We know, in any case, that all efforts to think afresh are in fact directed at that obstacle: whether it is a matter of crossing the anthropological field, tearing ourselves free from it with the help of what it expresses, and rediscovering a purified ontology or a radical thought of being; or whether, rejecting not only psychologism and historicism, but all concrete forms of the anthropological prejudice, we attempt to question afresh the limits of thought, and to renew contact in this way with the project for a general critique of reason.
