No one revolution up to now has brought all that was expected of it by the masses. Hence the inevitability of a certain disillusionment, of a lowering of the activity of the vanguard, and consequently, of the growing importance of the rearguard.

Leon TrotskyLook back at history - those who guided the revolution in the time of its culmination never kept their leading positions long after the turning point.
Leon TrotskyAs for us, we were never concerned with the Kantian-priestly and vegetarian-Quaker prattle about the "sacredness of human life." We were revolutionaries in opposition, and have remained revolutionaries in power. To make the individual sacred we must destroy the social order which crucifies him. And this problem can only be solved by blood and iron.
