I am an invisible man. No, I am not a spook like those who haunted Edgar Allen Poe; nor am I one of your Hollywood-movie ectoplasms.I am a man of substance, of flesh and bone, fibre and liquidsöand Imight even be said to possess a mind.I am invisible, understand, simply because people refuse to see me† When they approach me they see only my surroundings, themselves, or figments of their imaginationöindeed, everything and anything except me.

Every individual†intends only his own gain, and he is in this as in many other cases led by an invisible hand to promote an end which was no part of his intention† By pursuing his own interest he frequently promotes that of the society more effectually than when he really intends to promote it. I have never known much good done by those who affected to trade for the publick good.
