11195 | If affirmative propositions express being, we affirm about what is absent [Aquinas] |
Full Idea: If being is what makes propositions true, then anything we can express in an affirmative proposition, however unreal, is said to be; so lacks and absences are, since we say that absences are opposed to presences, and blindness exists in an eye. | |
From: Thomas Aquinas (De Ente et Essentia (Being and Essence) [1267], p.92) | |
A reaction: See Idea 11194 for the alternative Aristotelian approach to being, according to categories. Do absences and lacks have real essences, or causal properties? The absence of the sentry may cause the loss of the city. |
6280 | Realism is a theory, which explains the convergence of science and the success of language [Putnam] |
Full Idea: Realism is an empirical theory; it explains the convergence of scientific theories, where earlier theories are often limiting cases of later theories (which is why theoretical terms preserve their reference); and it explains the success of language. | |
From: Hilary Putnam (Meaning and the Moral Sciences [1978], Pt Four) | |
A reaction: I agree. Personally, I think of Plato's Theory of Forms and all religions as empirical theories. The response from anti-realists is generally to undermine confidence in the evidence which these 'empirical theories' are said to explain. |
