In Metaphysics Γ, Aristotle argues against those who seem to accept contradictions. He distinguishes between the Sophists, who deny the principle of non-contradiction through arguments, and the Natural Philosophers, whose physical investigations lead to the acceptance of objective contradictions. Heraclitus’ name appears throughout the discussion. Usually, he is associated with the discussion against the Sophists. In this paper, I explore how the discussion with the Natural Philosophers may illuminate both the interpretation of Heraclitus by Aristotle and Heraclitus’ own worldview. To (...) refute the Natural Philosophers, Aristotle proposes a general reconstruction of their reasoning. Roughly, relying on sensory evidence (A1), they see that the same thing changes from one opposite to another (A2). Such a change appears to characterize a generation out of non-being, which a Natural Philosopher does not accept (A3). To solve the problem, despite their different worldviews, Natural Philosophers hint at a state in which opposites co-occur, characterizing an objective contradiction (C). Looking at the discussion in Metaphysics Γ and Heraclitus fragments, sections 1–3 show how assumptions A1, A2, and A3 easily apply to Heraclitus. The case of the conclusion is more challenging. In the case of the Pluralists, the co-existence of opposites characterizes a state in which there is no generation. Such a view does not fit Heraclitus’ mobilism. To argue that Aristotle’s argument is general enough to encompass dynamic views, I examine his problematization of accepting the change of change in Metaphysics K and Physics V. There, after re-stating several points that appear in Metaphysics Γ, Aristotle argues that accepting the becoming of another becoming leads to a state of contradiction in which the becoming is perishing. Heraclitus’ B8, cited in Nicomachean Ethics, gives evidence that, for Aristotle, Heraclitus puts a process at the origin of an opposite process. Moreover, after examining the expression ‘living the death/dying the life’ in B62, I argue that Heraclitus was aware that his worldview implied a dynamic objective contradiction. Finally, an analysis of elemental changes in B36 proves that accepting objective contradictions does not make Heraclitus’ worldview less attractive. (shrink)

This article considers an interpretative model for the study of Heraclitus, which was first put forward by Alexander Mourelatos in 1973, and draws upon a related model put forward by Julius Moravcsik beginning in 1983. I further develop this combined model and provide a motivation for an interpretation of Heraclitus. This is also of interest for modern metaphysics due to the recurrence of structurally similar problems, including the ‘colour exclusion’ problem that was faced by Wittgenstein. Further, I employ the model (...) to shed new light on Heraclitus’ image of the river, while relating potential readings to various contemporary metaphysical views. (shrink)

In my paper, I shall provide a reading of Diogenes of Apollonia such that his understanding of the metaphysics of differentiation and of individual ensoulment may constitute an ingenious answer to the problems of his time. To this extent, I will argue that Diogenes' worldview solves the difficulties of Anaxagoras' metaphysics and successfully integrates mentality in a causally closed conception of nature. Finally, I will suggest that a Diogenes-inspired approach might be relevant to treat some pressing concerns in the contemporary (...) philosophy of mind – thus demonstrating how his production might offer some interesting solutions for the problems of our time too.

Are there any metaphysically basic (i.e., absolutely fundamental) entities in the cosmos on which all the other entities in the cosmos depend? If not, how are the various entities in the cosmos related to each other in terms of relative fundamentality? These questions have been of interest since the birth of philosophy. In this paper I argue that, for the early Greek philosopher, Heraclitus, there are no metaphysically basic entities. Rather, 1) the various entities in the cosmos are metaphysically interdependent (...) and 2) the cosmos itself and its parts are metaphysically interdependent. I call this view cosmic interdependence. I demonstrate its distinctiveness and argue for its contemporary significance with respect to the grounding structure of quantum entanglement. (shrink)

In the analysis of Anaxagoras’ physics in view of the relation between his teachings on multitude and heterogeneity, two central questions emerge: 1) How can the structure of the universe considered purely mereo-topologically help us explain that at the first cosmic stage no qualitative difference is manifest in spite of the fact that the entire qualitative heterogeneity is supposedly already present there? 2) How can heterogeneity become manifest at the second stage, resulting from the noûs intervention, if according to fragment (...) B 6 such a possibility requires the existence of “the smallest”, while according to the general principle stated in fragment B 3 there is not “the smallest” but always only “a smaller”? This paper showcases the perplexity of these two questions but deals only with the former. The answer follows from Anaxagoras’ being a thoroughgoing infinitist in the way in which no Greek physicist was: the principle of space isotropy operative in geometry is extended to physics as well. So any two parts of the original mixture are similar to each other not only in view of the smaller-larger relation but also because each contains everything that the other one contains. This in effect means that at the stage of maximal possible heterogeneity each part of any part contains infinitely many heterogeneous parts of any kind whatsoever. So, neither can there be homogeneous parts in view of any qualitative property, nor can there be predominance in quantity of parts of any kind that would make some property manifest. (shrink)
