim and Christianus discuss different metaphysical, epistemological, and ontological ideas. Many of these are either related to isssues in the philosophy of science (explanation, methodology, scientific investigation, etc.), or to issues in human psychology and the philosophy of mind (the self vs. the mind, dualism, ‘Who am I?’, etc.). In one scene, for example, Tim tries to invoke ‘Ockham’s Razor’ (or ‘Occam’s Razor’) to quickly dismiss some of Christianus’s metaphysical ideas (see Scene VII: Ockham’s Raisin; Scene XIII: The Raisin Tale Revisited); in another scene, Christianus introduces his ‘Postman’ scenario, and the idea that successful (‘scientific’) prediction or forecasting is not necessarily a sure sign of true understanding (see Scene XV: The Postman Always Turns Twice). -/- NOTES: This work features elaborate footnotes and comments (including full bibliographical references) by the author, to enhance the reader's experience of the play and its philosophizing characters.

Uno de los principales criterios que utiliza el método científico para establecer la pertinencia de una explicación o hipótesis competidora con respecto a un evento en la realidad física, es el principio de simplicidad o parsimonia científica. Este suele implicar la prescindencia de entidades o hipótesis consideradas innecesarias para la explicación de un fenómeno. Las raíces de este principio se suelen trazar hasta el filósofo nominalista medieval Guillermo de Ockham. En el presente trabajo, se pretende determinar el posible impacto de (...) la concepción metodológica derivada de la Navaja de Ockham en torno a la hipótesis cosmológica de los multiversos, y realizar un recorrido por la visión crítica del cosmólogo, George F.

Moral subjectivism is not self-defeating, contrary to what moral objectivists claim. Ockham’s Razor favors moral subjectivism over moral objectivism. It is circular for moral objectivists to say that since we construct sound and cogent arguments out of moral statements, moral statements are true. Moral subjectivism acknowledges the role that arguments play in our moral lives, contrary to what moral objectivists contend. The way in which moral objectivists attempt to establish moral objectivism ironically supports moral subjectivism.

In diesem Eintrag werden zwei miteinander zusammenhängende Aspekte betrachtet. Nun betreffen diese zwei Aspekte aber nicht ontologische Fragen erster Ordnung, d. h. Fragen, was es gibt. Vielmehr sind es Fragen zweiter Ordnung, ›metaontologische‹ Fragen dazu, wie philosophisch untersucht werden sollte, was es gibt. Der Fokus dieses Eintrags liegt dabei auf der Standardauffassung ontologischer Untersuchung, die die philosophische Literatur der letzten Jahre dominiert hat. Diese Auffassung haben wir zum größten Teil dem Einfluss von Willard Van Orman Quine zu verdanken.

McKitrick (2003) proposes that an object has a disposition if and only if there are a manifestation, the circumstances of the manifestation, a counterfactual true of the object, and an overtly dispositional locution referring to the disposition. A disposition is extrinsic if and only if an object has it, but a perfect duplicate of the object might not have it. I present an alternative definition that an object has a disposition if and only if a counterfactual is true of the (...) object that under a certain condition, it would interact with another object in a certain manner. There are three reasons for thinking that my definition is better than her definition. 1. Ockham’s razor favors my definition over McKitrick’s definition. My definition is consistent, while her definition is not, with Lewis’s and her definitions of intrinsic and extrinsic properties. 3. My definition goes well, while her definition does not, with our intuition that an object has a disposition even in a possible world where there is nothing but that object. (shrink)

Many metaphysicians often appeal to Hume’s dictum (HD), according to which there are no necessary connections between distinct entities (or states of entities), in order to resist theories that commit us to such connections. Some have argued that HD is an unsupported dogma of metaphysics. But theories that commit us to necessary connections between distinct goings-on can also be resisted by invoking a normative twist on HD, which I call the Humean Solvent (HS): “Do not connect distinct entities (or states (...) of entities) beyond necessity”. HS is a principle of structural parsimony – assuming that a theory is structurally more parsimonious than another when the latter is committed to a more connected ontology than the former is. Just as Ockham’s ‘razor’ encourages us to cut down superfluous ontological commitments, the Humean ‘solvent’ encourages us to dissolve dispensable metaphysical glue: we ought not to glue elements of our ontology beyond necessity. HS has both a qualitative and a quantitative dimension: qualitatively, it encourages us to avoid using metaphysical glues that are unnecessarily strong, the strongest of which being metaphysically necessary connections; quantitatively, it encourages us not to metaphysically glue things that need no gluing. Thus, given HS, other things being equal, what is worst is a theory that entails that everything is metaphysically necessarily connected to anything else and what is best is a theory that leaves all things loose and separable. In this paper, I will first compare HD and HS as grounds for paradigmatic Humean doctrines in contemporary metaphysics, then I will argue that structural parsimony is neither a variety of ontological nor of ideological parsimony; finally, I will offer an argument for HS.

