I'm a dilettante. My governing word is 'curiosity.'

I have this extraordinary curiosity about all subjects of the natural and human world and the interaction between the physical sciences and the social sciences.

The word 'revolution' first brings to mind violent upheavals in the state, but ideas of revolution in science, and of political revolution, are almost coeval. The word once meant only a revolving, a circular return to an origin, as when we speak of revolutions per minute or the revolution of the planets about the sun.

Kant taught us that we should follow just those rules of conduct that we would want everybody to follow. Few find this generalization of The Golden Rule a great help.

The anti-Darwin movement has racked up one astounding achievement. It has made a significant proportion of American parents care about what their children are taught in school.

Labels such as ‘‘the culture wars,’’ ‘‘the science wars,’’ or ‘‘the Freud wars’’ are now widely used to refer to some of the disagreements that
plague contemporary intellectual life ... But I would like to register a gentle protest. Metaphors influence the mind in many unnoticed ways. The willingness to describe fierce disagreement in terms of the metaphors of war makes the very existence of real wars seem more natural, more inevitable,
more a part of the human condition. It also betrays us into an insensibility toward the very idea of war, so that we are less prone to be aware of how totally disgusting real wars really are.
