Whether the body of man was given an apt disposition?

Objections

Objection 1 : It would seem that the body of man was not given an apt disposition. For since man is the noblest of animals, his body ought to be the best disposed in what is proper to an animal, that is, in sense and movement. But some animals have sharper senses and quicker movement than man; thus dogs have a keener smell, and birds a swifter flight. Therefore man's body was not aptly disposed.
Objection 2 : Further, perfect is what lacks nothing. But the human body lacks more than the body of other animals, for these are provided with covering and natural arms of defense, in which man is lacking. Therefore the human body is very imperfectly disposed.
Objection 3 : Further, man is more distant from plants than he is from the brutes. But plants are erect in stature, while brutes are prone in stature. Therefore man should not be of erect stature.
