Bridging the "Is"-"Ought" Gap: How to Derive Morality from Facts by Dr. Harry Binswanger   Can morality be proved? Can an objective, scientific system of moral values be rationally derived from the facts of reality? Most philosophers accept David Hume's argument that this is impossible, that an unbridgeable gulf separates values from facts. Dr. Binswanger first refutes Hume's argument for the fact-value dichotomy, and then offers a step-by-step account of Ayn Rand's derivation of a moral code based on one's own life as an ultimate value.
