Who said, "Believe, but know your belief is absurd"?

In my limited experience with the humanities I recall being told that some philosopher’s message could be summarized thus: “Believe, but know that your belief is absurd.” I have come to the conclusion that this is the best attitude I can adopt with regard to the policies of my workplace, and I would like to give credit where credit is due. Can anyone identify this prescient software engineer?

Was it MEBuckner?

“There are two major products that come out of Berkeley: LSD and UNIX. We don’t believe this to be a coincidence.” - Jeremy S. Anderson
Always a good one.

“I do not feel obliged to believe that the same God who has endowed us with sense, reason, and intellect has intended us to forgo their use.” - Galileo Galilei
Getting closer.

“Man is a credulous animal, and must believe something; in the absence of good grounds for belief, he will be satisfied with bad ones.” - Russell Bertrand
Closer yet.

“A belief which leaves no place for doubt is not a belief; it is a superstition.” - Jose Bergamin
This was the best I could find.

With regard to Christianity, the early church father Tertullian wrote something to the effect of “It must be true because it is so absurd.”

That kind of sounds like David Hume to me.
