6. Mathematics / A. Nature of Mathematics / 4. Using Numbers / a. Units

12273	Unit is the starting point of number [Aristotle]
	Full Idea: They say that the unit [monada] is the starting point of number (and the point the starting-point of a line).
	From: Aristotle (Topics [c.331 BCE], 108b30)
	A reaction: Yes, despite Frege's objections in the early part of the 'Grundlagen' (1884). I take arithmetic to be rooted in counting, despite all abstract definitions of number by Frege and Dedekind. Identity gives the unit, which is countable. See also Topics 141b9
