I'm sure that, for almost any position I take on a controversial political issue, there is an expert out there who has investigated it more than I have and, as a result, rejected my position -- or who *would* reject my position *if* they investigated it more thoroughly. (Take, for example, the question of whether Obamacare is good public policy.) This humbles me and makes it difficult for me to be fully confident in my conclusions and work up the motivation to fight for what seems like the right thing.
More generally, careful reflection on how I could be wrong often removes or severely diminishes the passion I might have originally felt about a political issue. My reflection breeds a sort of apathy.
Is that inappropriate? How do philosophers who passionately fight for political causes deal with the uncertainty that they could be wrong, or with the fact that there is (or could be) someone out there who is more of an expert *and* has the opposite view?
