Introduction
In the last month or so, I have become more of a "fly on the wall" in different scientific groups on Facebook. It has been interesting to take a break from interaction for a while and simply observe it. Something that I have noticed come up quite often is that many Christians, when debating scientific evidence with skeptics, end up telling the skeptics that they do not accept the evidence based on their presuppositions of atheism. That is bad enough, but what is disturbing is that I have also witnessed Christians say this same thing (presupposition of atheism) to Christians who take a different perspective (specifically on the age of the universe or evolution). (I have been a victim of this myself but did not think much of it until I saw it committed against several other Christians in multiple groups by multiple people.) Included in the attacks on both the skeptic and the fellow Christian is (sometimes explicit and sometimes implicit) the claim that presuppositions cannot be set aside. This leads the attacking Christian to feel justified in cutting off discussion and no longer answering questions or challenges to their view, and consigning the questioner to damnation. Today, I want to address the idea that presuppositions cannot be set aside, for if this is false, then the attacker has a false sense of logical security in their decision to be dismissive in the face of challenges they cannot (or will not) address.
