  There is a complementary reason for urging caution about reading Pascal as a philosopher. He wrote much but published little, none of which was philosophy in the sense in which that term is used today [see section 6]. Apart from his brief essays on the vacuum and the Provincial Letters, all his writings were edited and amended posthumously by collaborators who were still involved in the theological controversies that had dominated Pascal's later life. For example, he seems to have contributed to an early version of the Port-Royal Logic (Arnauld and Nicole, 1993) that was subsequently published in 1662; and the Entretien avec M. de Sacy was composed many years after his death, based on the recollections of an editor. Thus philosophical opinions that were attributed to him in various writings that he left only in draft versions should be read with caution, because they were published posthumously by partisan proponents of Jansenism rather than their original author.  His apparent disenchantment with philosophical studies is reflected in Fragment 77 of the Pensées: “we do not believe the whole of philosophy to be worth one hour's effort” (II, 566). This may also testify to the extreme ill-health and loneliness he experienced in his final years, when he reported that he could find consolation for his misery only in religion.
