A Solution to Fine's Paradox of a Variable
In [2] Kit Fine formulated the paradox of a variable. Roughly, it isolates a conflict between two intuitions concerning the semantic role of a variable. According to the first intuition a semantic role of a variable is exhausted by the range of its values. Consequently, any two variables turn out to be synonymous. On the other hand, in the context of an expression (a formula and/or polynomial), it happens that distinct variables play a different semantic role. Hence, a contradiction. In the first part of the talk we zoom in the structure of Fine’s reasoning and abstract away from the Fine’s example. As the outcome, we extract tacit assumptions, which lead to the paradox. These assumptions are principle of compositionality and...
