“People have the need to put their hands on tools and to make things. We need this in order to feel whole.” As Rogowski explains: “Long ago we learned to think by using our hands, not the other way around.” As our species evolved, in other words, we did so as beings that experience and manipulate the world around us. We are orders of magnitude better at doing this than any other animal, and this is true due to complex structures that evolved in our brains to support this ability.
