“Nature is our book," [Aristotle] would say. "It is the most sacred text we have. Line by line, reason will unlock the mysteries of our world, and once we understand them it will change the way we think.”

“A few lines of reasoning can change the way we see the world.”

“Today we have a weakness in our education process in failing to understand the natural associations between the disciplines. We tend to study all our disciplines in unrelated parallel lines. This tends to be true in both Christian and secular education. This is one of the reasons why evangelical Christians have been taken by surprise at the tremendous shift that has come in our generation.”

“The truth is: the natural world is changing. And we are totally dependent on that world. It provides our food, water and air. It is the most precious thing we have and we need to defend it.”

“What kind of world would we create if three times a day we activated our compassion and reason as we sat down to eat, if we had the moral imagination and the pragmatic will to change our most fundamental act of consumption?”

“We but mirror the world. All the tendencies present in the outer world are to be found in the world of our body. If we could change ourselves, the tendencies in the world would also change. As a man changes his own nature, so does the attitude of the world change towards him. This is the divine mystery supreme. A wonderful thing it is and the source of our happiness. We need not wait to see what others do.”
