Context: I have not read Nietzsche or Ibsen, nor any other philosopher, and have not needed to do it, and have not desired to do it; I have gone to the fountain-head for information—that is to say, to the human race. Every man is in his own person the whole human race, with not a detail lacking. I am the whole human race without a detail lacking; I have studied the human race with diligence and strong interest all these years in my own person; in myself I find in big or little proportion every quality and every defect that is findable in the mass of the race. I knew I should not find in any philosophy a single thought which had not passed through my own head, nor a single thought which had not passed the heads of millions and millions of men before I was born; I knew I should not find a single original thought in any philosophy, and I knew I could not furnish one to the world myself, if I had five centuries to invent it in. Nietzsche published his book, and was at once pronounced crazy by the world—by a world which included tens of thousands of bright, sane men who believed exactly as Nietzsche believed, but concealed the fact, and scoffed at Nietzsche. What a coward every man is! and how surely he will find it out if he will just let other people alone and sit down and examine himself. The human race is a race of cowards; and I am not only marching in that procession but carrying a banner.
