Abstract

Aristotle's distinction between the practical life and the contemplative life has been of central importance in fixing the sort of justification that is required for engineering activity. As practical it must be justified by its products, while intellect's activity claims intrinsic worth. Most philosophers of technology accept this model of justification. However, engineering is not essentially practical in the relevant sense. To claim that it is overlooks a distinction between "structuring ends" and "products" which when made allows engineering to lay claim to the same sort of value as intellectual activity. The final conclusion is that both have intrinsic worth but that does not free either from the obligation to look to their consequences.
