Well, I don't know about 'intuitively known mathematical truths'
(pretty sure they don't exist, certainly in <i>my</i> brain!), but
I'd agree, except for the bit about 'direct perception of an apple'.
There is no direct perception of anything. Only a flood of sensory
feature data that we have to make sense of (and actually, a large
part of it is discarded in the process). We don't perceive apples,
we construct them. And as a consequence, sometimes the things we
construct don't really exist, whether we realise it or not. Things
like unicorns, gods and 'physical qualities'.<br>
