Man is by nature a political animal.
--
Book I, 1253.a2Aristotle
Thus society is born, as something required by nature, and (because this nature is human nature) as something accomplished through a work of reason and will, and freely consented to. Man is a political animal, which means that the human person craves political life, communal life, not only with regard to the family community, but with regard to the civil community.
Jacques Maritain
The erotic instinct is something questionable, and will always be so whatever a future set of laws may have to say on the matter. It belongs, on the one hand, to the original animal nature of man, which will exist as long as man has an animal body. On the other hand, it is connected with the highest forms of the spirit. But it blooms only when the spirit and instinct are in true harmony. If one or the other aspect is missing, then an injury occurs, or at least there is a one-sided lack of balance which easily slips into the pathological. Too much of the animal disfigures the civilized human being, too much culture makes a sick animal.
Carl Jung
Evolution is not finished; reason is not the last word nor the reasoning animal the supreme figure of Nature. As man emerged out of the animal, so out of man the superman emerges.
Sri Aurobindo
Physical evils are in nature inseparable from animal life, they commenced existence with it, and are its concomitants through life; so that the same nature which gives being to the one, gives birth to the other also; the one is not before or after the other, but they are coexistent together, and contemporaries; and as they began existence in a necessary dependance on each other, so they terminate together in death and dissolution. This is the original order to which animal nature is subjected, as applied to every species of it. The beasts of the field, the fowls of the air, the fishes of the sea, with reptiles, and all manner of beings, which are possessed with animal life; nor is pain, sickness, or mortality any part of God's Punishment for sin. On the other hand sensual happiness is no part of the reward of virtue: to reward moral actions with a glass of wine or a shoulder of mutton, would be as inadequate, as to measure a triangle with sound, for virtue and vice pertain to the mind, and their merits or demerits have their just effects on the conscience, as has been before evinced: but animal gratifications are common to the human race indiscriminately, and also, to the beasts of the field: and physical evils as promiscuously and universally extend to the whole, so "That there is no knowing good or evil by all that is before us, for all is vanity." It was not among the number of possibles, that animal life should be exempted from mortality: omnipotence itself could not have made it capable of externalization and indissolubility; for the self same nature which constitutes animal life, subjects it to decay and dissolution; so that the one cannot be without the other, any more than there could be a compact number of mountains without valleys, or that I could exist and not exist at the same time, or that God should effect any other contradiction in nature...
Ethan Allen
When a man confines an animal in a cage, he assumes ownership of that animal. But an animal is an individual; it cannot be owned. When a man tries to own an individual, whether that individual be another man, an animal or even a tree, he suffers the psychic consequences of an unnatural act.
