“Anyone who truly wants to escape human solipsism should not seek out empty places. Instead of fleeing to desert, where they will be thrown back into their own thoughts, they will d better to seek out the company of other animals. A zoo is a better window from which to look out of the human world than a monastery.”

“Christianity's goal is not escape from this world. It loves this world and seeks to change it for the better.”

“Should we only look ourselves?' Rehman said finally. 'Aren't humans better than animals who think only of their own hunger and thirst and feed just their own children?”

“Respect what is human in everyone, seek it out and create it...The true citizen of the future is he who is free from prejudice and convention, who does not fear for himself and does not fear the misunderstanding of others, who places above all else in life the marvellous emotion of love and the happiness of untrammelled creativity. That is the humanity for which I died.”

“And people who believe in God think God has put human beings on earth because they think human beings are the best animal, but human beings are just an animal and they will evolve into another animal, and that animal will be cleverer and it will put human beings into a zoo, like we put chimpanzees and gorillas into a zoo. Or human beings will all catch a disease and die out or they will make too much pollution and kill themselves, and then there will only be insects in the world and they will be the best animal.”

“A good zoo is a place of carefully worked-out coincidence: exactly where an animal says to us, "Stay out!"...we say to it, "Stay in!" with our barriers. Under such conditions of diplomatic peace, all animals are content and we can relax and have a look at each other.”
