"You should be spreading the good word. You should be etching..." — Douglas Coupland quote meaning

You should be spreading the good word. You should be etching the good word onto the glass scanning beds of library photocopiers. You should be scraping the truth onto old auto parts and throwing them off bridges so that people digging in the mud in a million years will question the world, too. You should be carving eyeballs into tire treads and onto shoe soles so that your every trail speaks of thinking and faith and belief. You should be designing molecules that crystallize into poems of devotion. You should be making bar codes that print out truth, not lies. You shouldn't even throw away a piece of litter unless it has the truth stamped on it--a demand for people to reach a finer place!
