To the understanding of 'jen',Mencius is different from Confucius.'jen' in Mencius theories was degraded from relationship between man and nature.'jen' is a kind of mental constitution by which nature of man can be deduced.To nourish one's nature is the way to serve Heaven.Taking human nature as the reasoning starting point,Mencius asserted 'benevolent governance','heart governance'.Though Mencius claims a series of reform measures,it is utopia because his understanding to the relationship between man and nature is wrong,and his republic contrast is sharp within his reality.
