German philosopher (and Habermas' important interlocutor) Ernst Tugendhat on religion as a need and the difficulty of satisfying it
"Faust avoided Gretchen's question "Do you believe in God?" But what should someone say who refuses to avoid the question and yet isn't naive? I believe that on the one hand the need to believe in God is not only a cultural, but also an anthropological phenomenon, founded in the structure of human being. Today, however, people can't give in to this need without fooling themselves. What we have here is a contradiction between need and feasibility. Seen logically, such contradictions are harmless, and relatively normal in human life.
Let me clarify this with an example. People – at least in general – have a need to go on living. That too is anthropologically founded. Yet this need stands in contradiction to reality: all individual life ceases to exist after a time. However the need to go on living is so deeply rooted that people in all cultures have attempted in one way or another, with or without religion, to construct a life after death."
