 We will begin with some brief stage-setting: some historical background, some of the basics of decision theory, and some of the exegetical problems that the Pensées pose. Then we will follow the text to extract three main arguments. The bulk of the literature addresses the third of these arguments, as will the bulk of our discussion here. Some of the more technical and scholarly aspects of our discussion will be relegated to lengthy footnotes, to which there are links for the interested reader. All quotations are from §233 of Pensées (1910, Trotter translation), the ‘thought’ whose heading is “Infinite—nothing”.
