There is no arguing with the pretenders to a divine knowledge and to a divine mission. They are possessed with the sin of pride they have yielded to the perennial temptation.
There are pretenders to piety as well as to courage.
Knowledge is of two kinds. We know a subject ourselves or we know where we can find information upon it.