Cornea (2012) argues that I (2011) was wrong to use the analogy between morality and motion to defend cultural relativism. I reply that the analogy can be used to clarify what cultural relativism asserts and how a cultural relativist can reply to the criticisms against it. Ockham’s Razor favours the relativist view that there are no moral truths, and hence no culture is better than another. Contrary to what Cornea claims, cultural relativism does not entail that we cannot protect (...) ourselves from those who attack us, and that the ruling of an international court lacks moral legitimacy.

Sometimes philosophers have been misunderstood. It could be because the philosopher's communication was vague. It could also be because the philosopher didn't use Ockham's razor and multiplied terms unnecessarily forcing reviewers to impose the razor, with the result that what needs to be cut is not cut and what was essential is taken out of the equation. This article cites two cases, one of the Indian thinker M.M. Thomas and other of Peter Van Inwagen, who claimed that (...) their thoughts were misrepresented by some other well known thinker.

The distinction between the semantic content of a sentence or utterance and its use is widely employed in formal semantics. Semantic minimalism in particular understands this distinction as a sharp dichotomy. I argue that if we accept such a dichotomy, there would be no reason to posit the existence of semantic contents at all. I examine and reject several arguments raised in the literature that might provide a rationale for assuming semantic contents, in this sense, exist, and conclude that Ockham’s (...) razor should be applied to these postulated entities. Since the notion of “semantic content” doubles both as what a semantic theory is a priori supposed to account for and as the product of that same theory, it is methodologically unsound to appeal to this notion to fend off criticisms of and counterexamples to semantic theories.

The framework of Solomonoff prediction assigns prior probability to hypotheses inversely proportional to their Kolmogorov complexity. There are two well-known problems. First, the Solomonoff prior is relative to a choice of Universal Turing machine. Second, the Solomonoff prior is not computable. However, there are responses to both problems. Different Solomonoff priors converge with more and more data. Further, there are computable approximations to the Solomonoff prior. I argue that there is a tension between these two responses. This is because computable (...) approximations to Solomonoff prediction do not always converge. (shrink)

Agnosticism has had some bad press in recent years. Nonetheless, I hope to show that agnosticism can be so formulated that it is no less philosophically respectable than theism and atheism. This is not a mere philosophical exercise; for, as it happens, the formulated position is--I think--the one to which I subscribe. I include a qualification here since it may be that the position to which I subscribe is better characterised as fallibilist atheism--but more of that anon.

In the present paper, our objective is to examine the application of belief revision models to scientific rationality. We begin by considering the standard model AGM, and along the way a number of problems surface that make it seem inadequate for this specific application. After considering three different heuristics of informational economy that seem fit for science, we consider some possible adaptations for it and argue informally that, overall, some paraconsistent models seem to better satisfy these principles, following Testa (2015). (...) These models have been worked out in formal detail by Testa, Cogniglio, & Ribeiro (2015, 2017). (shrink)

