Nature seems at each man's birth to have marked out the bounds of his virtues and vices, and to have determined how good or how wicked that man shall be capable of being.
No man deserves to be praised for his goodness, who has it not in his power to be wicked. Goodness without that power is generally nothing more than sloth, or an impotence of will.
Our actions seem to have their lucky and unlucky stars, to which a great part of that blame and that commendation is due which is given to the actions themselves.
