Secular Humanists/Naturalists presuppose a priori that the existence and activity of non-material, incorporeal, spirit beings are not possible. Like a First Order Skeptic argues that one cannot be sure of anything beyond perception, the Secularist accepts existence of all that is material while rejecting any spiritual realm. The dissertation qualitatively ties together themes arguing that the same standards secularists apply to vetting any commonly accepted historical event whatever also inductively supports the existence and activity of demons.
