Science, philosophy and the a priori

This is an introductory essay to the symposium on Michael Friedman’s Dynamics of Reason. It provides a summary description of the symposium and its rationale; an introduction to Michael Friedman’s views on the a priori and to what it refers to as ‘developmental Kantianism’; a summary of the content of each of the four contributed papers in the symposium; and a philosophical analysis of the symposium as a whole in relation with developmental Kantianism.
