It is more than forty years since my higher education began, and in that time there have been hundreds who have influenced me—Plato and Aristotle, Confucius and Buddha, Epictetus and Aurelius, Hobbes and Descartes, Kazantzakis, Orwell, Piaget, and many others. But in retrospect a few have had a special impact on my thought, and for them I feel the greatest affinity. All are from the Western philosophical or scientific tradition, the only tradition about which I’m qualified to make good judgments. I list them in the order I encountered their thought.
Will Durant – I always love reading this wonderful prose stylist; you sense his presence on all pages. What shines forth is his intellect, integrity, and decency. I would have liked to have known him, and if I had one biography to write it would be of him and his beloved wife Ariel. I grow nostalgic thinking of those stacks of books in my undergraduate library where I found him so long ago. I’m glad he was there.
Bertrand Russell’s Why I am Not A Christian awoken me from my dogmatic slumber when I was still a teenager. I think Russell was the greatest philosopher of the 20th century and— measured by his vast contributions to so many different fields from logic and mathematics to politics and ethics, and from his literary contributions to popular philosophy—he may have been the greatest philosopher in the history of Western tradition.
David Hume – I would loved to have been with Hume and Franklin in the salons of Paris, sipping brandy, gossiping, and flirting with the ladies! I admire the brave and honest skepticism of this fearless intellect. He was an good, honest, and courageous man, who faced death bravely, and he was more noble than most of his detractors, past or present. “Be a philosopher but be still a man,” he advised, and then lived up to his credo.
Carl Sagan instilled in me a love of science and clear thinking—the only means that we have to educe truth from reality. He knew that disregarding reason and evidence invites superstition, folly, and atrocities—a demon-haunted world. His moral concerns were for his fellow human beings, as well as the planet and cosmos from which they sprang. How I miss his principled and articulate voice in our selfish, reckless and irrational times.
E. O. Wilson taught me many lessons—that human behavior has biological roots; that nothing makes sense except in the light of evolution; that the biosphere is our only home; that most people would rather believe than know; that the evolutionary epic is the grandest narrative that we will ever have; and that we must direct the course of our future evolution. He is a great scientist, a man filled with childlike wonder for the natural world.
Charles Darwin – Darwin may have been the most influential person in human history. Today multiple sciences converge on his basic insight—which is true beyond any reasonable doubt. He gave us the greatest idea we have, and perhaps will ever have, an idea applicable to everything from the cell to the cosmos. Without a basic understanding of evolution, one lives in intellectual darkness. Before encountering Darwin that’s where I lived, and I thank him for showing me the light.
