_ Source: _Volume 63, Issue 1, pp 64 - 86 Five times in the extant corpus, Aristotle refers to a distinction between two ways of being a ‘that for the sake of which’ that he sometimes marks by using genitive and dative pronouns. Commentators almost universally say that this is the distinction between an aim and beneficiary. I propose that Aristotle had a quite different distinction in mind, namely: that which holds between something and the aim or objective it is (...) in the business of producing or achieving, and that which holds between some instrument and the user of that instrument.

This chapter addresses an interpretive question about why Aristotle identifies generation, growth and nourishment as the three distinct functions or activities of nutritive soul. Scholars typically try to explain this by appealing to the shared goal of these activities, though there is no consensus about what that goal is: Does Aristotle think that generation is a way of keeping oneself alive (and thus that the shared goal is self-maintenance), or is nourishment really a quasi-generative activity (and thus that the shared (...) goal is “form (re)production”)? Rather than taking that approach, Gelber offers a different but complementary way of accounting for the unity of these activities, by focussing on the continuity of their shared physiological basis. As it is argued here, the fact that these biological processes form a continuous cycle stems from Aristotle’s adherence, in his biological theory, to principles from his hylomorphic metaphysics. Attending to the details in works such as Generation of Animals that focus on the mechanisms underlying generation, growth and nourishment, it is shown how we can construct a coherent account of the unity of the three nutritive soul activities.

How does Aristotle view the production of females? The prevailing view is that Aristotle thinks female births are teleological failures of a process aiming to produce males. However, as I argue, that is not a view Aristotle ever expresses, and it blatantly contradicts what he does explicitly say about female births: Aristotle believes that females are and come to be for the sake of something, namely, reproduction. I argue that an alternative to that prevailing view, according to which the embryo’s (...) sex is determined solely by “non-teleological necessity,” also misrepresents Aristotle’s view. As I show, the explanation Aristotle gives is more sophisticated and less egalitarian than the alternative account allows: There is some sense in which males are, for Aristotle, the “default” result. I offer instead an interpretation that can accommodate the asymmetry between Aristotle’s biological account of the production of males and females, but which does not imply that females are thereby teleological failures. There is no doubt that Aristotle thinks females are inferior to males in many respects. However, if he thinks that inferiority is grounded in biological facts, it is not the fact that females are the results of a failure of form to be realized. (shrink)

This argues for a reading of PA I.1, 639b11-640a9 as a continuous argument, which I divide into 3 main sections. Aristotle’s point in the first section is that teleological explanations should precede non-teleological explanations in the order of exposition. His reasoning is that the ends cited in teleological explanations are definitions, and definitions—which are not subject to further explanation—are appropriate starting points, insofar as they prevent explanations from going on ad infinitum. Moreover, I argue that Aristotle proceeds in the following (...) two sections to criticize certain non-teleological accounts offered by his predecessors on the grounds that they are explanatorily defective: I take Aristotle’s complaints to be that those accounts—unlike teleological explanations—neither begin from appropriate starting points nor entail the phenomena that they purport to explain. Along the way, I am defending an alternative way of understanding what "hypothetical necessity" refers to, for Aristotle. Comments are welcome! (shrink)

Despite his awareness that organisms are well suited to the habitats they are typically found in, Aristotle nowhere tries to explain this. It is unlikely that he thinks this “fit” (as I call it) between organisms and their habitats is simply a lucky coincidence, given how vehemently he rejects that as an explanation of the fit between organisms’ various body parts. But it is quite puzzling that Aristotle never explicitly addresses this, since it is a question that seemed so pressing (...) to later philosophers and biologists such as Darwin. In this paper I offer a solution to that puzzle. As I argue, the type of habitat an organism lives in is partly constitutive of its essence or nature. The reason Aristotle does not ask, for instance, why marsh-dweller birds live in marshes, is that it is simply constitutive of their nature that they do so. Given that habitat is built into a kind’s essence, the answer to such a question is obvious and the question would have seemed to him trivial. By attending to the details of his biological treatises, I show that Aristotle’s conception of a living being’s essence is much more nuanced than one can glean from his discussions in the Physics and Metaphysics alone.

