There is in fact no such thing as art for art's sake, art that stands above classes, art that is detached from or independent of politics. Proletarian literature and art are part of the whole proletarian revolutionary cause.
Mao ZedongThis army is powerful because all its members have a conscious discipline; they have come together and they fight not for the private interests of a few individuals or a narrow clique, but for the interests of the broad masses and of the whole nation. The sole purpose of this army is to stand firmly with the Chinese people and to serve them whole-heartedly.
Mao ZedongRevolutions and revolutionary wars are inevitable in class society, and without them it is impossible to accomplish any leap in social development and to overthrow the reactionary ruling classes and therefore impossible for the people to win political power.
