Abstract
Scientists often refer to their experiments, theories, images and instruments as beautiful and
report that their scientific work is a source of aesthetic experiences. How do such aesthetic
values affect scientific activities, and can aesthetic values play a cognitive role in science? In
this chapter, I identify the different levels at which aesthetic values shape scientific products
and processes, reflect on how philosophers have justified the cognitive role of such aesthetic
values, and draw insights from recent discussions on the aesthetics of scientific practice for the
values in science debate.
