Ability To Do Otherwise

Both Descartes and Leibniz are on record as maintaining that acting freely requires that the agent ‘could have done otherwise.’ However, it is not clear how they could maintain this, given their other metaphysical commitments. In Leibniz's case, the arguments connected with this are well-rehearsed: it is argued, for example, that Leibnizian doctrines such as the Principle of Sufficient Reason and the thesis that God must will the best possible world preclude that the human could ever do other than she did. The question of whether Descartes can maintain that the agent is able to do otherwise in the face of his wider metaphysical commitments has received comparatively little attention. However, Chappell has recently noted that Descartes's thesis that God is the ‘total cause’ of everything seems to preclude the possibility of human freedom (where this includes the ability to do otherwise).

Principle Of Sufficient Reason

I examine Leibniz’s version of the Principle of Sufficient Reason with respect to free will, paying particular attention to Peter van Inwagen’s argument that this principle leads to determinism. Ultimately I conclude that Leibniz’s formulation is incompatible with free will. I then discuss a reformulation of the Principle of Sufficient Reason endorsed by Alexander Pruss that, I argue, manages to both retain the strength of Leibniz’s formulation and remain consistent with free will.

Quantum Phenomena

There is an argument for the existence of God from the incompleteness of nature that is vaguely present in Plantinga’s recent work. This argument, which rests on the metaphysical implications of quantum physics and the philosophical deficiency of necessitarian conceptions of physical law, deserves to be given a clear formulation. The goal is to demonstrate, via a suitably articulated principle of sufficient reason, that divine action in an occasionalist mode is needed (and hence God’s existence is required) to bring causal closure to nature and render it ontologically functional. The best explanation for quantum phenomena and the most adequate understanding of general providence turns out to rest on an ontic structural realism in physics that is grounded in the immaterialist metaphysics of theistic idealism.

Principle Of Sufficient Reason

Unlike brute ‘entities’, if conscious states (c-states) are brute, it will be a consequence of their primitive—viz., not admitting further elaboration—connection to their material base, what is commonly known as emergence. One might suppose the chief challenge to emergence comes from various materialist counter-proposals. However, given the distinctive character of c-states, a class of critics describe even materialist reductions as objectionable forms of emergentism. Instead, their fallback position is a reinvigorated panpsychism: consciousness is the intrinsic nature of the most fundamental particles. In this chapter the author examines that form of panpsychism, tracing its roots to a version of the Principle of Sufficient Reason and to suggestions aired in Bertrand Russell’s struggles with the issue. He concludes that this panpsychism fails, leaving the field to materialism and emergentist dualism.

In Being and Reason, Martin Lin offers a new interpretation of Spinoza’s core metaphysical doctrines with attention to how and why, in Spinoza, metaphysical notions are entangled with cognitive, logical, and epistemic ones. For example, according to Spinoza, a substance is that which can be conceived through itself, and a mode is that which is conceived through another. Thus, metaphysical notions, substance and mode, appear to be defined through a notion that is either cognitive or logical, being conceived through. What are we to make of the intimate connections that Spinoza sees between metaphysical, cognitive, logical, and epistemic notions? Or between being and reason? Lin argues against idealist readings according to which the metaphysical is reducible to or grounded in something epistemic, logical, or psychological. He maintains that Spinoza sees the order of being and the order of reason as two independent structures that mirror one another. In the course of making this argument, he develops new interpretations of Spinoza’s notions of attribute and mode, and of Spinoza’s claim that all things strive for self-preservation. Lin also argues against prominent idealist readings of Spinoza according to which the Principle of Sufficient Reason is absolutely unrestricted for Spinoza and is the key to his system. He contends, rather, that Spinoza’s metaphysical rationalism is a diverse phenomenon and that the Principle of Sufficient Reason is limited to claims about existence and nonexistence which are applied only once by Spinoza to the case of the necessary existence of God.

Mechanical Phenomena

The Principle of Sufficient Reason (PSR) says that, necessarily, every contingently true proposition has an explanation. The PSR is the most controversial premise in the cosmological argument for the existence of God. It is likely that one reason why a number of philosophers reject the PSR is that they think there are conceptual counter-examples to it. For instance, they may think, with Peter van Inwagen, that the conjunction of all contingent propositions cannot have an explanation, or they may believe that quantum mechanical phenomena cannot be explained. It may, however, be that these philosophers would be open to accepting a restricted version of the PSR as long as it was not ad hoc. I present a natural restricted version of the PSR that avoids all conceptual counter-examples, and yet that is strong enough to ground a cosmological argument. The restricted PSR says that all explainable true propositions have explanations.

Limited Scope

This chapter explores the meaning of Spinoza’s Principle of Sufficient Reason (the PSR) and the role it plays in his system. Some commentators have argued that Spinoza’s PSR applies to every truth and that Spinoza relies on it in deriving a great deal of his system. Against such interpretations, this chapter argues that Spinoza’s PSR is restricted to existential truths and is applied only once by Spinoza, to the case of the existence of God. In making this case, it considers Spinoza’s arguments for necessitarianism, causal and conceptual dependence, and the identity of indiscernibles, and it concludes that none of them rely on the PSR. It further argues that the limited scope of Spinoza’s PSR is a philosophical advantage because a fully unrestricted PSR is an unattractive doctrine that creates demands for explanation that cannot be met.

The Status

Abstract This paper discusses the concept of nothing (nothingness) from the point of logic and ontology (metaphysics). It is argued that the category of nothing as a denial of being is subjected to various interpretations. In particular, this thesis concerns the concept of negation as used in metaphysics. Since the Leibniz question ‘Why is there something rather than nothing?’ and the principle of sufficient reason is frequently connected with the status of nothing, their analysis is important for the problem in question. Appendix contains a short critical analysis of Heidegger’s famous statement Das Nichts nichtet.
