P. 304, l. 9. M. le M. Le Maistre, Antoine, 1608-1658. The allusion is to Les Plaidoyers et Harangues de M. le Maistre, Paris, 1657. On the first page of Plaidoyer VI., Pour un fils mis en religion par force, we find "Dieu qui répand des aveuglements et des ténèbres sur les passions illégitimes," and Pascal probably refers to this passage as one in which the word répandre could not be replaced by verser.
