Conceiving existence: on Hume’s argument against the distinctness of the idea of existence

There are two questions concerning Hume’s doctrine of existence which have not yet found any persuasive answer: (a) What is his argument in favour of the thesis that there is no distinct idea of existence? (b) What are the semantic and metaphysical consequences of this thesis within his philosophical framework? This paper mainly aims to answer question (a). In order to do that, I will first explain why some reconstructions suggested by interpreters such as Cummins and Bricke are problematic. One of them relies on exegetically dubious presumptions; the other departs too much from Hume’s text. Then, I will offer my own reconstruction that makes maximal use of some principles which are very familiar to Hume’s readers, including the principle stating the similarity between perceptions and their images. After that, I will discuss a potential objection to my reconstruction and make a brief remark on question (b), arguing that, as opposed to numerous interpreters’ concerns, Hume’s thesis that there is no distinct idea of existence does not by itself prevent him from being able to conceive negative existential propositions.

Kant’s Racism

After a long period of comparative neglect, in the last few decades growing numbers of philosophers have been paying attention to the startling contrast presented between Kant’s universal moral theory, with its inspiring enlightenment ideas of human autonomy, equality and dignity and Kant’s racism. Against Charles Mills, who argues that the way to make Kant consistent is by attributing to him a threshold notion of moral personhood, according to which some races do not qualify for consideration under the categorical imperative, I argue that Kant cannot be made consistent on race, and that rather than trying to make him so, we should use the example of Kant’s racism to tell us something about the nature of racism. I argue that Kant’s own moral philosophy and moral psychology in fact give some materials for thinking about his racism, and about racism.     

Kant’s Solution to the Euthyphro Dilemma

Are our actions morally good because we approve of them or are they good independently of our approval? Are we projecting moral values onto the world or do we detect values that are already there? For many these questions don’t state a real alternative but a secular variant of the Euthyphro dilemma: If our actions are good because we approve of them moral goodness appears to be arbitrary. If they are good independently of our approval, it is unclear how we come to know their moral quality and how moral knowledge can be motivating. None of these options seems attractive; the source of moral goodness unclear. Despite the growing literature on Kant’s moral epistemology and moral epistemology the question remains open what Kant’s answer to this apparent dilemma is. The Kantian view I attempt to lay out in this paper is supposed to dissolve the secular version of the Euthyphro dilemma. In responding to this dilemma we need to get clear about the source or the origin of our moral knowledge: Voluntary approval or mind-independent moral facts? Projectivism or detectivism? Construction or given? I believe that all these ways of articulating the problem turn out, on closer inspection, to be false alternatives.     

Kant’s Moral Panentheism

Although Kant is often interpreted as an Enlightenment Deist, Kant scholars are increasingly recognizing aspects of his philosophy that are more amenable to theism. If Kant regarded himself as a theist, what kind of theist was he? The theological approach that best fits Kant’s model of God is panentheism, whereby God is viewed as a living being pervading the entire natural world, present ‘in’ every part of nature, yet going beyond the physical world. The purpose of Kant’s restrictions on our knowledge of God is not to cast doubt on God’s existence, but to preserve a mystery in God’s reality so that God is always more than the world as we experience it. The same God who is theoretically unknowable is also an aspect of the moral substratum of the physical world. Kant’s moral Trinity (God as righteous Lawgiver, benevolent Ruler, and just Judge) permeates everything, as the ultimate unifier of reason and nature. This Paper was delivered during the 2007 APA Pacific Mini-Conference on Models of God, together with papers published in Philosophia 35:3–4.

Finitude and Hume’s Principle

The paper formulates and proves a strengthening of Freges Theorem, which states that axioms for second-order arithmetic are derivable in second-order logic from Humes Principle, which itself says that the number of Fs is the same as the number ofGs just in case the Fs and Gs are equinumerous. The improvement consists in restricting this claim to finite concepts, so that nothing is claimed about the circumstances under which infinite concepts have the same number. Finite Humes Principle also suffices for the derivation of axioms for arithmetic and, indeed, is equivalent to a version of them, in the presence of Freges definitions of the primitive expressions of the language of arithmetic. The philosophical significance of this result is also discussed.     

Kant’s virtue theory

By focusing on human virtues rather than the general morality of rational beings, Kant’s virtue theory presents systematic arguments from the perspectives of reason and experiential emotion, norms and disposition, spirituality and humanity, etc., which is of great significance to an overall understanding of Kantian ethics, thus clarifying misunderstandings from the past decades.     

