Rowe, William L. (1998). «Agnosticism». In Edward Craig (ed.). Routledge Encyclopedia of Philosophy. Taylor & Francis.

In so far as one holds that our beliefs are rational only if they are sufficiently supported by human reason, the person who accepts the philosophical position of agnosticism will hold that neither the belief that God exists nor the belief that God does not exist is rational.»
