Excerpts from Alva Nöe’s Strange Tools

"Tools are useful only against the background of our needs and capacities. Let’s return to the doorknob.

A designer of doorknobs makes a simple artifact, but does so with an eye to its mesh with this larger cognitive and anthropological framework." (99) More
