The research that I have carried out on the sense of hearing in the Aristotelian ambit is based on a personal interest in the medical aspects that can be found in the treaties of the Stagirite. If, on the one hand, there has always been very deep attention by the scholars to the phenomenon of perception, and still there is, on the other hand, although not ignored, hearing remains perhaps somewhat neglected or, however, not sufficiently investigated so far, despite its (...) importance; but, above all, the effort to consider all its various implications together and the whole Corpus Aristotelicum has not been accomplished up to today. This is the intent that I have purposed and which I hope to have at least partially achieved. Of course, it was a constant need to refer also to the other senses and, in general, to Aristotle's theory of perception; I have, however, tried to point out every possible aspects, which could explain the peculiarities of hearing. Without claiming in any way to draw up a rank list of the senses, since each of them, according to the different points of view, seems more or less to aspire to a kind of primacy, I was able to demonstrate the extraordinary importance of hearing and, within certain limits, his preferability. After an introductory chapter on the position of hearing among the other senses, I have proposed a rather long one, in which I more specifically dealt with the anatomical, physiological and pathological aspects (and, finally, even some physical-mathematical considerations, that I think of great philosophical and scientific relevance); then, it has been given ample space (and could not be otherwise) to the complex issue of the relationship between hearing and language, which made it possible to highlight, thanks to the comparative approach of the Aristotelian investigations in the biological ambit, the differences between sound, voice and speech, and to show the key role of hearing in order to learning (also animal) and intellectual development (especially human). In a final articulated chapter I approached what I consider the further possible implications of hearing, always clinging to the Aristotelian treatment: in addition to the physical phenomena of echo, roar, resonance and the psychophysicist ones of acoustic illusions, I could not exempt myself from talking about music, also in "technical" terms (as my limited skills in the field have allowed me to), but especially because of its educational features examined in the paragraph Emotions, morality and education, where hearing is reported as undisputed protagonist in the ethical, aesthetic, rhetorical, political ambits; the chapter, and the dissertation itself, are closed by some remarks about the relations of hearing with memory and recollection and with dream: apart from the latter, where sight seems to dominate, with the first two the auditory role is on the contrary of primary importance, despite still today people are often inclined to mention visual memory more frequently. Even from these few notes I think I can state that it was really worthwhile to dedicate a research to the sense of hearing, especially in regard to a Corpus so broad, rich, varied and complex, such as the Aristotelian one.

We have reason to think that a fundamental goal of natural science, on Aristotle’s view, is to discover the essence-specifying definitions of natural kinds—with biological species as perhaps the most obvious case. However, we have in the end precious little evidence regarding what an Aristotelian definition of the form of a natural kind would look like, and so Aristotle’s view remains especially obscure precisely where it seems to be most applicable. I argue that if we can get a better understanding (...) of how the forms of natural kinds are or come to be known, and how they make things intelligible, we can get a better appreciation of the nature of form in general, as well as solve certain puzzles about form and definition.

Aristotle is often named as the first zoologist or biologist because of his writings on animals. Although Aristotle’s major intention in these books was to illustrate his ideas of how knowledge and understanding might advance, at least one modern biologist (C. Darwin) has recognized Aristotle's depth and breadth as being of surviving merit. Of greater surprise is the ongoing attention that his works continue to receive, including publications in contemporary scientific journals. This review identifies 38 peer-reviewed papers on various topics (...) from Aristotle’s biological writings that have been published during the last 50 years. These papers are described according to content (genetics, population biology, anatomy, brain, movement), specific creatures (fish, scorpions, elephants, insects, birds), publication outlet, distribution over the fifty year period surveyed, and visible trends in the topics studied. It is concluded that, in the highly-competitive field of peer-reviewed scientific publication and citation, Aristotle's biology continues to excite the interest of scientists and remains salient to modern science itself.

