Purрose of the рaрer is to emphasize affinity and succession in the aррroaches of Descartes and Kierkegaard to the interpretation of key factors of their philosophical search. It could be implemented through understanding such viewpoints of both thinkers as a) appropriate reasons for human existence; b) possible factors for human freedom as a condition of self-actualization; c) original approach to prove the existence of God. Theoretical basis. The use of phenomenology and hermeneutics enable us to comprehend the key philosopher’s ideas (...) as the manifestation of their personalities. Originality. The author believes that it is quite right to refer to the philosophy of the early modern period as a form of its demand fulfillment for human development. An essential prerequisite for revealing the toрic of the article is a focus on the latest investigations of Descartes’ philosophy, which demonstrate the anthropological significance. Since Kierkegaard’s viewpoint was developed through depersonalized understanding of philosophy, related motives of their thoughts are expressed by emphasizing their personal motives of philosophizing. This affinity is reflected firstly, in distancing from depersonalized and dehumanized world view; secondly, in religion-oriented search and proof of God’s existence based on human nature. Conclusions. Due to the modern state of historical and philosophical science, it is possible to argue that Descartes and Kierkegaard had content-related philosophizing motives, which are close to current search. Interpreting Descartes’ anthropological project by Kierkegaard, the author states the accepted determining influence of Hegel’s philosophy interpretation in general and his interpretation of Descartes, in particular. This argument allows to understand Kierkegaard’s search as Hegel’s deconstruction, because further uncritical retention and reproduction of his viewpoints are evaluated as a threat to fulfill human spiritual calling. A common and important thing in the views of both thinkers is their strong interest in individual and personal aspects of human nature as a constituent factor of God’s existence. (shrink)
