The peasants alone are revolutionary, for they have nothing to lose and everything to gain. The starving peasant, outside the class system, is the first among the exploited to discover that only violence pays. For him there is no compromise, no possible coming to terms. 

All revolutions devour their own children.

Revolutions never go backward.

Those who make peaceful revolution impossible will make violent revolution inevitable.

All men recognize the right of revolution, that is, the right to refuse allegiance to, and to resist, the government, when its tyranny or its inefficiency are great and unendurable.

The only justification of rebellion is success.

Revolutions are not made by men in spectacles.

The brutalities of progress are called revolutions. When they are over we realize this: that the human has been roughly handled, but that it has advanced.

This country, with its institutions, belongs to the people who inhabit it. Whenever they shall grow weary of the existing government, they can exercise their constitutional right of amending it, or their revolutionary right to dismember or overthrow it.
