learn what it costs to have legs of clay. To overthrow idols (idols is the name I give to all ideals) is much more like my business. In proportion as an ideal world has been falsely assumed, reality has been robbed of its value, its meaning, and its truthfulness.... The "true world" and the "apparent world"—in plain English, the fictitious world and reality.... Hitherto the lie of the ideal has been the curse of reality; by means of it the very source of mankind's instincts has become mendacious and false; so much so that those values have come to be worshipped which are the exact opposite of the ones which would ensure man's prosperity, his future, and his great right to a future.

He who knows how to breathe in the air of my writings is conscious that it is the air of the heights, that it is bracing. A man must be built for it, otherwise the chances are that it will chill him. The ice is near, the loneliness is terrible—but how serenely everything lies in the sunshine! how freely one can breathe! how much, one feels, lies beneath one! Philosophy, as I have understood it hitherto, is a voluntary retirement into regions of ice and mountain-peaks—the seeking—out of everything strange and questionable in existence, everything upon which, hitherto, morality has set its ban. Through long experience, derived from such wanderings in forbidden country, I acquired an opinion very different from that which may seem generally desirable, of the causes which hitherto have led to men's moralising and idealising. The secret history of philosophers, the psychology of their great names, was revealed to me.

Error (the belief in the ideal) is not blindness; error is cowardice.... Every conquest, every step forward in knowledge, is the outcome of courage, of hardness towards one's self, of cleanliness towards one's self. I do not refute ideals; all I do is to draw on my gloves
