Bazza Posted November 13, 2020 Report Share Posted November 13, 2020 Is 1 a number or an idea? Quote Link to comment Share on other sites More sharing options...
Cancer Posted November 13, 2020 Report Share Posted November 13, 2020 I have doubts whether, for 1 in particular, the concepts of "number" and "idea" are separable. We know that nonhuman animals can count objects up to 4 or 5 or so, and sometimes beyond, and there are some recent papers that indicate some animals even have a grasp of zero. Now those are different statements than saying they recognize 1 or 2 as being members of, e.g., the set of natural numbers; there are certainly human groups who have lacked that conceptual framework. The ideas of fractions and irrational numbers are extensions on those less-than-universally-available concepts. However, it is clear that the ideas of counting numbers have existed among humans for as long as any kind of enduring system of writing has existed; it is impressive how many samples of cuneiform, and how many of the translated cases of Linear B, involve what is basically accounting, keeping track of quantities of things.
