How would Veeky Forums define 'one'? Without using words such as 'single', 'unit' or any other numbers

Aristotle pls go

Half of two

0!=1

1 := S(0) : 0 is the empty set,
S(x) := x U {x}

So there is one set containing one set and you use this to define "one"?

floor (log10 (floor (log10 (x))))

>Which naturals
Naturals as in counting numbers.
>naturals without zero
Try counting zero objects.

Unity

the factor shared by all prime numbers
