In his recent post about the LPE Movement’s reticence toward legal theory, Sam Moyn speculates that this aversion may be born of a noble yet misguided deference towards grassroots social movements. Deference, however, does not capture the dynamic relationship between critical legal theory and radical political practice. One does not precede the other or take priority. Instead, from W.E.B. Du Bois to Michel Foucault to Angela Davis, our most important critical thinkers have always engaged in a productive back-and-forth, in which theory and practice constantly challenge, check, and transform each other.
