A bit presumptuous
In continuing with my reading biographies of the founding fathers, I picked up this one about Thomas Jefferson. It's not a straight biography in the sense that it goes through his life chronologically, but rather the author spends a lot of time examining the character of Jefferson. I think he presumed to know a lot more than Jefferson's writings left; in other words, he makes some real leaps in logic that I'm not sure I buy. It's all just a little presumptuous.
