### Ideas of Richard G. Heck, by Text

#### [American, fl. 2000, At Harvard University.]

 2000 Cardinality, Counting and Equinumerosity
 3 p.194 17448 In counting, numerals are used, not mentioned (as objects that have to correlated)
 3 p.196 17449 We can understand cardinality without the idea of one-one correspondence
 4 p.198 17450 Understanding 'just as many' needn't involve grasping one-one correspondence
 4 p.199 17451 We can know 'just as many' without the concepts of equinumerosity or numbers
 5 p.200 17453 The meaning of a number isn't just the numerals leading up to it
 5 p.201 17454 Children can use numbers, without a concept of them as countable objects
 5 p.202 17455 Is counting basically mindless, and independent of the cardinality involved?
 5 p.202 17456 Counting is the assignment of successively larger cardinal numbers to collections
 6 p.202 17457 A basic grasp of cardinal numbers needs an understanding of equinumerosity
 6 p.203 17458 Equinumerosity is not the same concept as one-one correspondence
 6 p.204 17459 Frege's Theorem explains why the numbers satisfy the Peano axioms
