Abstract
From recent philosophy of technology emerges the need for an ethical assessment of the ordinary use of technological
devices, in particular telephones, computers, and all kind of digital artifacts. The usual method of
academic ethics, which is a top-down deduction starting with metaethics and ending in applied ethics, appears
to be largely unproductive for this task. It provides “ideal” advice, that is to say formal and often sterile. As
in the opposition between “ordinary language” philosophy and “ideal language” philosophy, the ordinary
requires attention and an ethical investigation of the complex and pervasive use of everyday technological
devices. Some examples indicate how a bottom-up reinvention of the ethics of technology can help in numerous
techno-philosophical predicaments, including ethical sustainability.
