Filosofia da Linguagem: Ep. 7: O verdadeiro e o falso

Value of the Information & Strength of the Argument

The lecture provides a clear and detailed exposition of Frege’s argument for truth values as the references of sentences. Ruffino carefully reconstructs the argument step by step, using concrete examples to illustrate the points. He also addresses potential objections and mentions alternative perspectives, such as Searle’s, which adds depth to the discussion. The argumentation is solid and faithful to Frege’s original ideas, making it valuable for students and enthusiasts of philosophy of language.
