Wikiquote:Quote of the day/February 1, 2013
Any concepts or words which have been formed in the past through the interplay between the world and ourselves are not really sharply defined with respect to their meaning: that is to say, we do not know exactly how far they will help us in finding our way in the world. … It will never be possible by pure reason to arrive at some absolute truth. |
