Karl Marx (1818-1883) wrote this work (of which this edition only contains excerpts; the entire huge work was more than 700 pages, and mostly consisted of critiques of 19th century writers who are now forgotten) in 1845-1846, but it was never published in his lifetime.
All of Part I (on Ludwig Feuerbach) is included in this edition, wherein he states that communism is not "an ideal to which reality [will] have to adjust itself... (but) the REAL movement which abolishes the present state of things." (Pg. 56-57)
He says that Liberation is "an historical and not a mental act, and it is brought about by historical conditions..." (pg. 61). He argues that private property must be abolished, "because the contradicton between the classes has reached its extreme limit." (Pg. 117)
It is certainly not one of Marx's "major" works (e.g., compared to Poverty of Philosophy, written only a few years later), but will still be of some interest to those interested in the development of Marx's thought.
