(quote from RealReality.org/Real_Faith_and_Reason_Vol_2_-_Scientia.pdf)

Assumption-based thinking is amazingly versatile since, once an ungodly thinker accepts reasoning based on made-up stuff, this ungodly thinker can prove anything the ungodly thinker wants to believe. If an ungodly thinker accepts made-up stuff as proof, then the ungodly thinker can use made-up stuff as proof to “prove” that we should accept made-up stuff as proof. Yes. That logic is insane because it’s circular. And made-up stuff can also “prove” that divine revelation can’t be proof. Anything goes in this make-believe world of an insane person. And ungodly thinkers find this insane logic handy when they want to question the truth they hate but also want to avoid questioning the lies they love.
