That's what Ludwig Wittgenstein, a great philosopher said.
This statement is very bold to make. I find it very interesting, and partly agree with it at the moment. I just think, sometimes, we escape from the language into a feeling phase. And I think one could think while feeling, not needing to use any language, rather solely use emotions. I hope I expressed myself clearly, it's very complicated to try and describe this idea. One is most certainly limited by the language while writing.
I have to contemplate on it a little more however... What do you think?
