12. Knowledge Sources / B. Perception / 4. Sense Data / a. Sense-data theory
Maybe 'sense-data' just help us to talk about unusual perceptual situations [Lacey]
     Full Idea: One possibility is that talk of sense-data is a mere linguistic convenience, providing a noun for talking about appearances, as when seeing a red object in sodium light (when it looks grey).
     From: A.R. Lacey (A Dictionary of Philosophy [1976], p.196)
     A reaction: The term seems to have been coined to deal with situations where there is a gap between appearance and presumed reality, as in illusions. Maybe illusions prove the existence of sense-data, rather than it being a 'convenient' term.
12. Knowledge Sources / B. Perception / 4. Sense Data / b. Nature of sense-data
Where do sense-data begin or end? Can they change? What sort of thing are they? [Lacey]
     Full Idea: It is hard to individuate sense-data, saying where one ends and the next begins, and hard to say whether they can change; are they substances, qualities, events, or what?
     From: A.R. Lacey (A Dictionary of Philosophy [1976], p.196)
     A reaction: The problem is not that these questions are unanswerable. The answer seems to be either that they are physical and external, or that they are mental and internal, and that there is no ontological space for them between the two.
Some claim sense-data are public, and are parts of objects [Lacey]
     Full Idea: Sometimes it is said that sense-data are public, and parts either of objects or of the surfaces of objects.
     From: A.R. Lacey (A Dictionary of Philosophy [1976], p.196)
     A reaction: This suggests two drastically different theories, one making sense-data into mental events, the other placing them in the 'external' world. The latter theory can dovetail them with the physics, but then why would we need them?
22. Metaethics / C. The Good / 2. Happiness / d. Routes to happiness
Mill wondered if he would be happy if all his aims were realised, and answered no [Mill, by Critchley]
     Full Idea: Mill, in his crisis of 1827, asked himself whether he would be happy if all his objects in life were realised, and had to answer that he would not.
     From: report of John Stuart Mill (Autobiography [1870]) by Simon Critchley - Continental Philosophy - V. Short Intro Ch.3
     A reaction: The reply is either that happiness is in the striving, or that his aims in life were wrong, or that happiness is impossible. It seems to contradict Kant's definition (Idea 1452).
29. Religion / B. Monotheistic Religion / 4. Christianity / d. Heresy
Heretics should be eradicated like wolves [Aquinas]
     Full Idea: Heretics are wolves …and therefore ought to be eradicated.
     From: Thomas Aquinas (Sentences [1264], IV.13.2.3sc), quoted by Robert Pasnau - Metaphysical Themes 1274-1671 20.2
