Aristotle: Theoretical Science

In this second of a 2-part survey of Aristotle’s epistemology, I present an overview of Aristotle’s views on technē (craft or excellent productive reason) and phronēsis (practical wisdom or excellent practical reason). For Aristotle, attaining the truth in practical matters involves actually doing the right action. While technē and phronēsis are rational excellences, for Aristotle they are not as excellent or true as epistēmē or nous because the kinds of truth that they grasp are imperfect and because they are excellent (...) states for humans, not simply speaking. I then discuss why Aristotle takes sophia (wisdom), understanding and scientific knowledge of the best things, to be its own excellence. While this is the best cognitive state for human beings, I argue that Aristotle thinks divine cognitive activity is different in kind and more perfect than any human activity. (shrink)

Aristotle's cognitive ideal is a form of understanding that requires a sophisticated grasp of scientific first principles. At the end of the Analytics, Aristotle tells us that we learn these principles by induction. But on the whole, commentators have found this an implausible claim: induction seems far too basic a process to yield the sort of knowledge Aristotle's account requires. In this paper I argue that this criticism is misguided. I defend a broader reading of Aristotelian induction, on which there's (...) good sense to be made of the claim that we come to grasp first principles inductively, and show that this reading is a natural one given Aristotle's broader views on scientific learning.

This chapter discusses the first part of Aristotle's Posterior Analytics A-33, 88b30-89a10. I claim that Aristotle is not concerned with an epistemological distinction between knowledge and belief in general. He is rather making a contrast between scientific knowledge (which is equivalent to explanation by the primarily appropriate cause) and some explanatory beliefs that falls short of capturing the primarily appropriate cause.

Aristotle, in his Metaphysics, not only tries to establish a relationship that is direct, coherent, inter-operational and "precise" between this science, its name as a science, and its object of study, but also begins an indignation that tries to set a science — materially adequate and formally correct — to study τὸ ὂν ᾗ ὂν. In order to complete this task, Aristotle does an in-focus strategy that consists on the diffusion of τὸ ὄν in its categories, that allows Aristotle the (...) possibility of formulate a science ἐπιστήμη to study τὸ ὂν ᾗ ὂν at the same time that supports the diffusion of τὸ ὄν in the "different categories or supreme genres" of τὸ ὄν. Due to this argumentation, Aristotle distinguishes the ἐπιστήμη σοφία of any other type of knowledge: the former is fundamentally an enquiry "about the first causes (πρῶτα αἴτια) and the principles (ἀρχὰς)". With this conception in mind, Aristotle was able to characterize several related forms of the ἐπιστήμη σοφία which, as a whole, eventually allow him to establish a science of the principles and causes "maximally universal and referred to…everything real", and in consequence, to "that that is, as long as something is". In this work, I will try to reconstruct such arguments, and offer some observations and conjectures referred to these notions that plausibly incline the scale in favor of an ontological reading of Aristotle’s Metaphysics, in order to contribute to clarify the confusion that exists between the aim of the discipline with the justification to establish the existence of its own object.

The article evaluates the Domain Postulate of the Classical Model of Science and the related Aristotelian prohibition rule on kind-crossing as interpretative tools in the history of the development of mathematics into a general science of quantities. Special reference is made to Proclus’ commentary to Euclid’s first book of Elements , to the sixteenth century translations of Euclid’s work into Latin and to the works of Stevin, Wallis, Viète and Descartes. The prohibition rule on kind-crossing formulated by Aristotle in Posterior (...) analytics is used to distinguish between conceptions that share the same name but are substantively different: for example the search for a broader genus including all mathematical objects; the search for a common character of different species of mathematical objects; and the effort to treat magnitudes as numbers.

Two central accounts of human cognition emerge over the course of the Middle Ages: the theory of divine illumination and an Aristotelian theory centered on abstraction from sense data. Typically, these two accounts are seen as competing views of the origins of human knowledge; theories of divine illumination focus on God’s direct intervention in our epistemic lives, whereas Aristotelian theories generally claim that our knowledge derives primarily (or even entirely) from sense perception. In this paper, I address an early attempt (...) to reconcile these two accounts—namely, Robert Grosseteste’s commentary on Aristotle’s Posterior Analytics—and I argue that Grosseteste’s efforts to bring Aristotle’s account of human cognition into harmony with a theory of divine illumination proves both philosophically interesting and largely successful. Grosseteste’s claim that God does not directly illumine our intellects in this life opens his theory to the worry that Grosseteste leaves the divine out of his theory of divine illumination in the CPA. Steven Marrone, for example, holds that Grosseteste’s Aristotelian focus in this work causes him to abandon the theory of divine illumination he advocated in the earlier De veritate in favor of a modified theory of “human” illumination. I argue in contrast that Grosseteste does give God a role in human knowledge in the CPA—a role that allows human beings to remain largely responsible for the acquisition of knowledge while still requiring God’s illumination for actual cognition. In short, I conclude that, although human bodies interfere with God’s direct illumination of our intellects, God nevertheless plays a crucial ideogenic role in human cognition by illuminating the objects of our intellection and making them intelligible to us.

According to the standard and largely traditional interpretation, Aristotle’s conception of nous, at least as it occurs in the Posterior Analytics, is geared against a certain set of skeptical worries about the possibility of scientific knowledge, and ultimately of the knowledge of Aristotelian first principles. On this view, Aristotle introduces nous as an intuitive faculty that grasps the first principles once and for all as true in such a way that it does not leave any room for the skeptic to (...) press his skeptical point any further. Thus the tradi- tional interpretation views Aristotelian nous as having an internalist justificatory role in Aristotelian epistemology. In contrast, a minority (empiricist) view that has emerged recently holds the same internalist justificatory view of nous but rejects its internally certifiable infallibility by stressing the connection between nous and Aristotelian induction. I argue that both approaches are flawed in that Aristotle’s project in the Posterior Analytics is not to answer the skeptic on internalist justificatory grounds, but rather lay out a largely externalist explication of scientific knowledge, i.e. what scientific knowledge consists in, without worrying as to whether we can ever show the skeptic to his satisfaction that we do ever possess knowledge so defined.

Self-identification strategy is presented so that a being identify itself wherein a subject is not an outer observer. A being is able to observe as a subject and be observed as an object. Thus, self-identification could be realized because a being acts to observe and be observed. A being is supposed to consist of spatio and temporal identities. They are considered to provide a basis of respective a spatio object to be observed and a temporal subject to observe. Two thought (...) experiments are presented for self-identification. In the first place, self-identification is explained by using the Out-of-Boddy experiences in no time flows. Secondly, a dream in a dream is provided to reveal a self-identification strategy in time flows. For this, dream is described by bi-directional movements in time flows. A teleological philosophy from the Aristotelian paradigm insists that the future decides the past which is thought to be the source of potentiality. Accordingly, the Aristotelian paradigm is modified to include the concept of a dream between the future and the past so that the reason why versatile a priori being such as Schrödinger's cat is created is explained and how they are distinguished among ontological potentiality by a teleological causation.
