Interesting that DeLaplante assumes a biological creature which has ‘evolved’ for the purpose of survival can know truth. Certainly our adapted faculties will help us to survive better than those of our predecessors, but is in no way our evolved brain a guarantor of known truth. In fact, since we are ‘evolved,’ we should not think that we actually can know anything.Welcome to the world of internet rationality geekage. It’s got its own customs. One of its customs is to always try to appear more rational than the other fellow, even if the other fellow does a podcast about critical thinking. Even if you have to resort to scorched-earth type lines about how human brains can’t get truth.
