How many senses there are, and the substance and activity of each.1965
1 · Hearing as the teacher of the mind
I.51.1 · Wachsmuth pp. 481
Simylus.
Five are the senses that a human being has:[touch, sight, hearing, taste, smell].Of all these one has the greatest authority,hearing: no one grew wise by eating,nor by ⟨touching, nor smelling⟩, nor by seeingwhat is beneficial . . . . . . . . . .But through hearing and learning good thingsmany have become wise; for this alonethe mind has kept as its own teacher:. . . . . . . . . . . . .as a judge, an arbiter, or a master.1966
2 · Five specific senses
I.51.2 · Wachsmuth pp. 481
⟨Aëtius.⟩
The Stoics hold that the specific senses are five: sight, hearing, smell, taste, touch.1967
3 · Common perception
I.51.3 · Wachsmuth pp. 482
Aristotle does not speak of a sixth sense, but of a common perception, ⟨the faculty⟩ that judges composite forms. To it all the simple senses contribute, each its own impressions; in it resides the capacity to pass from one thing to another, for example between shape and movement.1968
4 · More senses
I.51.4 · Wachsmuth pp. 482
⟨Aëtius.⟩
Democritus holds that there are more senses in nonrational animals, in the wise, and in the gods.1969
5.1 · The fivefold perceptive capacity
I.51.5.1 · Wachsmuth pp. 482
⟨Didymus.⟩
Aristotle. The perceptive capacity, which is the characteristic shared by all animals (for perception distinguishes an animal from a plant), appears to be fivefold. One part of it is sight, another hearing, another smell, another taste, another touch.1970
5.2 · Imagination, memory, and belief
I.51.5.2 · Wachsmuth pp. 482
There is also a certain composite perception, in which the whole capacity for forming images arises, together with ⟨the⟩ capacity for memory and the capacity for belief; the latter is therefore not without a share in intellect. We perceive when the perceptive faculty undergoes some affection.1971
6 · From perception to knowledge
I.51.6 · Wachsmuth pp. 482
Plato, from the Phaedo.
“The brain is what provides the perceptions of hearing, seeing, and smelling; from these memory and belief would arise, and from memory and belief, once they have attained stability, knowledge would arise in accordance with these.”1972
7 · Like perceived by like
I.51.7 · Wachsmuth pp. 483
Empedocles.
For with earth we have seen earth, with water water,with aether divine aether, and with fire destructive fire.1973
