“I don’t want to believe, I want to know.”

"I want everything" http://home.earthlink.net/~2lulah2/everything.htm in What I Want from Life (1934) edited by Edmund George Cousins, p. 108
Context: I don’t know what I want.
Nobody knows — or if they do, they don’t know for long. I mean, you don’t want the same thing long enough for it to be What You Want From Life in capital letters.
Well, maybe some people do. Maybe there's a few simple folks — or maybe a few million, I don't know — who fix their hearts, and their minds, and their everlasting souls on a thing, and keep on all their lives hoping for it. Living for it. Wanting It From Life.
But these are the people who never get it.

Context: In speaking of the fear of religion, I don’t mean to refer to the entirely reasonable hostility toward certain established religions and religious institutions, in virtue of their objectionable moral doctrines, social policies, and political influence. Nor am I referring to the association of many religious beliefs with superstition and the acceptance of evident empirical falsehoods. I am talking about something much deeper—namely, the fear of religion itself. I speak from experience, being strongly subject to this fear myself: I want atheism to be true and am made uneasy by the fact that some of the most intelligent and well-informed people I know are religious believers. It isn’t just that I don’t believe in God and, naturally, hope that I’m right in my belief. It’s that I hope there is no God! I don’t want there to be a God; I don’t want the universe to be like that.
