Principle of explosion

The principle of explosion is a logical principle which states that if we accept that a certain statement is true at the same time it is not true, then any other statement, no matter the truth value, can be proven. In other words, from a contradiction, any imaginable conclusion can be reached.

The Principle

The principle comes from an argument containing a proposition and its negation. By way of simplification and addition, anything can be proved deductively.

P1: A · ~A
P2: A (1, simplification)
P3: ~A (1, simplification)
P4: A v B (2, addition)
C: B, (3, 4 disjunctive syllogism)
