It was Dostoevsky, once again, who drew from the French Revolution and its seeming hatred of the Church the lesson that “revolution must necessarily begin with atheism.” That is absolutely true. But the world had never before known a godlessness as organized, militarized, and tenaciously malevolent as that practiced by Marxism. Within the philosophical system of Marx and Lenin, and at the heart of their psychology, hatred of God is the principal driving force, more fundamental than all their political and economic pretensions. Militant atheism is not merely incidental or marginal to Communist policy; it is not a side effect, but the central pivot.
Ultimately, on materialism, everything boils down to matter in motion. Making value judgments about matter in motion is meaningless. But if everything is matter in motion, then there doesn’t seem to be any way to make value judgments. How does one value a rock over a stick? They’re both just stuff. But then, on materialism, people are just stuff too; albeit more complex. However, if you were to break us down into our ultimate realities, we are no different than the rock. We are matter organized in a different way. Why value us? There is no objective reason to do so. Therefore, there is no objective meaning or value. Life is purposeless, meaningless, valueless. Atheistic materialism demands this bleak view of the universe.
