Limits of language

Although math, logic, and language are very useful, I no longer think metaphysics really possible. I think however we need metaphors. We need some way to think about the world. Math, logic and language are the best tools we have to arrive at these metaphors. I am still trying to understand Principia Mathematica (by Alfred North Whitehead and Bertrand Russell) better. Also I want to especially study Whitehead more – especially his middle period more.
