Mirth is like a flash of lightning, that breaks through a gloom of clouds, and glitters for a moment; cheerfulness keeps up a kind of daylight in the mind, and fills it with a steady and perpetual serenity.
Joseph AddisonOne would wonder to hear skeptical men disputing for the reason of animals, and telling us it is only our pride and prejudices that will not allow them the use of that faculty. Reason shows itself in all occurrences of life; whereas the brute makes no discovery of such a talent, but in what immediately regards his own preservation, or the continuance of his species. Animals in their generation are wiser than the sons of men; but their wisdom is confined to a few particulars, and lies in a very narrow compass. Take a brute out of his instinct, and you find him wholly deprived of understanding.
Joseph Addison
