Abstract

The transformation of the relations between reflection and reality and between concepts and their correspondent objects into themes represents even in the present a field for most heated discussions. The joining of conceptual schemes corresponding to the intellect and reality represents a problem which is still to be solved. A solution to this problem was proposed by R. Carnap in his extremely ambitious project from Der logische Aufbau der Welt (1928). Overlooked for a long time, this work has returned to the philosophical spotlight in recent years, because philosophers finally realized that Carnap’s project comprises almost allthe major themes of contemporary epistemology, such as the relation between theory and reality, between concepts and experience, the major lines of a phenomenology and of a “logic of experience” or the status of language and of the concepts of science. Situated at the confluence of some philosophical traditions such as neo-kantian philosophy, the logical analysis of Russell and Wittgenstein, but also phenomenology, Carnap’s program in Aufbau starts from some premises such: the need to control experience (= major stake of any scientific knowledge); the orientation towards form of the modern concept of scientific knowledge (under Kant’s direct influence); the assertion of a concept of knowledge mostly relational or structural (issue resulted in the orientation towards form of modern knowledge); the need for a methodology engaged in a constructive way and modelled on mathematical thinking; our reporting to the instance of sensitivity in the formation of experience (under E. Mach’s influence).
