In many familiar objects everyone will recognize the human element. We conceive a given reality in this way or in that, to suit our purpose, and the reality passively submits to the conception…You can treat the adjoined figure [Figure of a ’Star of David’] as a star, as two big triangles crossing each other, as a hexagon with legs set up on its angles, as six equal triangles hanging together by their tips, etc. All these treatments are true treatments–the sensible THAT upon the paper resists no one of them. You can say of a line that it runs east, or you can say that it runs west, and the line per se accepts both descriptions without rebelling at the inconsistency.
