Summary
This quote refers to the concept of mathematical infinities. It suggests that not all infinities are equal in size, implying that there are varying degrees of infinity. In mathematics, different sets of numbers can have different cardinalities, or sizes of infinity. For example, the set of natural numbers is considered "smaller" than the set of real numbers, even though both are infinite. This quote highlights the fascinating and counterintuitive nature of infinity in mathematics, where some infinite quantities can be larger or more encompassing than others.
