Therefore those correct solutions, which the person finds, is difficult to call as the ultimate truth, they are rather the result of his experience, experience of prior generations, its own ingenuity, its ability to produce some general, to develop new theories, to deduce regularities on the basis of which he can produce new experiments, drawing other conclusions, and etc. But all this doesn't give exhaustive and final knowledge of a subject.
Indeed, this definition can reflect only aspiration of human intelligence to cognition of things. The intelligence of the person is feeble, his life is short, and the real world is infinitely various. Some established patterns during cognition, flow of life are changed by others; new relationships, communications emerge.
At this the world of the human relations is more complex and unstable, than the physical world. All achievements of human thought don't lead to elimination of dissociation of certain individuals and different peoples.
The nature shows the force periodically, incomparable with human, easily breaking any human construction, as and the person, despite a present technical equipment of mankind.
Therefore the doubt appears in many minds: are there any comprehensive, full or absolute truths generally, time nothing can make the person happy, his life the infinite and cloudless and, at the same time, meaningful?
And indeed, we can operate by concept of absolute truth only concerning such banal statements as Volga flows into the Caspian Sea, and even then – in frames of the current life, when there are still seas and life itself.
The deepening of scientists in the microcosm, in space exploration doesn't explain the appearance of the live in this world, appearance of self-consciousness in the humanoid, more precisely, the appearance of the being which can understand itself in any way.
Therefore the definition of truth as full and exhaustive knowledge about such complex organized system of the world, believing such truth by absolute, absurdly on several reasons.
In particular, it is impossible to exhaust knowledge, inasmuch process of cognition so vast in the relations even only the Universe known to us is boundless. Besides that, process of cognition by the person is limited by five sense organs and opportunities of his cogitative apparatus.
