Leistung, which, moreover, would be declared completely superfluous in determining experience. Cassirer's interpretation is quite clear on the latter point: the theory of relativity falls on the ground of transcendental philosophy, since the preliminary physical determination must be prefaced with an analysis of the judgements we use to express the main physical notions, for instance, the famous "simultaneity': even if the physical definition of simultaneity must be established solely in the field of physics, considering the limitations implied by the speed of light, a preliminary assumption regarding the concept of a "normal" definition of simultaneity is required, which depends upon some invariable functions of the intellect. Through this interpretation, and notwithstanding the endorsement of the empirical side of relativity, the priority of a pure transcendental moment against the first stratum of a physical determination must be upheld. In arguing the renewed necessity of this quite standard transcendental approach, I will try a peculiar comparison between Cassirer's point of view and two of the most important theories of experience of the 20th century, viz. Husserl's theory of Lebenswelt and the description of experimental reality attempted by the Copenhagen interpretation of quantum mechanics." /> The conditions of possibility of scientific experience - Laino Luigi | sdvig press
