In this paper we first briefly review Bell's (1964, 1966) Theorem to see how it invalidates any deterministic "hidden variable" account of the apparent indeterminacy of quantum mechanics (QM). Then we show that quantum uncertainty, at the level of DNA mutations, can "percolate" up to have major populational effects. Interesting as this point may be it does not show any autonomous indeterminism of the evolutionary process. In the next two sections we investigate drift and natural selection as the locus of (...) autonomous biological indeterminacy. Here we conclude that the population-level indeterminacy of natural selection and drift are ultimately based on the assumption of a fundamental indeterminacy at the level of the lives and deaths of individual organisms. The following section examines this assumption and defends it from the determinists' attack. Then we show that, even if one rejects the assumption, there is still an important reason why one might think evolutionary theory (ET) is autonomously indeterministic. In the concluding section we contrast the arguments we have mounted against a deterministic hidden variable account of ET with the proof of the impossibility of such an account of QM. (shrink)

Sober (1992) has recently evaluated Brandon's (1982, 1990; see also 1985, 1988) use of Salmon's (1971) concept of screening-off in the philosophy of biology. He critiques three particular issues, each of which will be considered in this discussion.

This excellent book is a collection of Lennox's papers, published in the (...) last twenty years, on the structure and methodology of Aristotle's philosophy of biology. In spite of the fact that the papers have had little, if any, re-editing for inclusion in the present volume, the book presents a remarkably seamless and impressively argued interpretation not only of Aristotle's philosophy..

