Holding Plato accountable for scientific knowledge that did not remotely exist during his time is a little unfair, don't you think? Plato intuited deep understandings about reality, conveyed (as they must be) by metaphors, which have only been confirmed by modern physics. But they also harmonize with the intuitive insights of the great Buddhist sages as well. This is because that is. And in this case, "that" can be seen as the intelligible forms of reality, and "this" as the sensible, time-bound, manifestations thereof.
