The ultimate desire of the theistic mind is to be close to his conception of God. For the atheistic mind, the ultimate desire is to be God.
There is a contradiction in the mind of both, the theist and the atheist. Both are lusting for something that is unknowable and unachievable. But the desire of the atheist is more dangerous, because he wants to be the God, the secular, earthly, living God. What will a man not do when his aim is to be the God of all humans!
The philosopher of post-Bolshevik leftism, Jean-Paul Sartre, himself an outspoken atheist, understood the atheistic mind. Towards the end of his book Being and Time, he writes, “man is a being who wants to be God.”
