And even if we reduce this to the true natural wants as to which our race is thoroughly agreed, or on the other hand, raise ever so high man’s skill to accomplish his imagined purposes; yet, even thus, what man understands by happiness, and what is in fact his proper, ultimate, natural purpose (not purpose of freedom), would never be attained by him. For it is not his nature to rest and be contented with the possession and enjoyment of anything whatever. On the other side, too, there is something wanting. Nature has not taken him for her special darling and favoured him with benefit above all animals. Rather, in her destructive operations, — plague, hunger, perils of waters, frost, assaults of other animals great and small, etc., — in these things has she spared him as little as any other animal.
