Berdyaev has been categorized as a Christian existentialist and a mystical philosopher. He never avoided the label of "mystic" since he felt it was the mystics of the world who came closest to understanding the role of spirit. Many of the philosophers he quoted were mystics - Meister Eckhart, Angelus Silesius and especially Jacob Boehme. The influence of Dostoevsky was central to his thought. Nevertheless, Berdyaev is not a naively irrational thinker; he brings an enormous fund of philosophical knowledge combined with the profundity of his own thought to support his view of existence. There are no dogmas in his writings to offend one's intellectual conscience.
