This work has been proved by the example of the dramaLife is the dream, of writer Pedro Calderon de la Barca, that philosophy is largely presented in literature. The whole problem was addressed in the way that the topic of skepticism was discussed in the beginning of the work, its divisions were presented, of which more elaborated it was in antique and modern skepticism. Concerning skepticism, Barry Stroud's views on the external world and Rene Descartes were elaborated, and his arguments for skepticism were presented: the argument of pertinent perception, the argument of the evil demon, and the argument of dream. In the central part of the work, all these arguments are supported by the situations between the characters in the aforementioned drama. In addition, some philosophical questions, such as the determinism with which the question of free will and the question of personal identity are concerned, are also considered in the central part of the work. And these problems have been found in situations and characters from the aforementioned drama. In the final part of the paper, the philosopher Lamarque and Olsen's philosophical opinions were expressed, and the whole work was concluded with my own opinion in opposition to Lamarque and Olsen.
