What's the METHOD in philosophic research? Don't tell me, please, that it's logic or the principle of inconsistency. The logic can be applied to all kinds of thinking: scientific, religious, philosophic, and even artistic. What I mean by METHOD is something like case-control or cohort methodology in scientific research. Is there any methodology in philosophic research? Do philosophers conduct any research for testing their propositions/hypotheses with some kinds of evidence? How? Which kind of evidence are they concerned about? How much evidence is enough for approving or refuting a hypothesis?