Let’s consider the skeptical example of the brain in a vat. It has been pointed out by Crispin Wright (1994) that Putnam's argument does not affect certain cases such as my brain being removed from my skull by a mad scientist and hooked up to a computer. Since Putnam's argument falls flat at least in cases where the brain is first removed from a human body and then hooked up to a computer, I consider the skeptical aspects of the brain-in-a-vat (...) thought experiment below. Let’s consider the following hypotheses: C “I’m a brain in a vat” EC “I’m not a brain in a vat”. It is argued by skeptics that it cannot be proven that we are not brains in a vat. If we assume the skeptical thesis according to which it is impossible to prove that we are not brains in a vat, i.e. there is the impossibility of falsifying C, then the truthfulness of EC implies that both C and EC can not be falsified. On the other hand, the truthfulness of C does not imply the unfalsifiability of EC: for example, the mad scientist mentioned above could decide (perhaps for a sadistic pleasure) to inform us and prove to us that we are brains in a vat; in the latter case the EC hypothesis would be falsified. The truthfulness of EC implies the unfalsifiability of both EC and C. By contrast, the truthfulness of C does not imply the unfalsifiability of EC. The current evidence is that both C and EC are not falsified: the hypothesis EC necessarily implies that both EC and C result not falsified; the hypothesis C does not necessarily imply that both C and EC result not falsified And so, it is more rational to bet on EC rather than on C.

Detecting quality in large unstructured datasets requires capacities far beyond the limits of human perception and communicability and, as a result, there is an emerging trend towards increasingly complex analytic solutions in data science to cope with this problem. This new trend towards analytic complexity represents a severe challenge for the principle of parsimony (Occam’s razor) in science. This review article combines insight from various domains such as physics, computational science, data engineering, and cognitive science to review the specific (...) properties of big data. Problems for detecting data quality without losing the principle of parsimony are then highlighted on the basis of specific examples. Computational building block approaches for data clustering can help to deal with large unstructured datasets in minimized computation time, and meaning can be extracted rapidly from large sets of unstructured image or video data parsimoniously through relatively simple unsupervised machine learning algorithms. Why we still massively lack in expertise for exploiting big data wisely to extract relevant information for specific tasks, recognize patterns and generate new information, or simply store and further process large amounts of sensor data is then reviewed, and examples illustrating why we need subjective views and pragmatic methods to analyze big data contents are brought forward. The review concludes on how cultural differences between East and West are likely to affect the course of big data analytics, and the development of increasingly autonomous artificial intelligence (AI) aimed at coping with the big data deluge in the near future.

Occam’s razor is frequently considered to be a cornerstone of the scientific method. Indeed, it was and remains a valuable tool for scientific and philosophical inquiry. However, we provided an overview of some historical instances in which it led science away from a reasonable and sound heuristic approach. Some words of caution are necessary to clarify how, contrary to common belief, a too strict adherence to such a principle did not guarantee scientific rigor but, rather, obstructed further progress.

“Never attribute to malice that which is adequately explained by stupidity”—so says Hanlon’s Razor. This principle is designed to curb the human tendency toward explaining other people’s behavior by moralizing it. We ask whether Hanlon’s Razor is good or bad advice. After offering a nuanced interpretation of the principle, we critically evaluate two strategies purporting to show it is good advice. Our discussion highlights important, unsettled questions about an idea that has the potential to infuse greater humility and (...) civility into discourse and debate. (shrink)

William Ockham held that, in addition to written and spoken language, there exists a mental language, a structured representational system common to all thinking beings. Here I present and evaluate an argument found in several places across Ockham's corpus, wherein he argues that positing a mental language is necessary for the nominalist to meet certain ontological constraints imposed by Aristotle’s account of scientific demonstration.

It is well-known that Chatton is among the earliest and most vehement critics of Ockham’s theory of judgment, but scholars have overlooked the role Chatton’s criticisms play in shaping Ockham’s final account. In this paper, I demonstrate that Ockham’s most mature treatment of judgment not only contains revisions that resolve the problems Chatton identifies in his earlier theories, but also that these revisions ultimately bring his final account of the objects of judgment surprisingly close to Chatton’s own. Even so, I (...) argue that, at the end of the day, there remain significant differences between their respective analyses of the structure and intentionality of judicative states. (shrink)

Elizabeth Karger has suggested an interpretation of Ockham's theory of the modes of common personal supposition ("TM") according to which the purpose of TM is to provide certain distinctions that Ockham will use in formulating a unified theory of immediate inference among certain kinds of sentences. Karger presents a single, powerful rule of inference that incorporates TM distinctions and that is meant to codify Ockham's theory of immediate inference. I raise an objection to Karger's rule, thereby calling into (...) doubt the interpretation of Ockham that is based on attributing that rule to him. (shrink)

