Single Idea 9965

[filed under theme 6. Mathematics / A. Nature of Mathematics / 3. Nature of Numbers / d. Natural numbers ]

Full Idea

It makes no sense to suppose there might be just one natural number, say seventeen.

Gist of Idea

There couldn't just be one number, such as 17

A Reaction

Hm. Not convinced. If numbers are essentially patterns, we might only have the number 'twelve', because we had built our religion around anything which exhibited that form (in any of its various arrangements). Nice point, though.


The 6 ideas with the same theme [the positive numbers used in counting]:

Cantor presented the totality of natural numbers as finite, not infinite [Cantor, by Mayberry]
The essence of natural numbers must reflect all the functions they perform [Sicha]
There couldn't just be one number, such as 17 [Jubien]
Only higher-order languages can specify that 0,1,2,... are all the natural numbers that there are [Shapiro]
Numbers are identified by their main properties and relations, involving the successor function [MacBride]
The number series is primitive, not the result of some set theoretic axioms [Almog]
