Single Idea 5525

[filed under theme 12. Knowledge Sources / A. A Priori Knowledge / 8. A Priori as Analytic ]

Full Idea

The concept of twelve is by no means already thought merely by my thinking of the unification of seven and five, and no matter how long I analyze my concept of such a possible sum I will still not find twelve in it.

Gist of Idea

No analysis of the sum of seven and five will in itself reveal twelve

Source

Immanuel Kant (Critique of Pure Reason [1781], B015)

Book Ref

A Reaction

I don't find this convincing. All sums can be revealed by analysing the relationships within the sequence of natural numbers.
