“Instead of accepting revelation they became philosophers. And what is a philosopher? A philosopher is a man who claims that he starts by being skeptical about everything, that he is an agnostic. ‘I am going to have the data,’ he says, ‘and then I am going to apply my mind to it. I am going to reason it out and I am going to work it out.’ And that is exactly what such men have done; they became foolish and wicked in their reasonings, in their thoughts, in their own conjectures and speculations and surmisings. And what is the cause of it all? Paul uses the word ‘vain’ and it means not only foolish, but it means wicked as well. . . . The cause of the whole trouble was wickedness, and it is still wickedness.’”
