Infinity: Infinity, the concept of something that is unlimited, endless, without bound. The common symbol for infinity, â, was invented by the English mathematician John Wallis in 1657. Three main types of infinity may be distinguished: the mathematical, the physical, and the metaphysical.
Thomas Aquinas, the Christian theologian and philosopher, used the fact that there was not a number to represent infinity as an argument against the existence of the actual infinite. In Summa theologia, written in the 13th Century, Thomas Aquinas wrote:-. The existence of an actual infinite multitude is impossible.
