Universal criterion of truth

The cornerstone of the theory of cognition of any philosophical system or doctrine is the question of truth. On the basis of the analysis of Lenin''s work Materialism and Empiriocriticism it is shown that the criterion of truth or truth of the forms of developing reality is not practice as is erroneously considered in this time but the pithiness of these forms; practice is a method or procedure for assessing the completeness of the pithiness of the forms of reality. In addition practice is only a special case of a more developed technology of establishing truth - interpretation. The criterion of truth put forward in this paper allows quantitatively assessing the pithiness and significance of the forms of reality which in turn makes it possible to rank the forms and on this basis more consciously outline the directions of prospective research. In the same connection it is noted that there are no two or more equally meaningful truths (ideas ideas ideas ideas statements theories concepts models opinions points of view etc.). At any given moment of development the truth in this sense is always the same.
