Human beings own three ways of investigating Nature, in a tempting to achieve only a spark of truth: Science, Art, “Mystical Perception of the Nature”. Science observes, analyzes, deduces, formalizes and constructs theories and algorithms, often transferring them to the technology that is able to adapt the environment to our material needs. Art looks at Nature and, via sentiment and imagination, recreates it, changes it, overcomes it, proposing it anew, merging it into a dimension that goes farther than reality, often farther than reason and plausibility, into the kingdom of metaphysics where ideal models are placed as foundations for the fantastic reconstruction of Nature, so acquiring self-contained life and becoming a fundamental part of Nature herself. Mystical Perception is, among these threeways, the most primitive, typical of saints and ascetics, of authentic artists, of primitives and poets. Mystical Perception makes the Universe seem like a unique consistent organism, totally accessible to our mind. In the intensity of Mystical Perception our mind rises to unknown dimensions, which often bring human beings to reach out of themselves, isolating and cutting bonds with others and putting them in perfect, direct and solitary connection with the most hidden essence of all things and of all the universe. These three possibilities in understanding Nature integrate and mature each other and often interchange and fade into the other. So there's a beauty - not merely formal – of Science, of physics and mathematics, as exists even an Art's science and a matematics of music; and Art itself, as Science, has a mystical feature, and the mystic is often an artist too, because he feels and senses where others remain unconcerned, in the same manner the scientist who suddenly sees a new way that opens the doors of a new theory… Man, in his remaining evolutive process, will succeed to be more human as he will be able, at the same time, to be a scientist, artist and saint; namely as he will be able to receive and awaken unto himself, with harmony and honesty, these three fundamental ways of wisdom, in the attempt to understand the elusive meaning of himself and of the universe. For this to happen , teaching the beauty and respect for life is paramount.