This chapter is an examination of the way aporiai are employed in Aristotle’s scientific account of animal reproduction, and how they are resolved. I argue that – surprising as it may be, given what Aristotle says in Metaphysics B about the importance of going through aporiai – there seems to be nothing of much significance about his use of them, at least if we assume that genuine cases of aporiai are being tracked by use of aporia-language. I demonstrate this negative (...) thesis by systematically going through the examples. There seems to be no common purpose for which they are raised, they have no single type of structure, and they are not caused by any one sort of difficulty. (shrink)

Recently scholars have been claiming that Aristotle’s biological explanations treat “facts about matter”—facts such as the degree of heat or amount of fluidity in an organism’s material constitution—as explanatorily basic or “primitive.” That is, these facts about matter are taken to be unexplained, brute facts about organisms, rather than ones that are explained by the organism’s form or essence, as we would have expected from Aristotle’s general commitment to the causal and explanatory priority of form over matter. In this paper, (...) I present three considerations for rejecting the view that facts about matter are primitive. First, there is evidence that those putative unexplained facts about degrees of heat, dryness, fluidity, etc. are, in fact, explained. Second, there are certain cases, such as human intelligence, where it would be quite implausible to consider the explanation in terms of degrees of heat to be starting from what Aristotle considers primitive facts. Third, the idea that facts about matter are as explanatorily primitive as facts about form requires a particular conception of the causal processes that the explanations mirror. But this conception of the causal processes conflicts with the way Aristotle characterizes them in Generation of Animals. There, heat is not treated as a causal factor that works “independently” of soul. In my view, these three considerations provide compelling reason to reject the claim that Aristotle’s biology treats facts about matter as primitive. (shrink)

This paper explores the various ways Aristotle refers to and employs “heat and cold” in his embryology. In my view, scholars are too quick to assume that references to heat and cold are references to matter or an animal’s material nature. More commonly, I argue, Aristotle refers to heat and cold as the “tools” of soul. As I understand it, Aristotle is thinking of heat and cold in many contexts as auxiliary causes by which soul activities (primarily “concoction”) are carried (...) out. This, as I argue, is what it means to call them “tools” of soul. An upshot of this investigation is the fuller picture of Aristotle’s conception of efficient causation it provides in general, and the better understanding of the efficient causal operation of an organism’s nature or soul it provides in particular.

This article argues for an interpretation of Aristotle’s biological account of familial resemblance that allows us to read Aristotle’s embryology as employing the same concept of “form” as he employs in his Metaphysics. The dominant view for the last several decades has been that in order to account for the phenomenon of inherited characteristics, Aristotle’s biology must appeal to a “sub-specific” form, one that includes all of the traits that parents pass on to their offspring. That view, however, is not (...) only inconsistent with Aristotle’s essentialist metaphysics, but it also renders the embryological theory internally inconsistent. The interpretation I offer avoids both inconsistencies, and better coheres with what he actually says in Generation of Animals. (shrink)

Although ethics is an essential component of undergraduate medical education, research suggests current medical ethics curricula face considerable challenges in improving students’ ethical reasoning. This paper discusses these challenges and introduces a promising new mode of graduate and professional ethics instruction for overcoming them. We begin by describing common ethics curricula, focusing in particular on established problems with current approaches. Next, we describe a novel method of ethics education and assessment for medical students that we have devised, the Medical Ethics (...) Bowl. Finally, we suggest pedagogical advantages to MEBs when compared to other ethics curricula. (shrink)

My article began as a very short 250 words inspired by astrophysicist Jeff Hester's (pro-evolution) pages on entropy (Astronomy magazine - Oct. and Nov. 2017 - http://www.astronomy.com/magazine/jeff-hester/2017/09/entropys-rainbow and http://www.astronomy.com/magazine/jeff-hester/2017/10/entropy-redux). The letter I wrote pointed out evolution's pluses (eg adaptations) and minuses (regarding origins). It went on to speak of a human, scientific, entirely natural explanation for what is called God. It proposes that the true human condition after death and before birth is as a member of the (...) Elohim - a name used for God in the Old Testament which, according to World Book Encyclopedia, means the PLURAL MAJESTY OF THE ONE GOD. This led to a few hundred more words about why some people call an entirely natural process "supernatural". I speculate that it must be because of the applications in thousands of years of finding a successful theory of quantum gravity (union of quantum mechanics and Einstein's theory of gravity - general relativity). Like quantum mechanics and gravitation, those apps would include all space and all time, and would undoubtedly be as mysterious to us as our technology would initially be to the builders of Egypt's first pyramids. In years past, the denial of divine beings by science may have been logical. But times sometimes change radically. Such a paradigm shift seems to be upon us now, with the recent discovery of gravitational waves and the anticipation of quantum gravity. In changing times, scientists and philosophers and everyone must always keep open minds. Of course, proposing that the human condition after death and before birth is as a member of the Elohim means that humans of the far distant future must be capable of the creation attributed to God by many people throughout the centuries. Therefore, a subsection entitled "Creation Of The Infinite, Eternal Cosmos Using Electronic BITS, Pi And Imaginary Time" has been added to the end of this article. -/- . (shrink)
