[1][2] The causes of revolutionary waves have become the subjects of study by historians and political philosophers, including Robert Roswell Palmer, Crane Brinton, Hannah Arendt, Eric Hoffer, and Jacques Godechot.
[3] Writers and activists, including Justin Raimondo and Michael Lind, have used the phrase "revolutionary wave" to describe discrete revolutions happening within a short time-span.
[9] A further dimension to Katz's typology[10] is that revolutions are either against (anti-monarchy, anti-dictatorial, anti-capitalist, anti-communist, anti-democratic) or for (pro-fascism, pro-liberalism, pro-communism, pro-nationalism etc.).
The advance, by leaps and bounds, of the intellectual stature of the proletariat affords an inviolable guarantee of its further progress in the inevitable economic and political struggles ahead.
[22] Mark Katz theorises that Buddhism (in Sri Lanka, Thailand, Indochina, Burma, Tibet) and Confucianism (to replace Marxism in China and promote unity with Chinese in Taiwan, Hong Kong, Singapore, Malaysia) might be the revolutionary waves of the future.
