A theory? Yes. No need to be afraid of the word, which has been set aside of late, leaving space to be filled up with a mushy mass, a crazy mix, of bits and pieces. Without theory, thought goes round in circles, commentaries and opinions abound, the mind gets clogged up by imagination and fantasy, every gesture gets lost in the big showbiz, details pile up without perspective, life gets stifled in a daily routine that is more and more opaque and senseless.
But, to be valid at all, theory must be based on fundamental thought, must be connected to substantial practice, must remain open (which doesn’t mean open to anything).
