The Chair Is Only a Chair if I Behave to It

How much of our world is created by our consciousness and how much of the world creates our consciousness? Maybe it's a circular, iterative process, maybe the answer is both. So there's a repetitive aspect where the machining production of these goods is something that is starkly present to me... But at the same time, a chair is only a chair if I behave toward it as though it was a chair. And in that sense, my actions, my gestures that generate the world.
