From the mind there can be no escape. A simple notion can influence, until we’re a daze in thought. Yet, some thoughts are so complex and run so long they are able to penetrate the core of the mind from which they spring. Some realizations so ultimate they might even revoke our sense of self. For even when we are lost in thought do we rarely understand the truth, that we are lost to thought. Here the BBC covers exactly that in a documentary entitled Dangerous Knowledge. The film covers a group of geniuses who each ended their quest for knowledge in suicide.
