The individual has a free-will choice about whether to integrate (put together so they will not fight each other) all his impulses and also his intellect, or to give up and just act on whatever impulse is being felt at the moment. So for Mencius the best path for a human being is to plan and to act to make himself or herself well balanced, integrated (not in a fight with himself or herself and wanting to do both one thing and its opposite), and so a useful person to society.
