credo quia absurdum est

I believe it because it is absurd


A very common misquote of Tertullian's et mortuus est Dei Filius prorsus credibile quia ineptum est (and the Son of God is dead: in short, it is credible because it is unfitting), meaning that it is so absurd to say that God's son has died that it would have to be a matter of belief, rather than reason. The misquoted phrase, however, is commonly used to mock the dogmatic beliefs of the religious (see fideism). This phrase is commonly shortened to credo quia absurdum, and is also sometimes rendered credo quia impossibile est (I believe it because it is impossible) or, as Darwin used it in his autobiography, credo quia incredibile.
