delight we take in our senses; for even apart from their usefulness

they are loved for themselves; and above all others the sense of

sight. For not only with a view to action, but even when we are not

going to do anything, we prefer seeing (one might say) to everything

else. The reason is that this, most of all the senses, makes us know

and brings to light many differences between things.

By nature animals are born with the faculty of sensation, and from

sensation memory is produced in some of them, though not in others.

And therefore the former are more intelligent and apt at learning than

those which cannot remember; those which are incapable of hearing

sounds are intelligent though they cannot be taught, e.g. the bee, and

any other race of animals that may be like it; and those which besides

memory have this sense of hearing can be taught.
