Friedrich Nietzsche, Beyond Good and Evil, Aphorism 146

Wer mit Ungeheuern kämpft, mag zusehn, dass er nicht dabei zum Ungeheuer wird. Und wenn du lange in einen Abgrund blickst, blickt der Abgrund auch in dich hinein.  

He who fights with monsters should look to it that he himself does not become a monster. And if you gaze long into an abyss, the abyss also gazes into you.   




Beyond Good and Evil, Aphorism 146

황동규 즐거운 편지

1

​

내 그대를 생각함은 항상 그대가 앉아 있는 배경에서

해가 지고​ 바람이 부는 일처럼 사소한 일일 것이나

언젠가 그대가 한없이 괴로움 속을 헤매일 때에

오랫동안 전해 오던 그 사소함으로 그대를 불러 보리라

​

​

진실로 진실로 내가 그대를 사랑하는 까닭은

내 나의 사랑을 한없이 잇닿은 그 기다림으로 바꾸어 버린데 있었다

밤이 들면서 골짜기엔 눈이 퍼붓기 시작했다

내 사랑도 어디쯤에선 반드시 그칠 것을 믿는다

다만 그때 내 기다림의 자세를 생각하는 것 뿐이다

그동안에 눈이 그치고 꽃이 피어나고 낙엽이 떨어지고 또 눈이 퍼붓고 할 것을 믿는다​

순수이성비판

내용 없는 사고는 공허하며, 개념 없는 직관은 맹목이다.(Gedanken ohne Inhalt sind leer, Anschauungen ohne Begriffe sind blind.) 

Platoon ending scene Chris Taylor's speech

Chris Taylor: I think now, looking back, we did not fight the enemy, we fought ourselves. The enemy was in us. The war is over for me now, but it will always be there, the rest of my days. As I'm sure Elias will be, fighting with Barnes for what Rhah called "possesion of my soul." There are times since, I've felt like a child, born of those two fathers. But be that as it may, those of us who did make it have an obligation to build again. To teach to others what we know, and to try with what's left of our lives to find a goodness and a meaning to this life.
