Calling

In primitive man as in all human beings the desire to enter into contact wi!h the sacred is counteracted by the fear of being obliged to renounce the simple human condition and become a more or less pliant instrument for some manifestation of the sacred (gods, spirits, ancestors, etc.).

—Mircea Eliade, Shamanism

This is why every authentic prophet is a reluctant one.

Caravaggio, The Calling of St. Matthew, 1599-1600.

Of this kind of "interpellation" Althusser knows nothing.
