Break down

It just feels like philosophy is the study of where our regular ways of justifying and understanding the world simply break down. At a sufficiently fundamental level, we no longer are able to use our normal methods for figuring out what's true and what's not. So we have to take linguistic frameworks for granted, be pragmatic, appeal to the inescapable, or refer to fundamental beliefs that we are stuck with. One of the things that philosophy is, is the attempt to figure out what the hell to do when our normal ways of dealing with problems implode.
