This book was really quite a disappointment. Frankly, Pascal is dull. Apart from a few well-known purple passages, the Pensées (pp. 90-209) mostly consist of a collection of disjointed, fragmentary, premodern ethical musings.
What Appelbaum presents here is a selection - so this is not a complete set, and certainly it is not a critical edition.
The rest of the book contains four of the nineteen Provincial Letters (1, 7, 9, 11). These are Jansenist polemics. Dullsville... I just skimmed them. Imagine... a writer that makes the Jesuits look like the 'dangerous hipster set'.... and that gives you some idea of what you're dealing with here with ole' Blaise....
Appelbaum himself -- well, I discovered from his dual-edition of Rimbaud that he is an untrustworthy guide as a translator (see my updates or comments ad loc.). The strange thing is that old Stanley seems actually to have an expert's familiarity with Jansenist polemics, and gets really excited -- tossing in a lot of '!!' at the strangest places.... I suspect that he didn't get that itch from his babushka... but, hey... whatever moves your (drunken) boat!
