A fairly long (~15,000 word) overview of ancient theories of freedom and determinism. It covers the supposed threat of causal determinism to "free will," i.e., the sort of control we need to have in order to be rightly held responsible for our actions. But it also discusses fatalistic arguments that proceed from the Principle of Bivalence, what responsibility we have for our own characters, and god and fate. Philosophers discussed include Aristotle, Epicurus, the Stoics, Carneades, Alexander of Aphrodisias, and Plotinus. (...) Plato is mentioned in passing a few times in connection with other philosophers. (shrink)

An overview of the ancient philosophers and their philosophical system (divided into the fields of logic, physics, and ethics) comprising the living, organic, enduring, and evolving body of interrelated ideas identifiable as the Stoic perspective.

Pierre Bayle shows that, in order to avoid devastating objections, materialism should postulate that the property of thinking does not emerge from certain material combinations but is present in matter from the start and everywhere—a hypothesis recently revived and labelled “panpsychism”. There are reasons for entertaining the idea that Bayle actually considers this enhanced materialism to be tenable, as it might use the same line of defence that Bayle outlined for Stratonism. However, this would lead to a view similar to (...) Locke’s superaddition theory, and I contend that such cannot be Bayle’s position because he embraces the Cartesian principle that each substance has only one principal attribute. This makes untenable, in his eyes, any system that conjoins thought with matter in the same simple substance. By contrast, this makes clear which kinds of metaphysics and epistemology panpsychists need to adopt to defend their view. (shrink)

The volume contains 11 contributions of the best experts on the topics of fate, fortune and free will, in reference to Ancient Philosophy: Plato, Aristotle, Stoicism, Epicureanism, Plotinus.

It is often assumed that Epicurean happiness can be achieved by everyone alike. This paper offers a corrective to this view. While it is true that the Epicureans abolish traditional differences among people like those between the sexes, social classes, and so on, they also maintain that there are people who are incapable of achieving happiness because they lack a certain bodily make-up or because they do not have the right ethnic or cultural origin.

In Epicurean cosmology, material reconstitution, or palingenesis (παλιγγενεσία) is the necessary consequence of the infinity of time and the eternity of atoms. I examine Lucretius’ treatment of this phenomenon (DRN 3.843–864) and consider the extent to which his view enables us to develop an Epicurean response to the question: what makes a person at two different times one and the same person? I offer a reading of this passage in the light of modern accounts of persistence and identity, and what (...) Lucretius states in Books 3 and 4 about memory and the soul’s motions. Guided by the metaphysical implications of this analysis, I determine the type of relation which, according to Lucretius, holds between the mental and the physical. (shrink)

This chapter explores the topic of self-knowledge in ancient thought, asking in particular what the ancient concept (or concepts) of knowing oneself amounts to. The chapter begins by contrasting the issues which occupy ancient and contemporary discussions of self-knowledge, and the obvious points of continuity and discontinuity between the two. The author isolates two forms of self-knowledge: cognitive self-knowledge or knowledge of one’s own mental states, and dispositional self-knowledge or knowledge of one’s moral or intellectual dispositions, and traces the treatment (...) of these forms of self-knowledge in the works of Plato, Aristotle, Hellenistic philosophers, and Plotinus. In the course of discussing the texts of each thinker or school, and the relevant scholarship, this chapter also canvasses the ways in which the chapters in the rest of this volume seek to engage with some of the problems or issues that have emerged.

This paper analyzes the ontology and epistemology of time in Lucretius’ De rerum natura. It uses the physiology of perception as well as epistemology to shed new light on the metaphysics. It presents an exegesis-based interpretation of the nature of time and of its perception, both arguing for and refining this interpretation by showing its explanatory power. The paper shows that Lucretius represents the perception of time or sensus temporis as a distinct sensory faculty, reconstructs how it emerges and operates, (...) and relates it to his account of perception more generally. The sense of time in turn is seen to explain aspects of related faculties, including thought and sight, and cases of apparent simultaneity. The paper thus contributes to, among other things, our understanding of the speed of perception and Lucretius’ account of the nature of time itself — arguing that Lucretius represents time as both continuous (not atomic) and real, as well as something perceived.

Sextus Empiricus ascribes to Epicurus a curious account of truth and falsehood, according to which these characteristics belong to things in the world about which one speaks, not to what one says about them. I propose an interpretation that takes this account seriously and explains the connection between truth and existence that the Epicureans also seem to recognise. I then examine a second Epicurean account of truth and falsehood and show how it is related to the first.

This paper considers three accounts of the relationship between personal immortality and materialism. In particular, the pagan mortalism of the Epicureans is compared with the Christian mortalism of Thomas Hobbes and John Locke. It is argued 1) that there are significant similarities between these views, 2) that Locke and Hobbes were, to some extent, influenced by the Epicureans, and 3) that the relation between mortality and materialism is not as straightforward as is commonly supposed.

In Human Nature, Hobbes argues for what I call the ‘Great Deception Thesis’: “whatsoever accidents or qualities our senses make us think there be in the world, they are not there, but are seemings and apparitions only.” I argue that both the thesis and Hobbes’ arguments for it have been misunderstood. Rather than arguing for indirect realism or a primary/secondary quality distinction, Hobbes claims that no sensory experience resembles its object. I conclude by showing how Hobbes can account for the (...) usefulness of images even in the absence of any resemblance between those images and the objects that cause them. If I am right, Hobbes presents a distinctive and intriguing theory of perception, one that emphasizes the dynamic nature of experience. (shrink)

This essay offers a reading of a difficult passage in the first book of Lucretius' "De Rerum Natura" in which the poet first explains the Epicurean account of time and then responds to a worry about the status of the past (1.459-82). It identifies two possible readings of the passage, one of which is compatible with the claim that the Epicureans were presentists about the past. Other evidence, particularly from Cicero "De Fato", suggests that the Epicureans maintained that all true (...) assertions must have a contemporaneous truth-maker and that no contingent future-tensed assertions are true. It appears, however, that they did not assert a symmetrical view of past-tensed assertions. There is no compelling reason, therefore, to think that the Epicureans were presentists about the past.

Democritus is generally understood to have anticipated the seventeenthcentury distinction between primary and secondary qualities. I argue that this is not the case, and that instead for Democritus all sensible qualities are conventional.

This paper is a commentary on Epicurus’ Kuria Doxa 33, according to which “justice is not anything in itself [τι καθ᾽ ἑαυτό].” It explores what it means for something to exist ‘in itself’ in Hellenistic philosophy, speculating on the sources of Epicurean technical vocabulary and suggesting an ontological reading of KD 33.

Diachronic emergence has recently been characterised as transformation. This aims to capture the thought that the entities that emerge are radically new or different. Transformation is hence closely linked with a central (but rarely raised) challenge for all emergentists: how to account for the identity and individuation of entities involved in emergence. With this challenge in view, I develop and probe four interpretations of transformation: addition, replacement, fusion, and transubstantiation. Of those, transubstantiation provides the most plausible response to the challenge (...) about identity. Accordingly, diachronic emergence is a transformative process whereby an individual passes from one primary kind to another. (shrink)
