One of the animals which a generous and sociable man would soonest become is a dog. A dog can have a friend; he has affections and character; he can enjoy equally the field and the fireside; he dreams, he caresses, he propitiates; he offends and is pardoned; he stands by you in adversity; he is a good fellow.

Man is a noble animal, splendid in ashes and pompous in the grave.

Man is the only animal for whom his own existence is a problem which he has to solve and from which he cannot escape.
