The collection includes two of the most famous works of Nikolai Berdyaev - an outstanding Russian thinker, a follower of Kant, Nietzsche, Schopenhauer, one of the brightest representatives of idealistic philosophy. "Man," "personality," "individual," "freedom," "God" - the most important categories of Berdyaev's philosophy. Paul and Lyubov Berdyaev considered the main world issues and devoted the work "Metaphysics of Gender and Love" to them. Sensuality, like the conservative push to curb gender, has nothing to do with Love. The institution of marriage strengthens only generic love, and it is metaphysically lower than personal love. The highest form of love is not for procreation. Romeo and Juliet, Dante and Beatrice did not continue the birth. The highest manifestation of love is the renunciation of the worldly, mystical secret of two.
