Philosopher: Both the consequences and the motives of human actions have bearing on the moral worth of those actions. Nonetheless, to be a moral agent one must have free will, because one cannot be a moral agent without desiring to conform to a principle. The philosopher's argument requires the assumption that ['nobody who acts without taking the consequences of the action into consideration is free', 'desiring to conform to a principle requires free will', 'it is impossible to have desires without also being a moral agent', 'one cannot be a moral agent if one lacks a concern for the consequences of actions']
