When I see the blind and wretched state of men, when I survey the whole universe in its deadness, and man left to himself with no light, as though lost in this corner of the universe without knowing who put him there, what he has to do, or what will become of him when he dies, incapable of knowing anything, I am moved to terror, like a man transported in his sleep to some terrifying desert island, who wakes up quite lost, with no means of escape. Then I marvel that so wretched a state does not drive people to despair.

Atheism shows strength of mind, but only to a certain degree.

If there is a God, He is infinitely incomprehensible, since, having, neither parts nor limits, He has no affinity to us. We are then incapable of knowing either what He is or if He is. [So] you must wager. Let us weigh the gain and the loss in wagering that God is. Let us estimate these two chances. If you gain, you gain all; if you lose, you lose nothing. Wager then without hesitation that he is.

The statements of atheists ought to be perfectly clear of doubt. Now it is not perfectly clear that the soul is material.
