Almost nobody does, at least today. Some offtopic. The reverse side of the dollar bill depicts a small pyramid with an eye on it. This symbol is a pretty clever summary of our civilization. The eye means the human mind that connects a small upward facing triangle at the top - the spirit, with a heavy structure at the bottom - the matter. The upper triangle is small because today people barely recognize its existence. The mind tries to figure out which side it belongs too and often it gives up and identifies oneself with the matter. The "purpose" from the comment above is the pinnacle of this thinking: the mind decides that "since I really belong to this two legged biomachine, my purpose must be same with that machine's".