The architects of the modern synthesis banned essentialism from evolutionary theory. This rejection of essentialism was motivated by Darwin’s theory of natural selection, and the continuity of evolutionary transformation. Contemporary evolutionary biology witnesses a renaissance of essentialism in three contexts: “origin essentialism” with respect to species and supraspecific taxa, the bar coding of species on the basis of discontinuities of DNA variation between populations, and the search for laws of evolutionary developmental biology. Such “new essentialism” in contemporary biology must be (...) of a new kind that accommodates relational (extrinsic) properties as historical essences and cluster concepts of natural kinds. (shrink)

Many biologists have accepted Ernst Mayr’s claim that evolutionary biology undermined an essentialist or typological view of species that had its roots in Platonic philosophy. However, Mayr has been accused of failing to support with textual evidence his attributions to Plato of these sorts of views about biology. Contemporary work in history and philosophy of biology often seems to take onboard Mayr’s account of Plato’s view of species. This paper seeks to provide a critical account of putative inconsistencies between an (...) evolutionary view of species and Platonic philosophy with renewed attention to the Platonic texts in light of recent Plato scholarship; I argue that claims that Plato held an essentialist view of species inconsistent with evolutionary biology are inadequately supported by textual evidence. If Mayr’s essentialist thesis fails, one might think that the intuition that Platonic philosophy is in tension with Darwinian evolution could nonetheless be accounted for by Plato’s apparent privileging of a certain sort of teleological explanation, a thesis that Mayr suggests in his 1959 paper on Louis Agassiz. However, this thesis also faces difficulties. Ernst Mayr’s Plato is more likely to be found in the writings of anti-evolutionary 19th century biologists like Mayr’s frequent target, Agassiz, than in a cautious reading of the Platonic dialogues themselves. Interlocutors in discussions of the history of biological thought and classificatory methods in biology should be cautious in ascribing views about biology to Plato and using terms like “Platonic essentialism.”.

Aristotle’s influence on D’Arcy Thompson was praised by Thompson himself and has been recognized by others in various respects, including the aesthetic and normative dimensions of biology, and the multicausal explanation of living forms. This article focuses on the relatedness of organic forms, one of the core problems addressed by both Aristotle’s History of Animals (HA), and the renowned chapter of Thompson’s On Growth and Form (G&F), “On the Theory of Transformations, or the Comparison of Related Forms.” We contend that, (...) far from being an incidental inspiration stemming from Thompson’s classicist background, his translation of HA played a pivotal role in developing his theory of transformations. Furthermore, we argue that Thompson’s interpretation of the Aristotelian method of comparison challenges the prevailing view of Aristotle as the founder of “typological essentialism,” and is a key episode in the revision of this narrative. Thompson understood that the method Aristotle used in HA to compare animal forms is better comprehended as a “method of transformations,” leading to a morphological arrangement of animal diversity, as opposed to a taxonomical classification. Finally, we examine how this approach to the relatedness of forms lay the foundation for a causal understanding of parts and their interconnections. Although Aristotle and Thompson emphasized distinct types of causes, we contend that they both differ in a fundamental sense from the one introduced by Darwin’s theory of natural selection, which was formulated as a solution to the species problem rather than the form problem. We conclude that Thompson’s interpretation of Aristotle’s approach to form comparison has not only impacted contemporary scholarship on Aristotle’s biology, but revitalized a perspective that has regained significance due to the resurgence of the problem of form in evo-devo.

The comparative method, closely identified with Darwinian evolutionary biology, also has a long pre-Darwinian history. The method derives its scientific power from its ability to interpret comparative observations with reference to a theory of relatedness among the entities being compared. Such scientifically powerful strong comparison is distinguished from weak comparison, which lacks such theoretical grounding. This paper examines the history of the strong comparison permitted by the comparative method from the early modern period to the threshold of the Darwinian revolution (...) in the mid nineteenth century. It interprets the work of early pioneers such as Belon, Willis, Perrault, and Tyson from this methodological perspective, rather than focusing on their particular anatomical findings. Although these early writers made formative scientific contributions through their comparative investigations, the more theoretically grounded application of the comparative method by Geoffroy, Cuvier, and Owen was instrumental in laying the foundation for its later incorporation into Darwinian evolutionary theory.

