A poem by Tschuang-tse is added. I will change it a little:
… on the way back home (the philosopher king) lost his "no-colour" (nichtfarben, colourless) pearl. He sends out science to look fort he pearl. (Science does not have a concept of „no-colour“ and can not bring the pearl.) He sends out critique. (Critique sees too many "Nos" & finds not.) He sends out logic. (Logic knows no colours and can´t bring the no-colour/colourless pearl.) Then (the philosopher king) asks Nothing (das Nichts) and Nothing had the night-coloured (nachtfarbene) pearl.
(Text in brackets is my interpretation) – oh yes, >nichtfarben< ought to read >nachtfarben< and the switch > from a to i < was following no Intention. It was unintentional … absichtslos.
Philosophical practice takes place where the guest of a practitioner finds the way out of her/his problem themself. ( p. 8 )
