Especially among Christians in positions of wealth and power, the idea of reading the Gospels and keeping Jesus' commandments as stated therein has been replaced by a curious process of logic. According to this process, people first declare themselves to be followers of Christ, and then they assume that whatever they say or do merits the adjective "Christian".

It is, of course, one of the miracles of science that the germs that used to be in our food have been replaced by poisons.

There are two laws that we had better take to be absolute. The first is that as we cannot exempt ourselves from living in this world, then if we wish to live, we cannot exempt ourselves from using the world. If we cannot exempt ourselves from use, then we must deal with the issues raised by use. And so the second law is that if we want to continue living, we cannot exempt use from care.

But the sower going forth to sow sets foot into time to come, the seeds falling on his own place. He has prepared a way for his life to come to him, if it will. Like a tree, he has given roots to the earth, and stands free.

Categorical condemnation is the hatred of the mob. It makes cowards brave.

This can happen only after we have made a categorical refusal to kindness: to heretics, foreigners, enemies or any other group different from ourselves.

To be well used, creatures and places must be used sympathetically, just as they must be known sympathetically to be well known...The "animal scientist" to whom it is of no concern whether or not animals suffer will almost inevitably aid and abet the destruction of the decent old ideal of animal husbandry and, as a consequence, increase the suffering of animals. I hope that my country may be delivered from the remote, cold abstractions of university science.
