Repression for the attainment of economic ends is a necessary weapon of the socialist dictatorship. - Leon Trotsky

As a general rule, man strives to avoid labor. Love for work is not at all an inborn characteristic: it is created by economic pressure and social education. One may even say that man is a fairly lazy animal. It is on this quality, in reality, that is founded to a considerable extent all human progress; because if man did not strive to expend his energy economically, did not seek to receive the largest possible quantity of products in return for a small quantity of energy, there would have been no technical development or social culture.

The permanent revolution, in the sense which Marx attached to this concept, means a revolution which makes no compromise with any single form of class rule, which does not stop at the democratic stage, which goes over to Socialist measures and to war against reaction from without; that is, a revolution whose every successive stage is rooted in the preceding one and which can end only in the complete liquidation of class society.

Natasha and I said more than once that one may arrive at such a physical condition that it would be better to cut short one's own life or, more correctly, the too slow process of dying … But whatever may be the circumstances of my death I shall die with unshaken faith in the communist future. This faith in man and in his future gives me even now such power of resistance as cannot be given by any religion.
