Theory of Sign and Meaning
A world is the in-between between the Firstness and the Secondness. In this in-between a world is generated (first, a seed is given), and internal to this world there is a system of signs, which conforms to their own logic, "the internal logic of the topos". From the syntactic structure, after dualization, a semantics is given. The semantic picture is the dual of the syntactic structure that embodies the logic.
The logic is prior and hence its semantics is generated - otherwise there is no time and no dynamics.
Meaning reveals itself in the process of the generation of the semantic world. It is the Thirdness.
