Simplicius’ project of harmonizing previous philosophers deserves to be taken seriously as both a philosophical and an interpretive project. Simplicius follows Aristotle himself in developing charitable interpretations of his predecessors: his distinctive project, in the Neoplatonic context, is the rehabilitation of the Presocratics (especially Parmenides, Anaxagoras and Empedocles) from a Platonic-Aristotelian perspective. Simplicius’ harmonizations involve hermeneutic techniques which are recognisably those of the serious historian of philosophy; and harmonization itself has a distinguished history as a constructive philosophical method.

ABSTRACT: In this paper I argue that the ‘discovery’ of the problem of causal determinism and freedom of decision in Greek philosophy is the result of a combination and mix-up of Aristotelian and Stoic thought in later antiquity; more precisely, a (mis-)interpretation of Aristotle’s philosophy of deliberate choice and action in the light of Stoic theory of determinism and moral responsibility. The (con-)fusion originates with the beginnings of Aristotle scholarship, at the latest in the early 2nd century AD. It undergoes (...) several developments, absorbing Epictetan, Middle-Platonist, and Peripatetic ideas; and it leads eventually to a concept of freedom of decision and an exposition of the ‘free-will problem’ in Alexander of Aphrodisias’ On Fate and in the Mantissa ascribed to him.

Themistius's (ca. 317–ca. 388 C.E.) paraphrase of the De Anima is an influential and important work; however, it is not now regarded as profound or original and thereby suffers from neglect. I argue that Themistius is misunderstood on the matter of Aristotle's productive and potential intellects. It is commonly held that Themistius gives to the productive intellect the role of illuminating images in order to produce universal thoughts in the potential intellect with epistemic certainty. I argue that Themistius's productive intellect (...) does not transform images to reveal the forms contained therein, but gives to the potential intellect the ability, first, to organize our sense-experiences in the course of acquiring rudimentary universal concepts and, then, to discover the forms of things by ordinary discursive thinking.

At "Categories" 12b5-16 Aristotle appears to regard the referents of declarative sentences, such as "Socrates is sitting," as what later writers were to call "complexe significabilia," i.e., items such as that Socrates is sitting. Simplicius' discussion of this passage in his commentary on the "Categories" clearly shows the influence of Stoic philosophy of language; but, if we follow the text printed by Kalbfleisch, Simplicius' commentary is seen to be a muddle of Stoic and Aristotelian elements, neither properly understood. It is (...) possible, however, by making a crucial emendation to the text, to preserve the Aristotelian integrity of Simplicius' theory of meaning. On that line Simplicius would be adopting the view that a declarative sentence refers to a thought in the first instance and a "complexe significabile" in the second instance. This view is plausibly the upshot of combining the "Categories" text with the first chapter of "De Interpretatione.". (shrink)

Intent upon harmonizing doctrines of their predecessors, some Neoplatonic commentators are faced with a problem of resolving doctrinal discrepancies so as to restore the συµφωνία in the history of philosophy. This article considers a particular example of this attempt ats harmonization: how Simplicius reconciles Aristotle's Categories with the Neopythagorean doctrine of the Pseudo-Archytas. The chronological inversion introduced by the counterfeiter produces remarkable effects on the late Platonic doctrine about general terms, to the extent that a commentator such as Simplicius works (...) to reduce the dissonance between Archytas' and Aristotle's words. This paper has three aims: to restore the general grid that Simplicius uses for reading and commenting on Archytas through Aristotle; to identify the exegetical strategies aimed at a doctrinal reconciliation; to consider a specific case, provided by the doctrine of weight, which engenders a new physical theory by Simplicius.

Historically embryogenesis has been among the most philosophically intriguing phenomena. In this paper I focus on one aspect of biological development that was particularly perplexing to the ancients: self-organisation. For many ancients, the fact that an organism determines the important features of its own development required a special model for understanding how this was possible. This was especially true for Aristotle, Alexander, and Simplicius, who all looked to contemporary technology to supply that model. However, they did not all agree on (...) what kind of device should be used. In this paper I explore the way these ancients made use of technology as a model for the developing embryo. I argue that their different choices of device reveal fundamental differences in the way each thinker understood the nature of biological development itself. In the final section of the paper I challenge the traditional view (dating back to Alexander's interpretation of Aristotle) that the use of automata in GA can simply be read off from their use in the de motu.

Aristotle in Physics I,1 says some strange-sounding things about how we come to know wholes and parts, universals and particulars. In explicating these, Simplicius distinguishes an initial rough cognition of a thing as a whole, an intermediate "cognition according to the definition and through the elements," and a final cognition of how the thing's many elements are united: only this last is επιστημη. Simplicius refers to the Theaetetus for the point about what is needed for επιστημη and the ways that (...) cognition according to the definition and through the elements falls short. By unpacking this reference I try to reconstruct Simplicius' reading of "Socrates' Dream," its place in the Theaetetus ' larger argument, and its harmony with other Platonic and Aristotelian texts. But this reconstruction depends on undoing some catastrophic emendations in Diels's text of Simplicius. Diels's emendations arise from his assumptions about definitions and elements, in Socrates' Dream and elsewhere, and rethinking the Simplicius passage may help us rethink those assumptions. (shrink)

This book provides a collection of sources, many of them fragmentary and previously scattered and hard to access, for the development of Peripatetic philosophy in the later Hellenistic period and the early Roman Empire. It also supplies the background against which the first commentator on Aristotle from whom extensive material survives, Alexander of Aphrodisias (fl. c. AD 200), developed his interpretations which continue to be influential even today. Many of the passages are here translated into English for the first time, (...) including the whole of the summary of Peripatetic ethics attributed to 'Arius Didymus'. (shrink)

Two texts that raise problems for Alexander of Aphrodisias' theory of universals are examined. "De anima" 90.2-8 appears to suggest that universals are dependent on thought for their existence; this raises questions about the status both of universals and of forms. It is suggested that the passage is best interpreted as indicating that universals are dependent on thought only for their being recognised as universals. The last sentence of "Quaestio" 1.11 seems to assert that if the universal did not exist (...) no individual would exist, thereby contradicting Alexander's position elsewhere. This seems to be a slip resulting from the fact that species with only one member are the exception rather than the rule. (shrink)
