1. We MAY possibly have a sound mathematical argument for
 the Poincaré conjecture.
Actually I believe we have already such an argument (actually a proof) even I'm
not in a position to check details of Perelman's proof. But I have confidence
to experts who cheked it.

2. We  MAY NOT possibly have a sound mathematical argument for
the negation of the Poincaré conjecture. This is because it is no longer a
conjecture but a theorem.

3. Perelman's proof of the Poincaré conjecture IS  a
mathematical proof proper, and DOES NOT involve some further
non-mathematical assumptions.

4. Perelman's proof IS NOT a mixture of mathematical reasoning
and philosophical speculation.
Otherwise the mathematical community would not come to the consensus about it
like it does not come to the consensus about foundations: unlike mathematical
proofs philosophical speculations never result into a consensus.
