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?
Philosophy does not have a distinctive method. The subject is better characterised in terms of the problems it addresses than in terms of the methods it uses. But in philosophy we do often find ourselves in the situation where the question seems genuine but there is no straightforward procedure for answering. (Some might even be tempted to define a philsophical problem in this way: real questions with no clear way to determine answers.) The questions seem neither straightforwardly empirical, nor susceptible to anything like proof. So we scrabble around as best we can, clarifying, articulating, and checking for consistency and coherence.
