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.