We lay out the fatalist’s argument, making sure to clarify which dialectical moves are available to the libertarian. We then offer a more robust presentation of Ockhamism, responding to obvious objections and teasing out the implications of the view. At this point, we discuss presentism and eternalism in more detail. We then present our argument for the claim that the libertarian cannot take Ockham’s way out of the fatalism argument unless she rejects presentism. Finally, we consider and dispense with objections (...) to our argument. In the end, it ought to be clear that the libertarian must make a choice between Ockham’s way out and presentism. (shrink)

Certain non-voluntarists have recently defended political authority by advancing two-part views. First, they argue that the state, or the law, is best (or uniquely) capable of accomplishing something important. Second, they defend a substantive normative principle on which being so situated is sufficient for de jure authority. This paper uses widely accepted tenets to show that all such defenses of authority fail.

This paper reconsiders Ockham's critique of the species theory of cognition. As Ockham understands this theory, it says that the direct objects of cognition are mental representations, or species. According to many commentators, one of Ockham's main objections to this theory was that, if the direct objects of cognition are species rather than external objects, we will never be able to establish whether or not a given species is a veridical representation of the world. In this paper I (...) argue that this line of interpretation sits uneasily with Ockham's epistemology, and offer a new interpretation of Ockham's critique of species. (shrink)

According to Grice's “Modified Occam's Razor”, in case of uncertainty between the implicature account and the polysemy account of word uses it is parsimonious to opt for the former. However, it is widely agreed that uses can be partially conventionalised by repetition. This fact, I argue, raises a serious problem for MOR as a methodological principle, but also for the substantial notion of implicature in lexical pragmatics. In order to overcome these problems, I propose to reinterpret implicatures in terms (...) of implicature-like effects delivered by non-inferential processes. (shrink)

Among the most widely discussed of William of Ockham’s texts on ethics is his Quodlibet III, q. 14. But despite a large literature on this question, there is no consensus on what Ockham’s answer is to the central question raised in it, specifically, what obligations one would have if one were to receive a divine command to not love God. (Surprisingly, there is also little explicit recognition in the literature of this lack of consensus.) Via a close reading of the (...) text, I argue, contrary to much of the literature, that Ockham believes that if one were given this command, one would be obligated to refrain from loving God and would also be able to fulfill this obligation without any moral wrongdoing. Among other results, this study will help clarify Ockham’s much-discussed claim that loving God is “a necessarily virtuous act.”. (shrink)

This paper attempts to demonstrate that the logical problematic of signification, has a very dangerous socio-political effect due to the ontological implication that is connected to the signification of terms in logic. It expounds the notion of signification in Formal Logic as exposed by William of Ockham. It thus, employs this notion of signification of terms, to discuss the term “Fulani”, to show the danger potent in distorting the signification of the term “Fulani” as in every conventional and connotative terms. (...) This work claims that as a result of the connection between logic and ontology, conceptualization and perception, names and reality, the distortion of terms, which are the building blocks of propositions in logic could lead to a dangerous cognition and perception of ontological realities. To this end, it posits a critique on the dangerous change in the signification of the term “Fulani”, in the conceptualization and perception of present day Nigeria people, of West Africa. A dangerous change, as this paper claims, if not speedily reconstructed and re-conceptualized, could lead to a disastrous situation in the socio-political reality of the Nigerian State. (shrink)

The Razor says: do not multiply entities without necessity! The Laser says: do not multiply fundamental entities without necessity! Behind the Laser lies a deep insight. This is a distinction between the costs and the commitments of a theory. According to the Razor, every commitment is a cost. Not so according to the Laser. According to the Laser, derivative entities are an ontological free lunch: that is, they are a commitment without a cost. Jonathan Schaffer (2015) has argued (...) that the Laser should replace the Razor. In Sections 2-4 we shall discuss and argue against Schaffer’s arguments for replacing the Razor with the Laser. Schaffer considers several objections to his views, and in Sections 5-7 we shall argue that Schaffer does not deal successfully with two of them. In Section 8 we shall present a probabilistic argument for the Laser. However, the argument has a limitation and does not support the replacement of the Razor with the Laser. Indeed, it supports only the claim that, given certain assumptions, the multiplication of explanatorily relevant derivative entities does not matter; but, as we argue in the same section, there is an argument that multiplying explanatorily superfluous derivative entities does makes a theory less rationally acceptable. Our conclusion is that the Laser cannot replace the Razor and that derivative entities are not an ontological free lunch. (shrink)

