First post. I just have a question about identifying a fallacy.
Let's say you are talking to someone who believes the earth is 6,000 years old. You begin to present evidence that suggests the earth could not be 6,000 years old and the person responds that 'we just have different presuppositions' and further explains that you are listening to some experts while they are listening to others. They say you are just as biased about your beliefs as they are (Tu Quoque fallacy) and that it all depends on your 'worldview'.
So obviously we have a Tu Quoque in there but I'm not sure about this idea that everyone just has a 'starting point' and that affects everything. It seems to completely ignore the scientific method and treats evidence as if it's equivalent to bias. I'm thinking a Subjectivism Fallacy? Any thoughts?
