> From: Peter T. Daniels [mailto:grammatim@...]Don't act like a Luddite, Peter. I know you have heard of Plato. There are real-world objects, such as chairs, and there is also the concept of 'chair', which words in various languages such as "chair" or "chaise" or "เก้าอี้" denote. Just so there are instances of the letter A and also the concept of the letter A.
> What is "the concept of 'the letter A'"?
