“We introduced a new model of behavior: don't get involved in diffuse general ideological polemics with the center, to whom numerous concrete causes are always being sacrificed; fight "only" for those concrete causes, and be prepared to fight for them unswervingly, to the end. In other words, don't get mixed up in backroom wheeling and dealing, but play an open game.”

Disturbing the Universe (1979)
Context: A good cause can become bad if we fight for it with means that are indiscriminately murderous. A bad cause can become good if enough people fight for it in a spirit of comradeship and self-sacrifice. In the end it is how you fight, as much as why you fight, that makes your cause good or bad. <!-- Pt. 1, Ch. 4

Original: (ar) حَدَّثَنَا سُلَيْمَانُ بْنُ حَرْبٍ، حَدَّثَنَا شُعْبَةُ، عَنْ عَمْرٍو، عَنْ أَبِي وَائِلٍ، عَنْ أَبِي مُوسَى ـ رضى الله عنه ـ قَالَ جَاءَ رَجُلٌ إِلَى النَّبِيِّ صلى الله عليه وسلم فَقَالَ الرَّجُلُ يُقَاتِلُ لِلْمَغْنَمِ، وَالرَّجُلُ يُقَاتِلُ لِلذِّكْرِ، وَالرَّجُلُ يُقَاتِلُ لِيُرَى مَكَانُهُ، فَمَنْ فِي سَبِيلِ اللَّهِ قَالَ ‏ "‏ مَنْ قَاتَلَ لِتَكُونَ كَلِمَةُ اللَّهِ هِيَ الْعُلْيَا فَهُوَ فِي سَبِيلِ اللَّهِ ‏"‏‏.‏
