today I present a video conference about the problem of the Image of the Invisible by the important french philosopher Olivier Boulnois (*1961) . Boulnois has published several important books about the birth of the so called modern philosophy and challenged the view that Descartes is its father (cf. his work Être et représentation. Une généalogie de la métaphysique moderne à l'époque de Duns Scot, Paris, PUF 1999. More recently he published a book about the genesis of our idea of the image in his work Au-delà de l'image, Paris, Seuil, 2008.
