Bruno:
1. And if someones (1-?)personal "taste" does not
accept the (and only) math ways?
Can I say: I am right and the rest of the world is
wrong?
2.You mention Occam, I was in love with him for many
years. Now: I consider his razor-cut "essence" as a
simulacron, a limited model of the content I just want
to consider (talk abouit), keaving out any further
ramifications as 'only obscuring the clear view'.
Do we want to "see clearly" the part we want to see
clearly? Are "all possible cases" the selection we
want (or can) include?
