in the state of nature, wrong doing is impossible; or if anyone does wrong, it is to himself, not to another. For no one by law of nature is bound to please another, unless he chooses, nor to hold anything to be good or evil, but what he himself, according to his own temperament, pronounces to be so; and to speak generally, nothing is forbidden by the law of nature, except what is beyond everyone’s power.
[..]men are chiefly guided by appetite, without reason; yet for all this they do not disturb the course of nature, but follow it of necessity. And therefore a man ignorant and weak of mind, is no more bound by natural law to order his life wisely, than a sick man is bound to be sound of body.
Spinoza in his posthumous work, the political treatise
