The mystical, irrational basis of Russian philosophy still remains one of its most attractive mysteries. However, this attribute, being mainly enigmatic and unusual for an analytical mind, appears to be an obstacle for its truly realistic understanding. The Russian mystical idea is often understood as some exotic poetry that has almost nothing to do with the real daily life. Nevertheless, the idea of irrationality and mysticism originates from the experience of individual and collective consciousness, i.e. from daily and quite this-worldly experience. In a certain sense, a human as a spiritual being is condemned to think irrationally. Otherwise his consciousness loses the ability to truly understand his being, the ability to create. In my work I wanted to underscore the topicality of the Russian 'mystical' world view and to point out its potency at the end of the second millennium. Actually, the development of the civilization has proven the necessity to 'rehabilitate' the ideas of irrationalism and aestheticism. The retreat from notorious 'Common sense logic' and thirst for different, i.e. nonutilitarian and nonpragmatic values are basic conditions for human survival and the last chance to preserve the Spirit.
