How a law in itself can be the direct motive of the will (which is the essence of morality) is an insoluble problem for the human reason.

A Reaction

If that is the great man's final word, then it is tempting to switch to an empirical moral theory, such as that of Hobbes or Hume or E.O. Wilson, which starts from what motivations are available, and builds morality up from that.
