animal, but he is a rational animal--an animal with the gift of reason.

Brute animals have not reason, but only instinct, i.e., they follow
certain impulses or feelings which God gave them at their creation. He
established certain laws for each class or kind of animals, and they,
without knowing it, follow these laws; and when we see them following
their laws, always in the same way, we say it is their nature. Animals
act at times as if they knew just why they were acting; but it is not
so. It is we who reason upon their actions, and see why they do them;
but they do not reason, they only follow their instinct.

If animals could reason, they ought to improve in their condition. Men
become more civilized day by day. They invent many things that were
unknown to their forefathers. One man can improve upon the works of
another, etc. But, we never see anything of this kind in the actions of
animals. The same kind of birds, for instance, build the same kind of
nests, generation after generation, without ever making change or
improvement in them. When man teaches an animal any action, it cannot
teach the same to its young. It is clear, therefore, that animals cannot
reason.

Though man has the gift of reason by which he can learn a great deal, he
cannot learn all through his reason; for there are many things that God
Himself must teach him. When God teaches, we call the truths He makes
known to us Revelation. How could man ever know about the Trinity
through his reason alone, when, after God has made known to him that It
exists, he cannot understand it? It is the same for all the other
mysteries.
