L.I. Shestov and B. Pascal are extremely popular both in our country and in the West. The philosophical ideas of Shestov and Pascal often overlap despite the different epochs of the thinkers' lives. However, the philosophical ideas of Shestov and Pascal often overlap despite the fact that they lived in different eras. Shestov felt this connection only in the late period of his work, which was undoubtedly associated with the Pascalian renaissance in European thought. However, Shestov still managed to say his word about the life and thought of the French philosopher. The article provides brief information about the period of Shestov's life, when he began to seriously study the philosophy of Pascal. In addition, information is provided about the response in the Russian and French intellectual public that Shestov’s short work on Pascal “The Night of Gethsemane” received. The author's main attention is focused on the analysis of the views expressed by Shestov in his works about the French thinker. Based on the results of the study, it was established that in spiritual experience Pascal can be called the philosophical double of Shestov. In the experiment of Pascal, Shestov was primarily interested in the experience of the abyss, which was so close to the Russian thinker. However, other important aspects of Pascal’s philosophy: his concept of «the God of Abraham, Isaac, Jacob», and not «the God of philosophers and scientists»; the French thinker's interest in the individual, etc., were also extremely interesting to Shestov. Thus, many of B. Pascal’s philosophical and religious ideas were developed in the works of Shestov.