Kant’s sacrificial turns

This paper addresses the role of the notion of sacrifice in Kant’s theoretical philosophy, practical philosophy, and in his account of religion. First, I argue that kenotic sacrifice, or sacrifice as ‘withdrawal’, plays a hidden and yet important role in the development of Kant’s transcendental philosophy. Second, I focus on Kant’s practical philosophy, arguing that the notion of sacrifice that is both implied and explicitly analyzed by Kant is mainly suppressive sacrifice. However, Kant’s account is fundamentally ambiguous, as sometimes the kenotic meaning of sacrifice seems to resurface, especially in the context of Kant’s discussion of the happiness of others as an end in itself. Because religious notions are regarded by Kant as necessary transitional forms (Darstellungen) to be used to make moral ideas applicable to the world, I then scrutinize Kant’s view of sacrifice as an improper symbol, and I analyze Kant’s arguments for such a dismissal and discuss the subject matter in recent literature. Finally, I examine the role of sacrifice in Kant’s account of Christ as the prototype of pure moral disposition. I conclude by arguing that Kant indeed grasped the importance of including kenotic dynamics in practical philosophy but was somehow unable or unwilling to integrate it into the formal grounding of his ethics. This tension, however, effectively provides an entry point for features that can be found in the post-Kantians.     

Kant’s imitatio Christi

This article retrieves Kant’s imitatio Christi as a viable alternative to the recent construal of mimesis as a universal human desire, in particular to Ward’s reformulation of the imitatio Christi in such terms (in which the human condition is defined by an intrinsic desire for God as other). Kant’s writings participate in a very different debate on imitation (one sceptical of its ethical value), and this plays out as a continual ambivalence towards the concept in his work. Kant’s imitatio Christi, however, does, I contend, make possible a moral form of imitation by characterising it as a rational and intersubjective debate upon the good. Imitating Christ becomes part of human ethical living in the world.

Kant’s Better Man and the Confucian Junzi

This essay attempts to compare Kant’s better man and the Confucian junzi in the Zhongyong, and argues that Kant’s idea of the better man, which expresses human self-improvement in ultimate freedom, is in fact a conception very similar to that of the Confucian junzi, which denotes an ideal human being in cheng. Kant attributes the lack of emphasis on self-improvement in Western culture to the Christian conception of grace, and demonstrates the possibility of self-improvement on the ground of ultimate freedom. We may call this treatment “the Confucian solution” in Kant’s thought. My intention is to explicate the conceptual commonality between the better man and the junzi and demonstrate the Confucian element in Kant’s religious thought.     

Beyond sympathy: Smith’s rejection of Hume’s moral theory

Adam Smith’s Theory of Moral Sentiments (TMS) has long been recognized as importantly influenced by, and in part responding to, David Hume’s earlier ethical theory. With regard to Smith’s account of the foundations of morals in particular, recent scholarly attention has focused on Smith’s differences with Hume over the question of sympathy. Whilst this is certainly important, disagreement over sympathy in fact represents only the starting point of Smith’s engagement with – and eventual attempted rejection of – Hume’s core moral theory. We can see this by recognizing the TMS’s account of moral foundations as predicated upon a rejection of Hume’s distinction between the natural and artificial virtues. Smith is in turn revealed as generating a major break with Hume – a break which, if based on a superior theory of moral foundations (as Smith thought it to be) has important consequences for how we treat Smith and Hume in both the history of philosophy and contemporary moral theory.     

Hume’s Big Brother: counting concepts and the bad company objection

A number of formal constraints on acceptable abstraction principles have been proposed, including conservativeness and irenicity. Hume’s Principle, of course, satisfies these constraints. Here, variants of Hume’s Principle that allow us to count concepts instead of objects are examined. It is argued that, prima facie, these principles ought to be no more problematic than HP itself. But, as is shown here, these principles only enjoy the formal properties that have been suggested as indicative of acceptability if certain constraints on the size of the continuum hold. As a result, whether or not these higher-order versions of Hume’s Principle are acceptable seems to be independent of standard (ZFC) set theory. This places the abstractionist in an uncomfortable dilemma: Either there is some inherent difference between counting objects and counting concepts, or new criteria for acceptability will need to be found. It is argued that neither horn looks promising.

Nonconceptualism,Hume’s Problem,and the Deduction

Lucy Allais seeks to provide a reading of the Transcendental Deduction of the Categories which is compatible with a nonconceptualist account of Kant’s theory of intuition. According to her interpretation, the aim of the Deduction is to show that a priori concept application is required for empirical concept application. I argue that once we distinguish the application of the categories from the instantiation of the categories, we see that Allais’s reconstruction of the Deduction cannot provide an answer to Hume’s problem about our entitlement to use a priori concepts when thinking about the objects of empirical intuition. If the Deduction is to provide a response to Hume, Allais’s interpretation must be rejected.
