In 1960s France, there was a huge controversy among philosophers and others over so-called “humanism”. Rhetoric was excessive and overheated on both sides of the debate, promoting unhealthy and shallow polarization, but the topics dealt with were of great importance.
To begin to understand the various positions on this, it is necessary to realize that connotations of the word “humanism” in this context were quite different from what is usual in English. The third meaning listed in Google’s dictionary result, attributed to “some contemporary writers”, does at least have the virtue of expressing a position in philosophical anthropology, which is what was at issue in the French debate (in contrast both to Renaissance literary humanism and to explicitly nonreligious approaches to values).
Europe has an old tradition of self-identified Christian humanism. After the publication of Marx’s 1844 Manuscripts in the 1930s, non-Stalinist Marxists began talking about a Marxist humanism. In France after World War II, even the Stalinists wanted to claim the title of humanist. In his famous 1945 lecture “Existentialism is a Humanism”, the notoriously anti-religious and individualistic writer Jean-Paul Sartre surprised some people by placing his existentialism under a common “humanist” banner with Christians and Stalinists. What they all wanted to assert under the name of humanism was a particular view of what it is to be a human, emphasizing the centrality of free will and consciousness, and identifying humanness with being a Subject.
In the 1960s, these views were sharply criticized by people loosely associated with so-called “structuralism”, including Foucault, Althusser, and Lacan. The “structuralist” views denied strong claims of a unitary Subject of knowledge and action; rejected any unconditional free will; and took a deflationary approach to consciousness. Sartre and others launched vehement counter-attacks, and the debate degenerated into little better than name-calling on both sides.
In my youth, I was exposed first to views from the “humanist” side, and accepted them. Then I became aware of the “structuralist” alternative, and for a while became its zealous partisan.
In the Odyssey, Odysseus had to navigate between the twin hazards of Scylla and Charybdis. Since the millenium, I have emphasized a sort of middle way between “humanism” and “structuralism” — inspired especially by Aristotle and Brandom, and now with added support from Ricoeur.
Now I want to say, there is no Subject with a capital “S”, but I am highly interested in the details of subjectivity. There is no unconditional free will (and I even doubt the existence of a separate faculty of “will” distinct from reason and desire), but I am highly interested in voluntary action as discussed, e.g., by Aristotle and Ricoeur. I prefer to sharply distinguish apparently immediate “consciousness” from other-oriented, mediate, reflexive “self-consciousness”, putting most of the philosophical weight on the latter.
