Behavioral Science is not for Sissies. My review of Steven Pinker’s The Blank Slate (the above quote from p.121). I believe this will be an important work in my research into understanding knowledge, so much so that I felt the need to post a review even though I’m only half-way through. You get some flavour of the breadth from Pinker’s own quote from Kant’s Critique of Practical Reason [Quote] Two things fill the mind with ever new and increasing admiration and awe; the starry heavens above and the moral law within.
