There is no neccesary reason why something should be contained, in fact contention was something we invented to refer to our observations: that people are contained in a society, that electrons are contained in a circuit... But contention about itself is not neccesary, only some sets do. But I think that a world were nothing is grouped, is not a world for a world is simply a group of all things. Therefore, we need to group things up together in order to understand, explain and rpedict the universe, this is what all our methods are based (scientific or not): induction, deduction, evaluation, critique, dialectics, research... |
