Complex organisms cannot be construed as the sum of their genes, nor do genes alone build particular items of anatomy or behavior by themselves. Most genes influence several aspects of anatomy and behavior—as they operate through complex interactions with other genes and their products, and with environmental factors both within and outside the developing organism. We fall into a deep error, not just a harmful oversimplification, when we speak of genes “for” particular items of anatomy or behavior.

In return for this great gift that I could not repay in a thousand lifetimes, at least I can promise that, although I have frequently advanced wrong, or even stupid, arguments (in the light of later discoveries), at least I have never been lazy, and have never betrayed your trust by cutting corners or relying on superficial secondary sources. I have always based these essays upon original works in their original languages (with only two exceptions, when Fracastoro's elegant Latin verse and Beringer's foppish Latin pseudocomplexities eluded my imperfect knowledge of this previously universal scientific tongue).

No more harmful nonsense exists than [the] common supposition that deepest insight into great questions about the meaning of life or the structure of reality emerges most readily when a free, undisciplined, and uncluttered (read, rather, ignorant and uneducated) mind soars above mere earthly knowledge and concern.

Darwin grasped the philosophical bleakness with his characteristic courage. He argued that hope and morality cannot, and should not, be passively read in the construction of nature. Aesthetic and moral truths, as human concepts, must be shaped in human terms, not “discovered” in nature. We must formulate these answers for ourselves and then approach nature as a partner who can answer other kinds of questions for us—questions about the factual state of the universe, not about the meaning of human life. If we grant nature the independence of her own domain—her answers unframed in human terms—then we can grasp her exquisite beauty in a free and humble way. For then we become liberated to approach nature without the burden of an inappropriate and impossible quest for moral messages to assuage our hopes and fears. We can pay our proper respect to nature's independence and read her own ways as beauty or inspiration in our different terms.
