Marx wrote an enormous number of books and articles, sometimes with his friend Friedrich Engels

马克思写了无数书记和论文，有时候会和的恩格斯一起发表。

This focus on labor gave rise to the perspective created by Marx and his longtime collaborator Friedrich Engels – a perspective known as historical materialism.

这种对劳动的关注催生了马克思和的长期合作者弗里德里希·恩格斯创造的观点——一种被称为历主义的观点。

But Marx had never really gone away, whereas Friedrich Engels the man who worked hand in glove with him for most of his life and made a huge contribution to " Das Kapital" - is almost forgotten.

其实，马克思从未真正离开。而弗里德里希.恩格斯，这个伴随大半生且对《资本论》诞生贡献巨大的挚——却几乎已被世人淡忘。
