„The distinction, between what is done by labour, and what is done by nature, is not always observed.“
— James Mill Scottish historian, economist, political theorist and philosopher 1773 - 1836
'Labour produces its effects only by conspiring with the laws of nature.'
It is found that the agency of man can be traced to very simple elements. He does nothing but produce motion. He can move things towards one another, and he can separate them from one another. The properties of matter perform the rest.
