The most important distinction, then, isn’t in separating artists from scientists and doctors, but in separating formulaic thinkers from creative ones, separating those who can tolerate uncertainty from those who cannot. Art, science, and medicine trade in doubt, and in its remedy – improvisation.

Science seeks to find truth in the natural world; art seeks to find truth in the emotional world.

For the artist, the goal of the painting or musical composition is not to convey literal truth, but an aspect of a universal truth that if successful, will continue to move and to touch people even as contexts, societies and cultures change. For the scientist, the goal of a theory is to convey truth for now–to replace an old truth, while accepting that someday this theory, too, will ve replaced by a new truth, because that is the way science advances.
