Does anyone else find it unreasonable to have ◊P in modal logic? -

Re: Possibility in modal logicI know nothing about formal logic, but as far as I can tell you're questioning whether the possibility is a meaningfull predicate--am I right? It obviously doesn't behave in the same way as normal predicates; but could not propositions about possibility be reduced to conditional propositions about existence?
