The Concept of Lying includes: An exposé on "The Big Lie" that 'MM Murdered MM'! (That is, whether Marilyn Monroe murdered Marilyn Monroe).This work, firstly, examines "The Concept of Lying" in all its shady internal machinations: From the 'Big Lie' Theory of Adolf Hitler's Third Reich, to George Orwell's chilling spoof (written in 1948) of a futuristic New World Order based solely on the political propaganda of lies: Nineteen Eighty-Four. And, secondly, this work focuses on, arguably, one of the Biggest 'Big Lies' of our time (still swallowed hook, line, and sinker by the Mass and Social Media) that: MM Murdered MM)!On this 60th Anniversary of Miss Monroe's untimely death (and as based on the accumulation of updates depicting the exact events that occurred during her last weekend alive), we review this newer evidence that strongly suggests foul play. Although not definitive, the Author's conclusion may prove convincing (in light of this exposé).
