Closer observations are made, as the result of which we are forced to conclude that the chair is “really” a swarm of electric charges whizzing about in empty space. … While the substantial chair is an abstraction easily made from the memories of innumerable sensations of sight and touch, the electric charge chair is a difficult and far-fetched abstraction from certain visual sensations so excessively rare that not one man in a million has ever been in the position to make it for himself. The overwhelming majority of us accept the electric-charge chair on authority, as good Catholics accept transubstantiation."
