Abstract

Biologists are remarkably visual people. Yet, the classics of logical empiricism never raised the general question of scientific illustration. Moreover, one suspects that the silence was, if anything, actively hostile. People did not talk about biological illustration, because they did not judge it to be part of “real science”. This enterprise produces statements or propositions, ideally embedded in a formal system. It may beaboutthe real world, but it is not in any senseofthe real world, in being a copy or mirror image. Philosophers recognized that regretfully human weakness demanded the visual. But it was judged at best a prop. (See, for instance, Braithwaite 1953, Hempel 1965, and Bunge 1967; although see also Achinstein 1968. The best discussion of scientific illustration that I know is Rudwick 1976.)
