Nature dictates what men shall seek and prompts them to seek it; a possibility of happiness is thus generated and only its fulfilment would justify nature and man in their common venture.

Context

“Eventual satisfactions, while their form and possibility must be determined by animal tendencies, alone render these tendencies vehicles of the good. The direction in which benefit shall lie must be determined by irrational impulse, but the attainment of benefit consists in crowning that impulse with its ideal achievement. Nature dictates what men shall seek and prompts them to seek it; a possibility of happiness is thus generated and only its fulfilment would justify nature and man in their common venture. It is the seat of value.
Satisfaction is the touchstone of value; without reference to it all talk about good and evil, progress or decay, is merely confused verbiage, pure sophistry in which the juggler adroitly withdraws attention from what works the wonder—namely, that human and moral colouring to which the terms he plays with owe whatever efficacy they have.” source
