How many people have thought through their most basic beliefs? Beliefs so obvious that you never bother to think about them and simply reason from them as a base. In fact rejecting them places you in an odd position leading to self-refutation, a house collapsing in on itself from internal weakness. Let’s look at just three:
- There are universal truths.
- There is but one universal logic.
- Reason can be trusted.
I have had many people argue with me at various times that one or more of the foregoing are in fact false. The most common is number one. There is no truth (except that statement is a truth claim).
The Nazi’s argued for polylogism as a means of dehumanizing their opposition and enhancing their claims of racial superiority. Marx argued for it between classes. Polylogism is nothing more than attempt to make myself immune from challenge. It permits me to silence you when I am losing the argument, you bourgeois pig.
The antithesis of three is typically found in a radical skeptic. But what did he use to arrive at that conclusion, divine revelation? It must be because reason cannot be trusted. Then again his reason cannot be sure it was divine revelation. We cannot use reason to determine that reason cannot be trusted any more than we can pull our drowning body out of the water with our own hair.
