On the Information as on the Utmost Fundamental Concept

In this report the concept of the Information as Utmost fundamental essence is presented. It is shown that there are the strict logical grounds to such a conclusion, so all that exists, including what we call "the Matter", "Material World", "Universe" "Consciousness", etc., - are the realisations / "modes of the existence" of the Information, when the Information itself is a specific infinite set having unique properties. The presented approach lets to understand a number of fundamental philosophical and physical problems when an investigating of the set "Information" by using some ready instruments, such as the set and language theories, synergetics, cybernetics, etc., will enable, with rather great probability, to obtain new data about the Nature.
