  Enframing, then, is the ordaining of destining that ushers in the modern technological clearing. But there is more to it than that. To see why, consider the following criticism of Heidegger's analysis, as we have unpacked it so far. Any suggestion that technological thinking has appeared for the first time along with our modern Western way of living would seem to be straightforwardly false. To put the point crudely, surely the ancient Greeks sometimes treated entities merely as instrumental means. But if that is right, and Heidegger would agree that it is, then how can it be that technological thinking defines the spirit of our age?
