Pause of Participation. On the Function of Artificial Presence.

Lambert Wiesing
, Friedrich Schiller University Jena

...

The common foundation of phenomenological image theories is the stance that the perception of images leads to a perception sui generis. In order to capture this distinction of image perception, two paths have traditionally been considered: either The Particular Object of Image Perception or The Unique Origin of Image Perception were described. The lecture wants to explore a third way within the phenomenology of the image by trying to determine the uniqueness of image perception through its peculiar, necessary effects on the perceiver of the image. The thesis is: The person perceiving an image is not a part of the image themself as an image object. Only in the case of image perception, there exists the relief of a pause of participation – the perception of something without the perceiving person being bodily involved in the actions perceived.

"Bild und Bildung": Seeing and knowing from the viewpoint of a neuroscientist

Ernst Pöppel
, Ludwig Maximilian University Munich

...

How is it possible that we see something? How is it possible that we have images in the mind? What happens when we create pictures?  Are these questions at all? They are for a brain scientist who questions the self-evident. Images we have in our mind, i.e. in our eyes or in our memory, have to be created like pictures in front of our eyes, i.e.  in the arts or in abstract representations. If one asks the very simple question what the visual stimuli physically speaking are that are processed by the retina in our eyes at any moment, one comes to the answer that it is only surfaces extended in visual space at some distance with different brightness and colours and edges with different orientations. There is nothing more, and this is the material out of which visual objects, i.e. images with meaning, are constructed. Taking an evolutionary perspective, images are re-constructed on the basis of neuronal mechanisms that have been developed over millions of years to create a match between the physical world around us („Realität“) and its representation in our mind („Wirklichkeit“). Interestingly, these mechanisms can also be studied in the arts; apparently, artists own an implicit knowledge about basic neurobiological principles.
