The Platonic World. Real or a human construct?

[oldman]

Your parting line suggests the reason why you don't accept the notion of mathematical reality outside of the physical domain - it seems that for you anything real must be physical?

Yes -- I'm afraid this is true. I'm a regular heathen. It is nevertheless also true that a great deal of what is enjoyable and stimulating is not physical; music, mathematics and this forum are examples. It seems that the very effective faculties of communication that evolution has endowed us with must be exercised! Thanks for your comments.
