Those who are led by religious enthusiasts to expect a miraculous conversion of mankind to goodwill peace and wisdom overnight, expect the impossible and are preparing themselves for bitter disappointment. Human character grows gradually; it does not improve by magical transformation. It is better to be realistic, to face the unpalatable truth, than to surrender ourselves to wishful thinking and be deceived thereby. For emotion and passion are still the real rulers of mankind, say what you will.
