There is a special pleasure in the irony of a moralist brought down for the very moral failings he has condemned. It’s the pleasure of a well-told jo… - Jonathan Haidt

Like Plato, Kant believed that human beings have a dual nature: part animal and part rational. The animal part of us follows the laws of nature, just as does a falling rock or a lion killing its prey. There is no morality in nature; there is only causality. But the rational part of us, Kant said, can follow a different kind of law: It can respect rules of conduct, and so people (but not lions) can be judged morally for the degree to which they respect the right rules. What might those rules be? Here Kant devised the cleverest trick in all moral philosophy. He reasoned that for moral rules to be laws, they had to be universally applicable. If gravity worked differently for men and women, or for Italians and Egyptians, we could not speak of it as a law. But rather than searching for rules to which all people would in fact agree (a difficult task, likely to produce only a few bland generalities), Kant turned the problem around and said that people should think about whether the rules guiding their own actions could reasonably be proposed as universal laws. If you are planning to break a promise that has become inconvenient, can you really propose a universal rule that states people ought to break promises that have become inconvenient? Endorsing such a rule would render all promises meaningless. Nor could you consistently will that people cheat, lie, steal, or in any other way deprive other people of their rights or their property, for such evils would surely come back to visit you. This simple test, which Kant called the “categorical imperative,” was extraordinarily powerful. It offered to make ethics a branch of applied logic, thereby giving it the sort of certainty that secular ethics, without recourse to a sacred book, had always found elusive.

The two biggest causes of evil are two that we think are good, and that we try to encourage in our children: high self-esteem and moral idealism. Having high self-esteem doesn’t directly cause violence, but when someone’s high esteem is unrealistic or narcissistic, it is easily threatened by reality; in reaction to those threats, people — particularly young men — often lash out violently.

Eliade’s most compelling point, for me, is that sacredness is so irrepressible that it intrudes repeatedly into the modern profane world in the form of “crypto-religious” behavior. Eliade noted that even a person committed to a profane existence has privileged places, qualitatively different from all others — a man’s birth-place, or the scenes of his first love, or certain places in the first foreign city he visited in his youth. Even for the most frankly nonreligious man, all these places still retain an exceptional, a unique quality; they are the “holy places” of his private universe, as if it were in such spots that he had received the revelation of a reality other than that in which he participates through his ordinary daily life.
