Aristotle famously distinguished the potential from the actual infinite, defending the former while rejecting the latter. Two millennia later, the subject was transformed by Cantor, who developed a deep and fruitful mathematical theory of actual infinities. In classical mathematics, the potential infinite has now almost entirely been eliminated in favor of the Cantorian “transfinite”. I argue that this is a mistake. I also discuss whether the infinite really exists and to what extent there are objective truths about it.
