It is not history which uses men as a means of achieving - as if it were an individual person - its own ends. History is nothing but the activity of men in pursuit of their ends.
Nothing can have value without being an object of utility.
The ruling ideas of each age have ever been the ideas of its ruling class.
Revolutions are the locomotives of history.
The production of too many useful things results in too many useless people.
The history of all previous societies has been the history of class struggles.
