Abstract
If classics of science were to be defined as works that mark scientific revolutions, in the sense of sharp shifts in research tradition, then none of the three works discussed in our symposium quite qualifies. I briefly indicate the fate of each. While impressed by his argument, I express some reservations about Lennox's claim to have dissolved the "problem of demonstration" for Aristotle's De Partibus Animalium. I question Finocchiaro's challenging assertion that in structuring the Dialogo as he did, Galileo "operated within the restrictions" laid on him. Finally, I argue that the legacy of Newton's Opticks was in crucial respects a divided one for the generations that followed.
