 The contemplation argument aims at showing the falsity of SI, by showing that its truth, together with the truth of AP and CP, triggers an infinite regress. If SI were true, then performing any action would require contemplating an infinite number of propositions of ever-increasing complexity. On the assumption that this cannot be done in a finite amount of time, the argument goes, accepting SI would lead to the clearly absurd conclusion that no agent could ever perform an action within a finite time (see Fantl 2011: 122).
