Logical analysis of natural language (LANL) based on TIL defines meaning (Frege’s sense) in a procedural way, resulting in the following thesis: The meaning of an expression is independent of context. The meaning (in the case of non-indexical expressions concept) is thus an abstract procedure, which is explicated in TIL as (well-defined) construction. What does depend on context is the way in which the meaning has to be handled. From this viewpoint we can distinguish three kinds of contexts: (i) hyper-intensional context; (ii) intensional context; (iii) extensional context.
