I am convinced that its realisation is a certainty in the course of human development. Our social institutions are founded on certain ideas - as long as the latter are generally believed, the institutions built on them are safe.
Government remains strong because people think political authority and legal compulsion necessary.
Capitalism will continue as long as such an economic system is considered adequate and just. The weakening of the ideas which support the evil and oppressive presentday conditions means the ultimate breakdown of government and capitalism. Progress consists in abolishing what man has outlived and substituting in its place a more suitable environment. It must be evident even to the casual observer that society is undergoing a radical change in its fundamental conceptions. The World War and the Russian Revolution are the main causes of it.
