Some people say, therefore, that violence and war are inevitable. I say rubbish: Our brains are fully capable of controlling instinctive behavior.

For those who have experienced the joy of being alone with nature there is really little need for me to say much more; for those who have not, no words of mine can ever describe the powerful, almost mystical knowledge of beauty and eternity that come, suddenly, and all unexpected.

Cultural speciation had been crippling to human moral and spiritual growth. It had hindered freedom of thought, limited our thinking, imprisoned us in the cultures into which we had been born. . . . These cultural mind prisons. . . . Cultural speciation was clearly a barrier to world peace. So long as we continued to attach more importance to our own narrow group membership than to the ‘global village’ we would propagate prejudice and ignorance.

Farm animals feel pleasure and sadness, excitement and resentment, depression, fear, and pain. They are far more aware and intelligent than we ever imagined...they are individuals in their own right.
