Racism is an avoidable culture clash masquerading as inescapable biological warfare. - Guy P. Harrison

Science is not the latest religion and scientists are not exalted priests. We have to think of science as a wonderful tool that is also dangerous. Using it requires responsibility. Science gives us vaccines one moment, nuclear warheads the next. It's up to us to be wise tool users.

Intelligent design is intellectual surrender. Not understanding how something works or how it came to be is not an answer. Our current ignorance should only be motivation to keep working the problems. Everything is irreducibly complex—until a scientist figures it out.

All known life on Earth today is fundamentally similar, is genetically related, and shares descent from a single-celled common ancestor that lived at least 3 or 4 billion years ago. . . . Sometimes I get so wrapped up in thoughts about evolution, biodiversity, and the surprisingly close relationships between lifeforms that I look around and see only slight variations of genetic code.
