Experiments may not reveal their full import at the time that they are performed. The scientists who perform them usually are testing a specific hypothesis and quite often have specific expectations limiting the possible inferences that can be drawn from the experiment. Nonetheless, as Hacking has said, experiments have lives of their own. Those lives do not end with the initial report of the results and consequences of the experiment. Going back and rethinking the consequences of the experiment in a new context, theoretical or empirical, has great merit as a strategy for investigation and for scientific problem analysis. I apply this analysis to the interplay between Fizeau's classic optical experiments and the building of special relativity. Einstein's understanding of the problems facing classical electrodynamics and optics, in part, was informed by Fizeau's 1851 experiments. However, between 1851 and 1905, Fizeau's experiments were duplicated and reinterpreted by a succession of scientists, including Hertz, Lorentz, and Michelson. Einstein's analysis of the consequences of the experiments is tied closely to this theoretical and experimental tradition. However, Einstein's own inferences from the experiments differ greatly from the inferences drawn by others in that tradition.

Recent work on the philosophy of Hermann Cohen (1848-1914), founder of the Marburg School of Neo-Kantianism, has appeared in three distinct circles in the English-speaking philosophical context. Cohen re-interpreted Kant's a priori to take scientific developments into account. Michael Friedman acknowledges that the later development of this view by Cohen's intellectual heir Ernst Cassirer influenced Friedman's work on the dynamic a priori, especially in the history and philosophy of science. Owing to Cohen's links to Franz Rosenzweig, scholars have begun to investigate Cohen's philosophy with reference to Derrida, Benjamin, Habermas, and Levinas and the philosophy of responsibility. And there is increasing interest in analyzing Cohen's influence on Deleuze and Badiou, particularly in the areas of ethics and aesthetics.
