Fun:Torontological argument


 * 1) Definition 1: x is Toronto-like if and only if x has as essential properties those and only those properties which are positive
 * 2) Definition 2: A is an essence of x if and only if for every property B, x has B necessarily if and only if A entails B
 * 3) Definition 3: x necessarily exists if and only if every essence of x is necessarily exemplified
 * 4) Axiom 1: If a property is positive, then its negation is not positive
 * 5) Axiom 2: Any property entailed by—i.e., strictly implied by—a positive property is positive
 * 6) Axiom 3: The property of being Toronto-like is positive
 * 7) Axiom 4: If a property is positive, then it is necessarily positive
 * 8) Axiom 5: Necessary existence is positive
 * 9) Axiom 6: For any property P, if P is positive, then being necessarily P is positive
 * 10) Theorem 1: If a property is positive, then it is consistent, i.e., possibly exemplified
 * 11) Corollary 1: The property of being Toronto-like is consistent
 * 12) Theorem 2: If something is Toronto-like, then the property of being Toronto-like is an essence of that thing
 * 13) Theorem 3: Necessarily, the property of being Toronto-like is exemplified
