To revolt is a natural tendency of life. Even a worm turns against the foot that crushes it. In general, the vitality and relative dignity of an animal can be measured by the intensity of its instinct to revolt.

Everything that lives, does so under the categorical condition of decisively interfering in the life of someone else.

The freedom of all is essential to my freedom.

From the naturalistic point of view, all men are equal. There are only two exceptions to this rule of naturalistic equality: geniuses and idiots.

The peoples' revolution... will arrange its revolutionary organisation from the bottom up and from the periphery to the centre, in keeping with the principle of liberty.

We must spread our principles, not with words but with deeds, for this is the most popular, the most potent, and the most irresistible form of propaganda.

Man is only truly free only among equally free men.
