"The philosophies of one age have become the absurdities of the next, and the foolishness of yesterday has become the wisdom of tomorrow..."

by Sir William Osler

Sorcerers and charlatans have always found success in marketing their wares since there was (and is) disagreement regarding what is efficacious.
