It has become almost a cliche to remark that nobody boasts of ignorance of literature, but it is socially acceptable to boast ignorance of science and proudly claim incompetence in mathematics.

• Intelligent life on a planet comes of age when it first works out the reason for its own existence.
• I was confirmed at my prep school at the age of 13.
• When I say that human beings are just gene machines, one shouldn't put too much emphasis on the word 'just.' There is a very great deal of complication, and indeed beauty in being a gene machine.
• Design can never be an ultimate explanation for anything. It can only be a proximate explanation. A plane or a car is explained by a designer but that's because the designer himself, the engineer, is explained by natural selection.
• Personally, I rather look forward to a computer program winning the world chess championship. Humanity needs a lesson in humility.
• The universe we observe has precisely the properties we should expect if there is, at bottom, no design, no purpose, no evil, no good, nothing but blind, pitiless indifference.
• Design can never be an ultimate explanation for anything. It can only be a proximate explanation. A plane or a car is explained by a designer but that's because the designer himself, the engineer, is explained by natural selection.
• Segregation has no place in the education system.
• But perhaps the rest of us could have separate classes in science appreciation, the wonder of science, scientific ways of thinking, and the history of scientific ideas, rather than laboratory experience.
• Faith is the great cop-out, the great excuse to evade the need to think and evaluate evidence. Faith is belief in spite of, even perhaps because of, the lack of evidence.
