[MD] Platt's Individual Level

[Case]

Steve, 
I think the best argument against my assertion is the Platonic one 
whereby all pure ideas exist in a Platonic realm outside the cave, and 
we deal only in the shadows. Smarter individuals than I, like Roger 
Penrose, believe this to be the case. The more I think about it, the 
more Quality in its pure form exists in the Platonic realm, and we are 
the beneficiaries of its shadows. Through beauty we get a glimpse of 
Quality's light.

But I could be wrong.

[Case]
It sounds as though Penrose is weighing in on the debate over whether
mathematics are invented or discovered. I doubt that he is making Platonic
assertions about whether or not there is an ideal chair. Since Pirsig
defines Quality as undefined it is hard to see how it could be a Platonic
ideal.
