Sam Moyn’s recent call for a renewed interest in a radical theory of law is timely and welcome. However, if LPE wants a social and legal theory adequate to its ambitions, we cannot turn to the insights of the earlier CLS movement to develop it. This is because CLS, in the relevant respects, did not have (much of) any theory at all.

Birds of a feather. Ships passing in the night. Sister species. How should we understand the relationship between LPE and the critical legal traditions?
