Greenie gave a half-hour interview to CBC Radio One this morning.
In the interview and the book, he discussed an amusing encounter with Ayn Rand in his youth. Of course, being a much greener Greenie and not a scientist, he had no way of knowing that she challenged him with the classic exercise (taken out of context I might add) done by Descartes centuries earlier:

The Cartesian Method
In Part 4 of the Discourse, Descartes outlines his method of doubt, leading to the famous conclusion ‘I think, therefore I am’ (cogito ergo sum). There are three points to note about this: first, ‘cogito ergo sum’ is not a syllogism (‘Whatever thinks, exists.’ ‘I think.’ ‘Therefore I exist.’), but a simple intuition of the mind. Second, the doubts he proposes are not a recommendation of skepticism; they are a preliminary technique for arriving at the basis for certainty. And third, though cogito ergo sum is Descartes’ best-known philosophical maxim, it does not contain the main substance of his contribution to scientific thinking. This is to be found earlier, in Part 2 of the Discourse, where Descartes gives his four rules, or precepts, for systematic thinking in the area of the sciences. — Tom Griffith, Essential Thinkers: Descartes

Again, if there is one book you read this year, make it The Age of Turbulence.

Greenie was also interviewed for NPR on September 18, and September 19.
