Historical always change moves in the direction of providing greater freedom for the individual

The future is completely unpredictable

There will always class divisions in society, with some people being oppressed by others

Historical change flows from changes in the way a society organises itself so as to make the necessities of life

Which best describes the view of Marx?

(2) is wrong, because Marx thought that in the end the process of history would produce a communist society lacking in class division. He thought that a correct understanding of history would allow you to work out what will happen next - so (3) is wrong. Freedom for the individual comes only in the final development of the communist society, so (4) is misleading.

(1) seems to me to express one of his most interesting thoughts.
