“Reality is that which, when you stop believing in it, doesn't go away.” This profound insight comes not from a philosopher but from the celebrated science fiction author, psychotropic drug enthusiast and mystic, Philip K Dick. There is an ultimate primordial difference between reality and falsehood, between truth and counterfeit. Falsehoods, lies, counterfeits, deceptions are invented by human minds.
