Single Idea 17454

[filed under theme 6. Mathematics / C. Sources of Mathematics / 1. Mathematical Platonism / b. Against mathematical platonism ]

Full Idea

For a long time my daughter had no understanding of the question of how many numerals or numbers there are between 'one' and 'five'. I think she lacked the concept of numerals as objects which can themselves be counted.

Gist of Idea

Children can use numbers, without a concept of them as countable objects

Source

A Reaction

I can't make any sense of numbers actually being objects, though clearly treating all sorts of things as objects helps thinking (as in 'the victory is all that matters').


The 11 ideas from Richard G. Heck

In counting, numerals are used, not mentioned (as objects that have to correlated) [Heck]
We can understand cardinality without the idea of one-one correspondence [Heck]
Understanding 'just as many' needn't involve grasping one-one correspondence [Heck]
We can know 'just as many' without the concepts of equinumerosity or numbers [Heck]
Children can use numbers, without a concept of them as countable objects [Heck]
Is counting basically mindless, and independent of the cardinality involved? [Heck]
Counting is the assignment of successively larger cardinal numbers to collections [Heck]
The meaning of a number isn't just the numerals leading up to it [Heck]
A basic grasp of cardinal numbers needs an understanding of equinumerosity [Heck]
Equinumerosity is not the same concept as one-one correspondence [Heck]
Frege's Theorem explains why the numbers satisfy the Peano axioms [Heck]
