Why should we teach Chemistry and Art? We teach it to promote an attitude of mind, an approach to solving problems that is disappearing today. As scientists, we assemble all available evidence and we evaluate it critically: that done, we draw those conclusions that fit the evidence and we reject others that do not. That is what we must teach.

Art is treasured everywhere: science increasingly is not. Nevertheless we can teach non-scientists how the scientific examination of art increases their understanding of art. They witness science in action and what a scientific approach can achieve. Scientists, too, studying chemistry and art, see how science benefits art, as they themselves are introduced to art.

Art provides the lure to teach scientific reasoning. Our society faces a crisis in values. We must insist on honest reasoning and teach it widely. How else are we to evaluate global warming?
