Note: He was convinced that human nature could be determined solely by means of what human individuals tend to do without mentioning any other defining moment of their humanness. In this respect Bentham sides with Hobbes who has reduced human ends to desires. It is interesting to note that Hobbes has started his account of morality in the same personified manner as Bentham, as if some "Nature hath made" us the way we are, except that he pointed to the different masters of human conduct (aggressiveness and fear). Helvetius taught before Bentham that "physical pain and pleasure are the unrecognized principles of all human actions".
