Maybe soon they will start teaching two versions of mathematics, one where 2+2 = 4 and one where 2 + 2 = 5 and let the pupils choose | |

If you turn that into a lesson on showing how mathematical principles are derived from axioms, and how axioms are rooted in empirics, I think it would be a very valuable lesson, not just in mathematics but also in epistemology.

On the other hand, if you think its better to teach that, on authority 2+2=4, how then are kids going to deal with somebody else telling them on authority that 2+2=5 if they haven't learnt anything about reasoning?
