The title concepts of criticism, crisis, and wisdom are taken from the paradigm of Kantian philosophy and are characterised in the development given by the contemporary philosopher Odo Marquard. In this connection I present the relationship between wisdom and thinking in the Enlightenment usage. The call for philosophy to be self-understanding in the sense of the Enlightenment Bildung and the autonomy of science and wisdom sounds particularly strong here. I conclude that philosophy becomes stupidity when it turns into a field (...) that—because of some kind of philosophical fundamentalism—would like to become this one-sided attitude towards reality that eliminates and replaces other attitudes.
