Poiesis is making, techne is knowing how to do things, including making. When the making in question is of an explicitly material nature, as in sculpture, architecture, carpentry, etc., the role of techne is relatively unproblematic. It involves a knowledge of materials, tools, and, physical techniques (hence the word techniques). (This is the stating-the-obvious part, so please bear with me.) The techne of the builder, the craftsperson, the designer, is measurable and finite, at least at a certain basic level that defines minimal competence.Discussion over at the lime-tree.
