Iain Thomson's critique is persuasive on several points but not on the majo
r issue, the relation of the ontological to the ontic in Heidegger's philos
ophy of technology. This reply attempts to show that these two dimensions o
f Heidegger's theory are closely related, at least in the technological dom
ain, and not separate, as Thomson affirms. It is argued that Heidegger's ev
aluations of particular technologies, the flaws of which Thomson concedes,
proceed from a flawed ontological conception.
