An axiom that is deemed to be true is not by definition or otherwise *thereby* true. If someone comes along and proposes some few axioms and shows off how impressive that so few can generate so much, it is still an open question whether the axioms are true or false or perhaps something else.

What an intriguing suggestion! Yes. Put a pig on a small enough asteroid that has low gravity and it could fly! (And you wouldn't need a Martian help for that). Trivial fact perhaps but nothing intriguing. Another example, keep the meaning of "It's raining" the same, but change the model at will to change the truth of it. It's all just a game of the mind. >> The point is mathematics is still just a game, even though it might be a >> useful one by no coincidence. > > The point is that it is not always just a game then. Let me repeat: Mathematics is a game of the mind.

You can repeat it as much as you like. It does not make it true and it still needs an argument. Your above misunderstanding should surely make you pause before being quite so confident as to simply repeat it again without further supporting explanation and argument. -- dorayme |
