I concur with Budd's comment, that learning every possible physical
fact is simply not credible.

However, that newly acquired knowledge was acquaintance knowledge
rather than propositional knowledge.  So this does not contradict the
assumption about having previously learned every possible physical  fact
about the situation.  I'm not at all convinced that you can  infer
property dualism from acquiring acquaintance knowledge.
