"Every philosophy is a foreground philosophy--that is a hermit's judgment: "There is something arbitrary in his stopping _here_ to look back and look around, in his not digging deeper _here_ but laying his spade aside; there is also something suspicious about it." Every philosophy also _conceals_ a philosophy; every opinion is also a hide-out, every word also a mask." (Nietzsche. Beyond Good and Evil. 289)
「あらゆる哲学は前景哲学であり、それは隠者の下す判断だ。恣意的なところがある。なぜ「ここ」で立ち止まり、後ろを振り返り、あたりを見回し、これ以上は掘り下げず、鍬を置くのか。疑いを抱くところでもある。あらゆる哲学はべつの哲学を隠し持ってもいる。あらゆる意見は隠れ蓑でもあり、あらゆる言葉は仮面でもある。」（ニーチェ『善悪の彼岸』）
