Are we able to wrap our mind around infinity?
Infinity. It’s a puzzling concept. Is it real, or a mathematical fiction?
Aristotle believed infinity could only be potential, never actual. To speak of an actual infinity, he argued, is to fall into logical contradiction: “The infinite turns out to be the contrary of what it is said to be,” Aristotle wrote in the Physics. “It is not what has nothing outside it that is infinite, but what always has something outside it.”
