Current research

What is the goal of science? What are the features that a good scientific theory ought to have, or ought not have? The most intuitive answers (e.g. the goal of science is to "find the truth") simply don't work. I'm trying to find better answers, drawing lessons from formal logic as well as from the particular sciences (especially physics). In particular, I've decided to take the contrarian gamble that Niels Bohr might have had at least one interesting idea, of lasting value, about what science could be. I'm also investigating the conceptual roots of Bohr's viewpoint, such as Kierkegaard's account of objectivity. ("No philosopher really understands what one means by the complementary description ... they did not see that it was an objective description." Bohr 1962)
