 Related to the distinction between meanings (2) and (3) is a distinction between metaphysical and mathematical meanings of infinity. This has been usefully employed in some of the most encompassing accounts of infinity, such as Moore (1990/2019; for another recent treatment that includes extensive discussion of the history of infinity see Zellini (2005)). Moore sees the metaphysical notion as bound up with the notions of ‘totality’, ‘absoluteness’ and ‘perfection’. While our entry is focused on the strict mathematical sense of ‘infinity’, one cannot cleanly separate the various meanings in the historical development of the subject, especially in the first stages. In addition, treating infinity as a ‘perfection’ in theology from the outset does not mirror the complexity of the historical development; for instance, we find traces in the 13th century of thinkers who attributed finiteness to God or in any case denied God’s infinity even when not explicitly stating the finiteness of God (see Coté 2002, 127–144).
