Man perfected by society is the best of all animals; he is the most terrible of all when he lives without law and without justice. If he finds himself an individual who cannot live in society, or who pretends he has need of only his own resources do not consider him as a member of humanity; he is a savage beast or a god.
AristotleAll human actions have one or more of these seven causes: chance, nature, compulsions, habit, reason, passion, desire.
AristotleFor nature by the same cause, provided it remain in the same condition, always produces the same effect, so that either coming-to-be or passing-away will always result.
Aristotle
