The great philosophers of history were those that truly practiced the love of knowledge.
It was Martin Luther who, as a theologist, recognized the failures of organizing society according to catholic doctrine. It was Galileo Galilei who, as an astronomer, recognized our world was just one of many. It was Darwin who, as a biologist, recognized that the reason we exist is life's perpetual struggle for survival. It was Einstein who, as a physicist, recognized that the 2 main aspects of our perceived reality are intermingled.
