Ethics without virtue is an illusion. What is the highest purpose of ethics? It is to make a person good, that is virtuous.
Peter KreeftNo culture in history has ever embraced moral relativism and survived. Our own culture, therefore, will either (1) be the first, and disprove history's clearest lesson, or (2) persist in its relativism and die, or (3) repent of its relativism and live. There is no other option.
Peter KreeftSomeone once said that if you sat a million monkeys at a million typewriters for a million years, one of them would eventually type out all of Hamlet by chance. But when we find the text of Hamlet, we don't wonder whether it came from chance and monkeys. Why then does the atheist use that incredibly improbable explanation for the universe? Clearly, because it is his only chance of remaining an atheist. At this point we need a psychological explanation of the atheist rather than a logical explanation of the universe.
