This is not about charity, it's about justice... The war against terror is bound up in the war against poverty - I didn't say that, Colin Powell said that . . .

Most people...are put off science because maths is the gateway and they can't handle it. What we should be teaching is operational maths because, in general, the maths we need to carry out science is pretty straightforward.

This new meta-system is very much in favor of the self, but a self that is based on a proper sense of dignity, not on an inflated ego. A person who dare not admit he is wrong inflates his ego but weakens his self.
