One of the main ideas of Confucianism is filial piety and living in a patriarchal society. It replaces the caste system with 5 important societal relationships: friend-friend, wife-husband, subject-ruler, older brother-younger brother, and child-parent. Confucianism believed in self governance and a government that cares about its people. Legalism involves treating people harshly. One of the main themes of legalism is that human nature is bad, so people must be controlled. It involves destroying ideologies that differ from your own beliefs so everyone in a kingdom thinks the same way. If I was a ruler, I would most likely choose a legalistic government. I think legalism would help unite the empire in knowledge. Everyone would think the same way. I think Confucianism is a good philosophy, but it focuses more on human relationships than on government. If I leaded a legalistic civilization, I could order everyone to get an education so we could be considered an intelligent civilizaiton.
