Human knowledge is not (or does not follow) a straight line, but a curve, which endlessly approximates a series of circles, a spiral. Any fragment, segment, section of this curve can be transformed (transformed one-sidedly) into an independent, complete, straight line, which then (if one does not see the wood for the trees) leads into the quagmire, into clerical obscurantism (where it is anchored by the class interests of the ruling classes). ---Lenin
人類的知識不是（或不遵循）一條直線，而是一條曲線，它不斷地接近一係列圓，螺旋。這條曲線的任何片段，分部，節可以轉化（轉化片麵）成為一個獨立的，完整的，直線的，然後（如果見木不見林）帶領入泥潭，到蒙昧主義（它是由統治階級的階級利益）固定。
 I did labor works, but mainly due to my idealism, not only I defy difficulty, but I conquered. This morning I saw the reddest sky 朝霞滿天紅，"看,無數的旗幟滿天飛舞" --馬雅可夫斯基
