Blaise Pascal's famous Pens es (Thoughts) is, in reality, a collection of notes he made for a book he never wrote. Many of the thoughts are fragmentary in nature, and the sectionalising and numbering was devised by a later editor. Yet they contain the key ideas of his religious philosophy, including his famous wager, as well as many other insights and ideas such as his celebrated comment on Cleopatra's nose. This is a new edition (not a scan) of the W. F. Trotter translation of 1908, with an introduction by T. S. Eliot.
