Sam Harris believes that morality can be worked out logically on scientific principles and I have no doubt it can but in my view this would lead to dogmatism, intolerance, cruelty and immorality. Morality, like the milk of human kindness, can only come from the heart and to believe otherwise is to diminish what man is and can lead to all kinds of nastiness. “The end justifies the means” is just one example of where this kind of thinking can take us.
