PHASE ONE: The Power of Words
 

If it be true that all knowledge lies only in the perception of the agreement or disagreement of our own ideas, the visions of an enthusiast and the reasoning of a sober man will be equally certain. It is no matter how things are: so a man observes but the agreement of his own imagination, and talk conformably, it is all truth, all certainty.


John Locke, “An Essay Concerning Human Understanding”
