Here, for example, Thomas deals with the question of whether the animals have superior bodies to man because they come equipped with clothing (fur, feathers, thick hides) and weapons (teeth, horns, claws) whereas man is born defenseless and naked. Man, according to the Holy Catholic Faith, is the supreme material creation, so why are we so disadvantaged when compared with the animals we share the Earth with? Thomas gives a simple answer saying,
Horns and claws, which are the weapons of some animals, and toughness of hide and quantity of hair or feathers, which are the clothing of animals, are signs of an abundance of the earthly element; which does not agree with the equability and softness of the human temperament. Therefore such things do not suit the nature of man. Instead of these, he has reason and hands whereby he can make himself arms and clothes, and other necessaries of life, of infinite variety. Wherefore the hand is called by Aristotle (De Anima iii, 8), "the organ of organs." Moreover this was more becoming to the rational nature, which is capable of conceiving an infinite number of things, so as to make for itself an infinite number of instruments. (S. Th. Prima Pars, Q 91, Art. 3, Reply to Objection 2)That last sentence is particularly telling, in my view. Man wasn't given "clothing," in the form of homegrown feathers or fur, or "weapons," in the form of fearsome claws or teeth, not to be disadvantaged by God, but because he was given something so much greater - the ability to craft "an infinite number of things" to use as clothes and weapons. The lion seem better equipped than man, if the two are found together naked and alone, but give the man time and he can create power long range rifles that could drive lions to extinction (though, of course, we hope such will never happen). Again, an animal's natural coat may seem better protection than man's naked skin, until one realizes man can take the animals fur and make a coat of his own, for protection in the cold, or, in hot climes, decline to wear a coat at all. It is no accident man (and man alone) can survive on every continent, under the sea, and in outer space.
Such gems are to be found in Summa, which is well worth the time to read his answer to a "question" here or there.
