I apologize in advance if this doesn't come out coherently. I drink maybe one or two nights a month, and that night is tonight.
Pure reason is useful to explore thought experiments where empirical inquiry is (currently) of limited use. Yet, it's usefulness is limited - and if reason leads you to conclusions that can't pass the giggle test, then you shouldn't take your conclusions too seriously without something concrete to back them up. At that point, labeling them as "truth" is... overly ambitious.
