modus ponens
Modus ponens is the creed that chanting “If P then Q” summons Q from the spell of P alone. It is a hotbed where the seeds of words sown in the desert of thought sprout the illusion of conveniently chosen conclusions. It serves as a runaway device, rendering its adherents blind to anything but Q, as they abandon the maze of debate. Here begins the quiet theatre of logic, devoid of the audience called truth.
