“Those who value wisdom know that when you give people something for nothing, you produce ungrateful people; that when you obscure the differences between men and women, you end up with many aimless men and angry women; that when you give children “self-esteem” without their earning it, you produce narcissists who enter adulthood often incapable of empathy and of handling life; that if you do not destroy evil, it will proliferate; and that if you are kind to the cruel, you will end up being cruel to the kind. If you really want goodness to prevail, wisdom is a key to unlocking it. The heart is not.”
