恩格斯在1890年9月致约·布洛赫的信中提出了著名的“历史合力论”。哲学论著都予以高度肯定,公认它揭示了历史创造和发展的一般规律,有的提出“合力规律在无产阶级社会中同样存在,它贯穿于人类社会的始终”,是“一条普遍的规律”。然而,笔者以为,恩格斯的“历史合力论”本身揭示的只是阶级社会的历史创造和发展规律。 Engels proposed the famous “theory of historical alliances” in Letter to J. Bloch in September 1890. Philosophy is highly affirmed, acknowledged that it reveals the history of the general law of creation and development, and some put forward the “law of forces in the same proletarian society exists, it runs through human society,” is “a universal law.” However, the author believes that Engels’s theory of “historical synergy” reveals only the law of historical creation and development of class society.
