I argue that Either/Or contains a proposal for philosophy of science, and in particular, about the ultimate goal of science (i.e., the ideal epistemic state). Whereas the Cartesian-Hegelian tradition conceived of the ideal state as one of detached reflection – that is, “seeing the world as it is in itself” – the characters in Part I of Either/Or reveal this ideal as leading to practical absurdity. In contrast, Kierkegaard suggests that the ideal state consists in the achievement of equilibrium between the “spectator” and “actor” aspects of the human being. Kierkegaard’s proposal thus sets the stage for Niels Bohr’s “epistemological lesson of quantum theory.”
