Left-libertarians, liberals, leftists, and atheists who live in Western countries oftentimes argue that reason alone can dictate morality. It is amusing, in my mind, that they can even suggest this, for they usually have lived most—if not all—of their lives in a Western country in which Christianity served as a major force in forging the society. Those who preach the importance of reason in judging what is moral cannot escape from the culture in which they were born, raised, and lived for much of their life, for beliefs that they hold are ingrained through culture in their hearts. The atheist, tradition-hating, coffeehouse fruitcakes of the 18th century—the philosophers of the Enlightenment—were wrong. What is considered to be moral cannot be judged by mere reason alone.more here.
