Marxist learning about man is a kind of science about real man and his history. On the basis of real man’s definition

Marx constructed his own system of learning about man

which was different from the others. Man being man is not because he is living being

but because he is social existence. So

Marx especially emphasize man’s social essence. Real man comes into being and develops in the process of material production

which is concrete and historical

and consistence of natural existence and social existence

and includes living individual existence

real man’s material living conditions and real man’s actions. Thus

Marxist learning about man looks on man’s practice--material production--as the basis of all changes in real world

only on which we can build the scientific system of Marxist learning about man.
