Ah, I've got it. It's easy for me to be in favour of thinking, because I have had and still do intermittently have ease of thought. But I now see that it's contingent and not under my power, and I see that if I hadn't had it at school my life would have been very different. It's not clear to me that if I had never had it I would be very sympathetic to this manifesto, and it's not clear to me that the people this manifesto is targeted at are necessarily going to have ease of thought. (That's particularly, but not exclusively, ease of geekoid mathmo-technical thought.)

For an extreme example, I know a contemporary of Kathy's who had a brain haemorrhage at birth in the maths-area, and now has great difficulty with plus and minus one, while Kathy is loving everything numerical. It seems extraordinary to me that something as fundamental as number should be so localised and biological and vulnerable, but it clearly is.
