Centering on Demonstrative Thought

The nature of perceptual demonstratives, the ‘that F’ component of judgments of the form ‘that F is G’ based on perceptual input, has been a topic of interest for many philosophers. Another related, though distinct, question concerns the nature of demonstrative judgments based not on current perceptual input, but instead derived from memory. I argue that the account put forward by John Campbell fails to adequately account for memory-based demonstrative thought.
