Smell is formally analogous to taste, with kinds of odors paralleling kinds of flavors, but human taste is far more exact than human smell because taste is a kind of touch, and touch is the most exact human sense; this superior acuity in touch underlies humans’ superior wisdom and natural disposition for thought.
By Aristotle, from On the Soul
Key Arguments
- He states the structural analogy: 'It would seem, indeed, that while smell is analogous to taste, and similarly the kinds (eidos) of flavor to those of odor.'
- He asserts that human taste is 'more exact' specifically because it is a form of touch, and touch is the sense in which humans excel: 'human taste is more exact because it is a sort of touch, and this perceptual capacity is most exact in a human being.'
- He contrasts human touch with other senses, where humans are inferior to many animals: 'For in the others | 421 a 20 | he is inferior to many animals, but in touch he is much more exceedingly exact than the rest.'
- He infers a cognitive consequence: 'That is why he is also the wisest of the animals.'
- He offers an anthropological indication tying bodily softness (a tactile condition) to intellectual disposition: 'members of the human race (genos) are naturally well-disposed or naturally ill-disposed depending on this perceptual organ and on no other, since the hard-fleshed ones are naturally ill-disposed for thought, | 421 a 25 | whereas the soft-fleshed ones are naturally well-disposed.'

But some things have an odor and flavor that are analogous, I mean, for example, a sweet odor and a sweet taste, whereas others have ones that are contrary.

Context
II.9 (421a15–25), where Aristotle links the analogy between smell and taste to his broader thesis that touch is the most exact human sense and grounds humans’ intellectual superiority, using bodily softness vs. hardness as a sign of better or worse natural aptitude for thinking.