Sense experience, naïvely conceived, is a way of knowing perceptible properties: the colors, sounds, smells, flavors, and textures in our perceptual environment. So conceived, ordinary experience presents the perceiver with the essential nature of a property like Sky Blue or Middle C, such that how the property appears in experience is identical to how it essentially is. In antiquity, as today, it was controversial whether sense experience could meet the conditions for knowledge implicit in this naïve conception. Aristotle was a (...) partisan in this debate, but his position is poorly understood. This dissertation examines how Aristotle’s perceptual psychology responds to ancient challenges to the naïve conception, and so articulates his defense of perceptual knowledge. -/- Aristotle’s defense relies on an ontology of “perceptual qualities"—a core class of perceptible properties—according to which those qualities, despite having a perceiver-independent essence rooted in the physics of causation and affection, nevertheless can be present in experience as they essentially are. Chapter 1 defends this realist and objectivist reading against competing interpretations, which overlook a crucial distinction between perceptual qualities and perceptual objects. Chapter 2 presents Aristotle’s ontology as a physicalism that uncharacteristically allows for perceptual qualities to appear in experience as they essentially are. -/- This ontology informs Aristotle’s account of the psychological conditions under which perceivers actually are presented with the essence of perceptual qualities. The locus of this account is an obscure passage where Aristotle purports to show that the senses “discriminate” perceptual qualities because the senses are “mean states” (An. 2.11, 424a5–7). Chapter 3 develops a comprehensive interpretation of the sensory mean state, which Chapter 4 uses to elucidate Aristotle’s argument for sensory discrimination. Sensory discrimination turns out to be a process in which the essence of a perceptual quality comes to be present in the affection it produces in a perceiver. For Aristotle, this shows that sense perception meets a condition for knowledge that his predecessors, including Plato, thought it could not meet. For in his view, but not in theirs, sense experience shares in both the truth and the essence of the qualities it perceives. (shrink)

Species are central to biology, but there is currently no agreement on what the adequate species concept should be, and many have adopted a pluralist stance: different species concepts will be required for different purposes. This thesis is a multidimensional analysis of species pluralism. First I explicate how pluralism differs monism and relativism. I then consider the history of species pluralism. I argue that we must re-frame the species problem, and that re-evaluating Aristotle's role in the histories of systematics can (...) shed light on pluralism. Next I consider different forms of pluralism: evolutionary and extra-evolutionary species pluralism, which differ in their stance on evolutionary theory. I show that pluralism is more than a debate about the species category, but a debate about which concepts are legitimate and a claim about how they interact with one another. Following that, I consider what sort of ontology is required for different forms of species pluralism. I argue that pluralists who deny the unity of biology will require a further plurality of frameworks, while those that ground their pluralism in evolution need only one framework. Finally, I consider what pluralism means for biological practice. I argue that species concepts are tools, and reflect on how pluralism can illuminate the way systematists approach the discovery of new species of yeast. Pluralism can make sense of the way species concepts are used, and can be developed to aid researchers in thinking about how to use the right tools for the right jobs. (shrink)

In the area of interest of the present dissertation it has been tried to examine the meanings that the notion of autarkeia acquires in the philosophical thought of Aristotle, dealing initially with the problems concerning the ethical and political aspects of the term, that is the meaning that it acquires when it is referred to mankind, which on the other hand had already been examined by scholars, and then linger over the aspects of biology and Metaphysics. Just these latter, in (...) fact, until now had not been taken in consideration in a principal manner by scholars, and it is also because of this that it had explicitly been tried to conduct a research on autarkeia as most complete as possible, that is such to consider all of its recurrences in Aristotle.
