 The structuralism introduced into linguistics by Ferdinand de Saussure and Roman Jakobson, then adopted by other thinkers in the humanities and social sciences—most prominently by Claude Levi-Strauss in anthropology and by Jean Piaget in psychology (cf.  Levi-Strauss 1958 [1963], Piaget 1968 [1970], also Caws 1988)—does have ties to mathematical structuralism as well. However, they are looser than in the case of the philosophy of physics. In addition, the kind of psychological determinism often associated, or even identified, with structuralism in the humanities and social sciences (and criticized in post-structuralism) has no analogue on the side of mathematics (or physics).  Still, these connections are not totally uninteresting (starting with contacts between Levi-Strauss and mathematicians in the Bourbaki group, cf. Dosse 1991–92 [1997]). Hence they might be worth exploring further too, in this case not so much to derive benefits for the philosophy of mathematics, but to understand the history of structuralism in human thought more fully.
