For what possible worlds actually are (and virtually no one, perhaps not even Lewis, accepted their reality) does not affect the brilliant, sophisticated way he used them, analysing problematic notions in causation, universals, the content of thought, properties, probability, and the nature of propositions.
But many theorists contend that functions from worlds to truth-values cannot fully capture the content of thought and talk.
As a start we may note: the content of thought, in this sense, is what is reported when answering the question, 'What does she think?' by something of the form, 'She thinks that p.' And the content of thought is what two people are said to share, when they are said to think the same thought.
To the best of our knowledge, the finding that cognitive symptoms (speed and content of thought) are more prominent in adults compared to younger age groups has not been reported previously.
Rand rejects Kant's idea of innate conceptual categories on the grounds that it confuses the form of thought with the object and content of thought, thus cutting us off from reality (IOE, Ch. 8).
and the determination of their contents (how they come to be about what they are about), and the existence of phenomenal properties and their relation to the content of thought and perceptual experience.
They abstract away from the semantic content of thoughts or claims, to leave only semantic structure.
N.B., the discussion varies in speaking sometimes of the content of concepts, and other times of the content of thoughts.
These entities constitute a certain uniform domain, which can be viewed as a subdomain of Frege's so-called "third realm" (the realm of the objective content of thoughts, and generally abstract objects of various kinds, see Frege 1918, cf. Popper 1972 and also Burge 1992, 634).
Traditional CT assumes that change of the negative content of thoughts and attitudes are crucial features of successful interventions.
