Pay no attention to the God behind the curtain, for God is just another Wizard from Oz, an object of our own desire and declaration. We want someone strong enough to protect us from death and friendly enough to compensate us for the sacrifices we make to the world around us. As such, God is the Wizard of Oz that we have created and perpetuated, an old man projected as an almighty force of eternal life and paradise, the illusion of our belief, the delusion of our religion.
We represent God to ourselves, not in accordance with the evidence available to us but in accordance with our wishes; in other words, we create God in our image, or at least in the image of our desires. Now we have three things to be ashamed of: (1) the desires that govern this operation, (2) our willingness to subordinate truth to happiness, and (3) our hubris in making ourselves the creator and God the creature. If we are not utterly shameless, we will do our best to distract attention, especially our own, from what is going on.
(Westphal, Suspicion and Faith, 62)
We need the persistence and curiosity of Toto to pull back the curtain and reveal ourselves as the old man pulling the levers and our religious systems functioning to distract attention from what is going on.
To assess the truth-value of religious doctrines does not lie within the scope of the present enquiry. It is enough for us that we have recognized them as being, in their psychological nature, illusions.
(Freud, The Future of an Illusion, p31)
