From an ontological point of view, computers – similar to Heidegger’s notion on Being – “are” not at all. Today, they are required to deter- mine any kind of being. They, therefore, precede any kind of being. Computers “are” not, they exist as an invisible given, which penetrates everything. Foremost, computers are nothing specific. As a universal medium, they are similar to that which Aristotle called the diaphanes, the “transparent” – an undetermined “in-between,” metaxu, which has to be formless in exactitude to take on any form and to transport all possible impressions. The significance of the computer also correlates to an image of the Stoics, the apeiron, ”the in-finite,” which, being primal matter par excellence, includes the possibility of any other matter, and which, exactly because of that, has no proper qualities itself. It is therefore no accident that transparency is the ethos of our time.
