Metaphysics and ethics are two distinct fields in academic philosophy. The object of metaphysics is what is, while the object of ethics is what ought to be. Necessitarianism is a modal doctrine that appears to obliterate this neat distinction. For it is commonly assumed that ought (at least under normal circumstances) implies can. But if necessitarianism is true then I can only do what I actually do. Hence what I ought to do becomes limited to what I in fact do. (...) This is one widespread way of construing the danger that necessitarianism poses for ethics. There is, however, another way in which this collapse of what is with what ought to be can be construed. One could think of what is as already being what ought to be, of the two being one. On this picture, everything that is, is already valuable. In this thesis I explore the theory that being is intrinsically valuable. I do so by investigating the philosophy of perfection present in the works of the early modern rationalist Spinoza. For in his philosophy of perfection, I argue, we find being and value to be perfectly aligned. Hence, my reading challenges a widespread interpretation, according to which (ontological) perfection is divested of normativity in Spinozism. The position that all being is intrinsically valuable since it is perfect may be thought to be incompatible with human perfectionism. For what room can there be for human progress toward an ideal of perfection if all that exists, is necessarily perfect? The goal of the thesis is to respond to this question by providing a systematic interpretation of the metaphysics of human perfectibility in Spinoza’s philosophy. In order to achieve this goal, I undertake two tasks. First, I examine Spinoza’s multi-faceted philosophy of perfection. I distinguish between ontological and teleological perfection. Moreover, I argue that since Spinoza maintains that everything is perfect to the extent that it is, perfection shoulders the role of a transcendental within his system. In order to highlight the normative significance of transcendental perfection, I compare Spinoza’s thought with the transcendental theory of the good in Thomas Aquinas. In addition, I distinguish between ontological and speculative perfection. Speculative perfection is conscious awareness of ontological perfection. Second, I show how infinity plays an essential role in Spinoza’s ethics by indicating how we, by availing ourselves of this notion, are able to acquire a perspective on reality from which its ontological perfection may be discovered. On this basis, I am able to demonstrate the (relatively understudied) ethical and soteriological importance of Spinoza’s conception of infinity. I argue that it is because (a) Spinoza’s ideal of human perfection is speculative, and because (b) one will be able to establish the (ontological) perfection of things by deducing it from the divine essence only when one considers this essence absolutely infinite, that (c) the absolute infinity of the divine essence plays a significant role in Spinoza’s account of human perfection as consisting in conscious awareness of the value of all being.

This paper explores the theory of freedom that Emilie du Châtelet advances in her essay “On Freedom.” Using contemporary terminology, we can characterize this theory as a version of agent-causal compatibilism. More specifically, the theory has the following elements: (a) freedom consists in the power to act in accordance with one’s choices, (b) freedom requires the ability to suspend desires and master passions, (c) freedom requires a power of self-motion in the agent, and (d) freedom is compatible with moral necessity (...) but not with physical necessity. While these elements may at first appear disparate, the paper shows that they fit together quite well. The resulting theory is a surprising combination of doctrines that appear to be based on Samuel Clarke’s libertarian account of free will and doctrines that are reminiscent of the compatibilist accounts of John Locke, Anthony Collins, Gottfried Leibniz, and Thomas Hobbes.

In his essay against Eberhard, Kant denies that there are innate concepts. Several scholars take Kant’s statement at face value. They claim that Kant did not endorse concept innatism, that the categories are not innate concepts, and that Kant’s views on innateness are significantly different from Leibniz’s. This paper takes issue with those claims. It argues that Kant’s views on the origin of the intellectual concepts are remarkably similar to Leibniz’s. Given two widespread notions of innateness, the dispositional notion and (...) the input/output notion, intellectual concepts are innate for Kant no less than for Leibniz. (shrink)

Gottfried Wilhelm Leibniz endorses a version of the guise of the good thesis: he holds that whenever we do something intentionally, we do it because it seems good to us. This paper explores Leibniz...

In a series of publications, L. A. Paul has defended a version of the bundle theory according to which material objects are nothing but mereological sums of ‘their’ properties. This ‘mereological’ bundle theory improves in important ways on earlier bundle theories, but here I present a new argument against it. The argument is roughly this: Material objects occupy space; even if properties have spatial characteristics, they do not quite occupy space; on no plausible construal of mereological composition does a mereological (...) sum of non-space-occupying entities occupy space; therefore, material objects are not mereological sums of properties.

The main concern of this essay is to make a case for the thesis that Leibniz conceived of his philosophy as a way of life in something like the sense articulated in the works of Pierre Hadot. On this view, philosophy was a type of conduct, or a mode of existing‐in‐the‐world, which had to be practised at each instant, with the goal of transforming the whole of the individual’s life. The essay also serves as an introduction to some of the (...) main themes in Hadot’s work. While it includes a brief discussion of a number of the central components of Leibniz’s philosophy conceived as a way of life, the essay does not aim to do so in great detail. Rather, it offers a manifesto and initial road map. (shrink)

Leibniz’s claim that it is possible for us to gain metaphysical knowledge through reflection on the self has intrigued many commentators, but it has also often been criticized as flawed or unintelligible. A similar fate has beset Leibniz’s arguments against materialism. In this paper, I explore one of Leibniz’s lesser-known arguments against materialism from his reply to Bayle’s new note L, and argue that it provides us with an instance of a Leibnizian “argument from reflection”. This argument, I further show, (...) does not constitute a flawed appeal to mere introspection, but is in fact securely grounded in an important corollary of the Principle of Sufficient Reason: Leibniz’s Principle of Intelligibility.
