人们常常怀疑笼统地提出“什么是人”这一问题是否科学。某些哲学家提过这问题,然而,这是一个虚幻的问题,马克思主义不可能提出这样的问题。不同的专门学科探索着人的活动的不同方面;没被探索的方面还没有;所有的“专门”学科一起描绘出一幅人的完整图象。另一方面,抽象的人是不存在的;只有具体社会的具体的人:奴隶主和奴隶,地主和农奴,资产阶级和无产者。 People often suspect that the question of whether “what is human beings” is a general one. Some philosophers mention this issue, however, which is an illusory issue that Marxism can not raise. Different specialized disciplines explore different aspects of human activity; none remain unexplored; all “specialized” disciplines together present a complete picture of one person. On the other hand, abstract people do not exist; there are only concrete people in specific societies: slave owners and slaves, landlords and serfs, bourgeoisie and proletarians.
