"Your theory of thrust and counter-thrust is imaginatively attractive. It reminds me of some pre-Socratics, notably Heraclitus, but I am not able to accept it as a sober theory of the universe; nor do I think that road to world peace can lie through any metaphysic. I do not think that, even if the conversion of mankind were possible given time, there is enough time for such an operation.... Nonetheless, I think that your book could do nothing but good and might induce some to adopt an anti-nuclear point of view who would be deaf to other ways of presenting the argument. I hope you will not think me discourteous if I say that I would rather you did not send me the ms as I am so overwhelmed with work that I do not know how I should find time to read it."
