I have come to believe that all thoughts have been thought before somewhere by someone. Therefore, it is impossible to have an original thought by thinking. I think that there are (and, more importantly, have been) so many people in the world pondering the ponderous that there is now no route of ponderance left un-pondered.

Infact, I believe this very theory will have been thought before by someone before now.

I don’t mean that they thought it in these exact words or this exact form, but someone will have thought this at some point.