This paper explores William Ockham's account of memory with a view to understanding its implications for his account of the nature and persistence of human beings. I show that Ockham holds a view according to which memory (i) is a type of self-knowledge and (ii) entails the existence of an enduring psychological subject. This is significant when taken in conjunction with his account of the afterlife. For, Ockham holds that during the interim state—namely, after bodily death, but prior to (...) bodily resurrection—we retain and recall our embodied experiences. This entails that the subject of our embodied psychological states can survive in a disembodied state and continue to engage in characteristic rational activities—a claim that appears to run against Ockham's own commitment to a hylomorphic conception of human beings (as essentially material). A central aim of this paper is to explore the prospects for reconciling Ockham's account of interim memory with his account of human beings. (shrink)

Ockham holds what nowadays would be characterized as a “higher-order perception” theory of consciousness. Among the most common objections to such a theory is the charge that it gives rise to an infinite regress in higher-order states. In this paper, I examine Ockham’s various responses to the regress problem, focusing in particular on his attempts to restrict the scope of consciousness so as to avoid it. In his earlier writings, Ockham holds that we are conscious only of those states to (...) which we explicitly attend. This view, I go on to argue, is inadequate on both phenomenological and philosophical grounds. Interestingly, and perhaps for this very reason, in later works, Ockham goes on to develop an alternative explanation for his account of the limited scope of consciousness. (shrink)

In this paper I examine William Ockham’s theory of judgment and, in particular, his account of the nature and ontological status of its objects. Commentators, both past and present, habitually interpret Ockham as defending a kind of anti-realism about objects of judgment. My aim in this paper is two-fold. The first is to show that the traditional interpretation rests on a failure to appreciate the ways in which Ockham’s theory of judgment changes over the course of his career. The second, (...) and larger, aim is to show that careful attention to these changes in Ockham’s account (and to the motivations for them) sheds new light on broader developments in his philosophy of mind—specifically, on his views about the nature of concepts and on his account of the nature and structure of intentionality itself. (shrink)

The focus of this paper is Ockham's stance on the question of divine concurrence---the question whether God is causally active in the causal happenings of the created world, and if so, what God's causal activity amounts to and what place that leaves for created causes. After discussing some preliminaries, I turn to presenting what I take to be Ockham's account. As I show, Ockham, at least in this issue, is rather conservative: he agrees with the majority of medieval (...) thinkers (including Aquinas, Giles of Rome, Duns Scotus, and others) that both God and created agents are causally active in the causal happenings of the world. Then I turn to some texts that may suggest otherwise; I argue that reading Ockham as either an occasionalist or a mere conservationist based on these texts originates from a misunderstanding of his main concern. I conclude with raising and briefly addressing some systematic worries regarding Ockham's account of concurrence. (shrink)

Aristotle and William of Ockham both argue that existence or being is a predicate, though not a distinguishing predicate. I place Ockham’s argument in an Aristotelian context and discuss its merits. I then turn to empiricist criticisms of the view that we can coherently predicate being of things. I argue that while Ockham’s argument is cogent, his account of how we come to have the concept of being is inadequate. Ockham’s view needs to be supplemented with Kantian insights.

Truth is a key notion in Ockham’s philosophical reductionist program, a notion that has been the object of contrasting interpretations in scholarship. My interpretation is that, for Ockham, ‘being true’ expresses an epistemological relation, namely the one through which our mind reflects on a proposition of language, compares it with an extra-mental state of affairs, and thus ascertains their correspondence. Placing truth at a point of intersection of language with mind and reality, Ockham’s interpretation of Aristotle’s characterization of philosophy as (...) the science of truth comes to be innovative. For Ockham, philosophy is a meticulous training of interpretation of language in order to account correctly for the truth-value of propositions. (shrink)

