What is the first principle of Mencius?

Moral life begins from an inner capacity that can be preserved, extended, and practiced. Self-cultivation, education, and government should protect and enlarge that beginning.

Why does the unbearable heart matter?

It connects Mencius's account of human nature with his political thought. The spontaneous alarm one feels at another person's danger shows that humaneness has a real beginning.
