Myles Burnyeat maintains that Aristotelian epistêmê, in so far as it deals with explanations, is properly identified as understanding rather than as knowledge. Although Burnyeat is right in thinking that the cognitive achievement Aristotle typically has in mind is not justified true belief, Aristotelian epistêmê cannot be equated with understanding. On some occasions in Aristotle's writings (e.g. Apo 71a4), the term designates a particular science such as mathematics; on others (e.g. Apo 72b18-20), it designates the grasp of a first principle; (...) on others (e.g. Apo 94a20) it is a systematic grasp of fact and explanation that is properly termed understanding; and on still others (e.g. N. Ethics 1147a22) it is that combination of factual knowledge and competency in demonstration that qualifies as expertise or disciplinary mastery. (shrink)

This article addresses some crucial assumptions that are rarely acknowledged when organisms and machines are compared. We begin by presenting a short historical reconstruction of the concept of “machine.” We show that there has never been a unique and widely accepted definition of “machine” and that the extant definitions are based on specific technologies. Then we argue that, despite the concept's ambiguity, we can still defend a more robust, specific, and useful notion of machine analogy that accounts for successful strategies (...) in connecting specific devices (or mechanisms) with particular living phenomena. For that purpose, we distinguish between what we call “generic identity” and proper “machine analogy.” We suggest that “generic identity”—which, roughly stated, presumes that some sort of vague similarity might exist between organisms and machines—is a source of the confusion haunting many persistent disagreements and that, accordingly, it should be dismissed. Instead, we endorse a particular form of “machine analogy” where the relation between organic phenomena and mechanical devices is not generic but specific and grounded on the identification of shared “invariants.” We propose that the machine analogy is a kind of analogy as proportion and we elucidate how this is used or might be used in scientific practices. We finally argue that while organisms are not machines in a generic sense, they might share many robust “invariants,” which justify the scientists' use of machine analogies for grasping living phenomena.

In Nicomachean Ethics 1.6, Aristotle directs his criticism not only against the Platonic Idea of the Good but also against the notion of a universal Good. In this paper, I also examine some of the most interesting aspects of his criticism of the Platonic Good and the universal Good in Eudemian Ethics 1.8. In the EN, after using a series of disputable ontological arguments, Aristotle’s criticism culminates in a strong ethical or rather practical and, simultaneously, epistemological argument, from which a (...) dialectical postulatum emerges. This argument aims to show that we have to discover the dialectical stages or grades which constitute the relation between the ultimate End, i.e., the Good simpliciter or the absolute Good, and the relational goods till the last prakton good in which each specific praxis ends. According to the present reading, Aristotle sets out to establish a kind of Dialectic of the ends or Dialectic of the goods, which puts emphasis on the descent to the specific good, which is appropriate to and cognate with each individual, be that a person, praxis, science or craft. It is also suggested that this might be relevant to Aristotle’s tendency to establish a separation of phronēsis, i.e., practical wisdom, from sophia, i.e., wisdom, in the Nicomachean Ethics.

This doctoral thesis addresses a group of conceptual instruments that are central to Aristotle's philosophy, namely, the concepts of pros hen, homonymy, synonymy and multivocity. These instruments are crucial to many of Aristotle's works as he devotes himself to analysing the key notions in each of his investigations using these instruments. Despite the undisputable importance of these instruments, they display severe interpretative problems, which this thesis critically evaluates. The currently established view on the relationship between homonymy and multivocity is discussed (...) and then reassessed in order to approach the definition of the so-called pros hen structure. This approach takes into account a so-far undescribed distinction of types of examples Aristotle uses and sheds new light on the assessments of the role of the pros hen structure in Aristotle’s philosophy and the theories on development in Aristotle’s thought. Niels Tolkiehn studied Philosophy and Systematic Musicology at the University of Hamburg. He continued his studies as a doctoral student at the Munich School of Ancient Philosophy, a graduate school of the Ludwig-Maximilians-Universität München. Supervised by Prof. Dr. Christof Rapp, he was awarded his doctoral degree in 2019 with this dissertation. (shrink)
