We are members of one great body. Nature planted in us a mutual love, and fitted us for a social life. We must consider that we were born for the good of the whole.
Seneca the YoungerIt is man's duty to live in conformity with the divine will, and this means, firstly, bringing his life into line with 'nature's laws', and secondly, resigning himself completely and uncomplainingly to whatever fate may send him. Only by living thus, and not setting too high a value on things which can at any moment be taken away from him, can he discover that true, unshakeable peace and contentment to which ambition, luxury and above all avarice are among the greatest obstacles.
Seneca the Younger
