When the foundations of social life are corroded, what ensues are battles over conflicting interests, new forms of violence and brutality, and obstacles to the growth of a genuine culture of care for the environment.

Nature appears to have been the cruel stepmother rather than the mother of many animals.

Animals will be seen on the earth who will always be fighting against each other with the greatest loss and frequent deaths on each side. And there will be no end to their malignity; by their strong limbs we shall see a great portion of the trees of the vast forests laid low throughout the universe; and, when they are filled with food the satisfaction of their desires will be to deal death and grief and labour and wars and fury to every living thing; and from their immoderate pride they will desire to rise towards heaven, but the too great weight of their limbs will keep them down.

Truly man is the king of beasts, for his brutality exceeds them. We live by the death of others. We are burial places.

You can chain me, you can torture me, you can even destroy this body, but you will never imprison my mind.

The greater the state, the more wrong and cruel its patriotism, and the greater is the sum of suffering upon which its power is founded.
