A PRINCIPLE OF RELATIVITY means a principle of identity, principle of one-quality, principle of the same-sex medium, principle of inconspicuousness. In a word, a principle of relativity means principle of indefiniteness and, then, principle of incognizability (be searched and recognize a white stain on a white screen is nonsense). A PRINCIPLE OF OPPOSITES means a principle of duality (of dualism), principle of polarity, principle of the androgynous model, principle of difference. In a word, a principle of opposite means principle of definiteness of the one by the other and, then, principle of winning picks (the difference between two objects makes them identifiable). It is clearly seen that the presented two principles are incompatible. The moving relative to one another inertial systems are subordinate or on relativity (indefiniteness) or on opposite (definiteness). Another possibility does not exist. One of the principles should be insolvent. To this factual situation, Einstein approached in the following way: First at the base of the study put the principle of relativity for absolute identity of the inertial systems (the same two systems are moving relative to one another). But then does not start to build Theory on the condition for their full equality, as required by this principle, and passes to the principle of opposite by introducing the opposition "stationary system-a system in motion" (the one system is moving relative to the other)...
