text: please discuss? a skeptic approaches you regarding the up coming elections with the retort all politicians are liars. you do not believe your candidate is a liar and want to rebuke the skeptics claim. how could the square of opposition or the immediate inferences found through obversion, conversion and contraposition help you in your quest. i dont believe that our politicians are liars any more than anyone else.  they probably live more honestly than most.  anyhow, we live in whats known as a "representative republic".  that means our elected officials are chosen by whom best represents the people there, or at least the people that voted.  so, if you think all politicians are liars you can do two things:  1. be vocal about the fact that you want someone who is honest and will do what they say they will do (george w. bush did do that look it up) and 2. you vote.  people often get the leadership they deserve.