In this paper I challenge recent externalist interpretations of Ockham’s theory of intuitive cognition. I begin by distinguishing two distinct theses that defenders of the externalist interpretation typically attribute to Ockham: a ‘direct reference thesis’, according to which intuitive cognitions are states that lack all internal, descriptive content; and a ‘causal thesis’, according to which intuitive states are wholly determined by causal connections they bear to singular objects. I then argue that neither can be plausibly credited to Ockham. In particular, (...) I claim that the causal thesis doesn’t square with Ockham’s account of supernaturally produced intuition and that the direct reference thesis sits uneasily with Ockham’s characterization of the intentional structure of intuitive states. (shrink)

In this essay, we reconsider two themes particularly discussed by the interpreters of Ockham: that of divine omnipotence and the hypothesis of the intuitive cognition of non-existent things. The purpose is to show that the hypothetical case considered by Ockham was subjected to opposite interpretations. For theological reasons, Ockham attributes not only to God but also to human beings the possibility of having acts of intuitive cognition of things that do not exist; nonetheless, he holds that it is contradictory for (...) God to give us the evident cognition of things that appear to be present when they are actually absent. Walter Chatton opposes this conclusion, arguing that no contradiction ensues from that hypothesis. Instead, he believes that it is impossible for God to give us the intuition of things that absolutely do not exist or are in no way present to us. Ockham’s arguments include some difficulties that Chatton acutely sees and discusses. In particular, Chatton calls into question Ockham’s missed distinction between the existence and the presence of the intuited thing. (shrink)

This article investigates the relation between the will and evil in Ockham’s thought. The main purpose is to show to what extent the deliberate and conscious will of evil (velle malum sub ratione mali) is possible according to Ockham’s psychological and metaethical assumptions.

The Ockhamist claims that our ability to do otherwise is not endangered by God’s foreknowledge because facts about God’s past beliefs regarding future contingents are soft facts about the past—i.e., temporally relational facts that depend in some sense on what happens in the future. But if our freedom, given God’s foreknowledge, requires altering some fact about the past that is clearly a hard fact, then Ockhamism fails even if facts about God’s past beliefs are soft. Recent opponents of Ockhamism, including (...) David Widerker and Peter van Inwagen, have argued along precisely these lines. Their arguments, if successful, would undermine Ockhamism while avoiding the controversy over the alleged softness of facts about God’s past beliefs. But these arguments do not succeed. The past facts they rely on must be clear and uncontroversial examples of hard facts about the past, and these facts must be such that an ability to refrain from the relevant future action implies an ability to alter the relevant hard fact. We demonstrate the flaw in these arguments by showing how they rely on past facts that do not satisfy these criteria. The Ockhamist may have troubles, but this type of argument is not one of them.

On the dominant interpretation, Ockham is an externalist about mental content. This reading is founded principally on his theory of intuitive cognition. Intuitive cognition plays a foundational role in Ockham’s account of concept formation and judgment, and Ockham insists that the content of intuitive states is determined by the causal relations such states bear to their objects. The aim of this paper is to challenge the externalist interpretation by situating Ockham’s account of intuitive cognition vis-à-vis his broader account of efficient (...) causation. While there can be no doubt that intuitive states are causally individuated, I argue that, given Ockham’s broader theory of efficient causation (on which causation turns out to be an internal relation), this very fact entails that the content of such states is determined by factors internal (rather than external) to the states themselves.

