The first commandment of modern philosophy runs: Thou shalt emancipate thyself from all postulates. The postulate has been declared a deadly sin, and… - Lev Shestov

P. 28

The fundamental condition of the possibility of human knowledge consists in the fact that truth can be perceived by any normal man. Descartes had thus formulated it: God neither can nor wishes to cheat. Pascal, on the other hand, maintains that God both can be and wishes to be a cheat. Sometimes, to certain people, He reveals the truth; but He deliberately blinds the greater number of them in order that they should not perceive the truth. Who is right, Pascal or Descartes? p. 317

It is certain that Pascal never passed a day without suffering, and hardly knew what sleep was (Nietzsche's case was the same); it is also certain that Pascal, instead of feeling the solid earth beneath his feet as other men do, felt himself hanging unsupported over a precipice, and that had he given way to the "natural" law of gravity he would have fallen into a bottomless abyss. All his Pensées tell us this, and nothing but this. p. 291
