"The struggle of the people in opposition to the privileged class that controls the state, is the dynamic factor in our national development, the theme and meaning of our history."

"We cannot understand the role of the people in history unless we also understand the historical illusions which misrepresent history in order to serve the interests of privileged classes. Thus culture must be studied as a weapon in the struggle of classes.

"Cultural history emerges in its truth and grandeur when it is seen as an unceasing struggle between the oppressor and the oppressed. This is also the link between the present and the past. The long battle against the oppressor is not ended. Man has not yet become the full master of his own life, of the conditions of his social existence.

John Howard Lawson, The Hidden Heritage, 1950