Self-Intellection and its Epistemological Origins in Ancient Greek Thought. Aldershot, England: Ashgate Publishing, 2002. Pp. x + 220. Cloth, $79.95. In this excellent re-working of his King's College Ph.D. thesis, Ian Crystal presents an account of the problem of self-intellection in Greek philosophy from Parmenides through Plotinus. The problem, at least as it (...) appears in ancient Greek philosophy, is connected to the way in which a faculty of soul relates to its proper object. For example, the proper object of the visual faculty is light, that of the auditory faculty sound, and it is the difference in kind between these proper objects that requires different faculties of soul in any account of how it is that we come to grasp the two different kinds of sensory data. Reason is itself a faculty of soul that is supposed to correspond to objects of cognition, but since it is possible to grasp, cognitively, the structure of this faculty the question arises: May this faculty function as its own object? The question is famously answered in the affirmative in Aristotle's treatise De anima at 430a2-5 on the grounds that any immaterial object of cognition is identical to thought itself (epi men gar tôn aneu hulês to auto esti to nooun kai to nooumenon).While this may seem like a peculiarly Aristotelian analysis of cognition (relying, as it does, on Aristotle's distinction between matter and form and his rather cryptic claim that the faculties of soul are actually what their proper objects are potentially), Crystal traces the idea both backwards and forwards in time, rooting the problem in Parmenides' general account of faculties of soul and tracing it through Plotinus's sophisticated account of noetic intellect, with visits along the way not only with Aristotle but Plato and the Stoics as well.The book is divided into three parts. In the first ("The Epistemological Origins") Crystal examines the evolution of the philosophical analysis of cognition from Parmenides through Plato. Parmenides, on this account, was the first to offer anything like a philosophical treatment of intellect (Greek nous). In particular, Parmenides distinguishes between a faculty of intellection and an object of that faculty. Plato, consciously working in the Parmenidean tradition, further analyses mind into its faculties and their proper objects but also gives a more detailed analysis of the epistemological subject. Specifically, Plato's treatment of the faculty in the Theaetetus provides an account of the structure of our cognitive faculty and how that structure relates to the metaphysics of the external world. It is here that Crystal recognizes the emergence of a linguistic component in the epistemic subject's cognitive activity (101; cf. Theaetetus189e6-190a6).Part II ("The Emergence of Self-Intellection") consists of a single chapter in which Crystal reads Aristotle's treatment of self-intellection in the De anima as "Aristotle's epistemological response to Plato." Since self-intellection per se really only emerges for the first time in the De anima, this chapter is in some sense the meatiest part of the book. We are given first a careful treatment of Aristotle's account of perception in DA3.2, affection in DA2.5 and De generatione et corruptione1.7, and the central problem of self-consciousness in DA3.2. The argument moves quickly here but Crystal's analysis is precise and clear. Next comes the analysis of the cognitive structure of intellect itself in DA3.4 and Crystal's account of how Aristotle's two aporiai (How can intellect be both a passive affection and something simple and impassive; and Is intellect itself an intelligible object) are responses to Plato's account of cognition at Theaetetus197c1-200d4 (the Aviary passage) on the one hand and to the general lack of an account of intelligible objects in the Theaetetus on the [End Page 489] other. On Crystal's account, Aristotle improves on Plato in the sense... (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:The Parmenides and Plato’s Late Philosophy by Robert G. TurnbullScott CarsonRobert G. Turnbull. The Parmenides and Plato’s Late Philosophy. Toronto: University of Toronto Press, 1998. Pp. xii + 209. Cloth, $50.00.Plato’s Parmenides presents a number of puzzles for the interpreter. Some of these are the result of the Neoplatonic interpretation of Plato’s late philosophy; due ultimately to Plotinus and still widely influential, it fails to give a satisfactory (...) account of such elements of Plato’s metaphysics as the mathematicals, forms as “universals,” and an “acquaintance” explanation of our awareness of sensibles and forms. Turnbull strikes a decisive blow against the Neoplatonic interpretation of the Parmenides. More importantly, he makes considerable progress, where others have achieved only limited success, in placing the Parmenides into the wider context of Plato’s later thought.The present work is primarily a translation of and commentary upon the Parmenides. The translation is not intended to be a literary work but rather as an aid to the reader of the commentary, and translation and commentary move forward together, section by section, as in Cornford’s edition. The translation is fairly literal, and some passages are omitted; in the notorious “exercise” of Part II the responses of Aristoteles are regularly elided wherever possible. In some places Turnbull has sacrificed English style in favor of interpretation-neutral renderings: “no many” for Zeno’s ou polla einai at 128b2, for example. While this can sometimes make the translation difficult to read in isolation, it is very useful for the knowledgeable but Greekless reader who can do without such interpretive intrusions as, for example, rendering to hen as “Unity” (Allen). The four final chapters serve to put the dialogue into its place in Plato’s later philosophy. An appendix discusses Cornford, Allen, Sayre, Miller, and Meinwald, as well as the standard lines of the Neoplatonic interpretation.The strength of Turnbull’s interpretation is its attention to literary as well as philosophical detail. The significance of the dramatic coherence among many passages from dialogues generally thought to be late, particularly the Timaeus, Theaetetus, Sophist, and Philebus, has attracted the attention of other commentators, but it has not always been so convincingly connected to the related philosophical issues. With the Theaetetus and Sophist the Parmenides has been called “critical” in the sense that some commentators see in these dialogues a reassessment on Plato’s part of the ontology of forms as described in the Meno, Phaedo, and Republic. Turnbull, by contrast, puts the Parmenides squarely in line with the Republic and Plato’s middle period generally by connecting the dramatic setting of the two dialogues through the characters of Glaucon and Adeimantus; this, in turn, connects with the Timaeus, which is set on the day following the discussion of the Republic. Similar dramatic ties relate the Theaetetus to the Sophist, and the presence of the Eleatic stranger in the latter and mention of Parmenides in the former complete the [End Page 355] artistic connections among these late dialogues and Plato’s middle period. The Philebus is connected with these dialogues because of its discussion of the four factors of the universe: Unlimited, Limit, the Mixture of Unlimited and Limit, and the Cause of the Mixture, factors that are also explored in Part II of the Parmenides.The philosophical connections among the dialogues have their foundation in Plato’s attempt to give an account of the rational structure of the world system (the World Animal of the Timaeus) that underscores the importance of the ultimate sources of intelligibility in the kosmos. The Parmenides opens with a discussion of Zeno’s largely destructive arguments against plurality; Plato then employs Zeno’s own “method of suppositions” to present a constructive thesis to the effect that “from the fundamental forms, through the generation of the intelligible numbers, thence to their being mixed with the Unlimited (apeiron), there is and can be nothing that is that fails to be a source of intelligibility or the intelligible product of such sources” (187). The difficult deductions of the second half of the Parmenides thus exhibit two aspects: a negative, or Parmenidean, version, and a positive, or Platonic version. The Parmenidean... (shrink)
