In July, 2021, the European Graduate School Saas-Fee, Switzerland, invited Gerhard Hofbauer to give a lecture at the sommerschool. The main topic was the anchoring of polyaesthetics in the theory of "Expressive Arts" according to Paolo Knill. Similarities in the development of both concepts were explored, examples of polyaesthetic projects were presented and discussed shortly. Participants from all continents followed interactively.
