This course aims to bridge and to enlarge pillars of (bio)semiotics – Saussure, Peirce and Uexkull – in light of phenomenology and current neuropsychology. It explores concepts and exemplary models that serve to prompt creative ideas for our trade of perceiving, interpreting and inventing clues and evidence. By way of examining selected original writings, we expect not only to sharpen our skill of perceiving art phenomena, but also to deepen our understanding of the power of images and memories in working out various kinds of art. This course culminates in a re-visitation of certain art historians’ perspectives that already suggest the importance of strategy formation and certain cognitive benefits we may gain from reinventing clues, monuments and documents.