This article focuses on one aspect of the late mediaeval debate over divine power, as it was discussed by Oxford philosophers Walter Chatton (d. 1343) and William Ockham (d. 1347). Chatton and Ockham would have agreed, for example, that God is ultimately responsible for the existence of the works of Pablo Picasso, but they would not agree over wheher it violates God's omnipotence to say that he cannot make something that Picasso made, for example, the painting Guernica, without using Picasso (...) himself as an intermediate cause. The context of their dispute was a larger debate regarding the ontological status of relations. This article (1) explains how these two issues, omnipotence and relations, became so interestingly tangled together, (2) tries to see which of the two men mentioned above got the better of their exchange, and finally (3) draws out some important consequences for fourteenth-century discussions of causality, occasionalism, and omnipotence.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:The Cambridge Companion to OckhamJeffrey E. BrowerPaul Vincent Spade, editor. The Cambridge Companion to Ockham. Cambridge: Cambridge University Press, 1999. Pp. xii + 400. Cloth, $54.95.Contemporary analytic philosophers have always been among the most enthusiastic audiences for the volumes in the Cambridge Companion series. And of all the great philosophers of the Middle Ages, perhaps none has appealed more to their sensibilities than William Ockham. It is fitting, (...) therefore, that after the publication of the Companion to Aquinas—the first volume in the series devoted to a medieval philosopher—there should appear a Companion to Ockham.The fifteen chapters comprising this volume survey the entire range of Ockham's thought and may conveniently be divided into four main parts. The first part (chaps. 2-7) deals with Ockham's most enduring legacy: his contribution to issues falling within the domain of logic, philosophy of language, and metaphysics. The second part (chaps. 8-9) is devoted to issues in epistemology and philosophy of mind/cognition. The third part (chaps. 10-13) focuses on Ockham's views in ethics, action theory, and political philosophy. And the fourth part (chaps. 14-15) considers aspects of his philosophical theology. In addition, there is also an historical chapter (chap. 1), placing Ockham's life and works in their late-medieval intellectual context, and a brief editor's introduction, including a very useful list of all Ockham's writings, together with the best (sometimes, the only) Latin editions and English translations available.The volume is well organized and beautifully conceived. Some chapters are quite difficult, and in places contain material that is likely to be unfamiliar even to specialists in medieval philosophy. But the way in which they have been organized maximizes their usefulness and accessibility to specialists and non-specialists alike. The earlier parts of the volume lay the foundation for later ones, and the individual chapters within each part are arranged so as to build on and complement one another. This is perhaps most evident in the five chapters comprising the first part. Calvin Normore's presentation ofOckham's logic (in chap. 2) nicely prepares the reader for Claude Panaccio's discussion (in chap. 3) of Ockham's theory of mental language. Panaccio's chapter, in turn, provides the framework for David Chalmer's analysis (in chap. 4) of the debate over whether [End Page 588] Ockham's mental language permits synonymous expressions. Again, these three chapters taken together provide important background for Paul Spade's treatment (in chap. 5) of Ockham's views in metaphysics, which are closely related to his logic and philosophy of language. Finally, Gyula Klima's discussion (in chap. 6) ofhow Ockham's views in semantics and ontology differ from those of his predecessors, and André Goddu's discussion (in chap. 7) of Ockham's philosophy of nature, can be fully appreciated only against the background of the preceding chapters.What is perhaps most impressive about the volume, however, is the extent to which it succeeds at providing a systematic introduction to Ockham's philosophical achievement. All the chapters are, to some extent, concerned with matters of textual analysis and interpretation. But most of them involve much more than a mere survey of Ockham's texts. For example, in each of the four main parts, there is at least one chapter that attempts to locate Ockham's views in relation to those of his predecessors or contemporaries (such as Aquinas and Scotus), with the result that we get a sense of Ockham's place in the major medieval debates to which he contributed. At the same time, the volume introduces us to some of the most lively current debates in Ockham scholarship. It does this, not merely by summarizing them, but by actually carrying them out over the course of its chapters. For example, Eleonore Stump provides a sophisticated defense (in chap. 8) of what has become a standard interpretation of Ockham's theory of intuitive and abstractive cognition. In the following chapter, however, Elizabeth Karger rejects the standard interpretation on the basis of a re-reading of certain key texts. Again, in the first part of the volume there is a running debate... (shrink)

This paper argues in the first place that nominalists are right in insisting against ontological realists that semantic universality does not require commitment to universal entities. However, Ockham, in his zeal to get rid of Scotus’s universal entities, swept under the carpet the issue of universal representational content of genuinely universal symbols, conflating it with the mere indifference of the information content of non-distinctive singular representations. Buridan did come up with an abstractionist theory of the formation of genuinely universal representational (...) content to solve the resulting issues, however, the paper argues further, his solution is committed to attributing the sort of “aspectuality” to universal absolute concepts that his Ockhamist semantics denies to them. The conclusion of the paper suggests how Aquinas’s “moderate realism” can provide a consistent solution without the ontological extravaganza of ontological realists, without conflating the mere indifference of singular representation with genuine universality, and without having to deny aspectuality to our quidditative universal concepts formed by abstraction.
