everyone, please welcome jason kuznicki. [applauding] >> thank you. i would like toçó start by sayig that my own training is in intellectual history, although it is not specifically in the history of science. i personally am not a scientist. some some of the material you just heard, i'm actually a little bit afraid to comment about, in particular global warming because it is not a subject i really do much work on unfortunately. but i would like to say a few things about the book the science of liberty and about its thesis, about what i did it is time to do and why i think that it is a very important and interesting but. i would also like to offer a few criticisms of the book because it really would not be fair of me to give up here and have nothing but praise. it would make the discussion kind of boring if that were the case. so most of us who have heard of timothy ferris think of him as primarily a science writer. i know when i was in high schoolbag i was very interestedn it. i would probably be a little bit embarrassed to see my notes in that book r
