11. Knowledge Aims / C. Knowing Reality / 2. Phenomenalism
Modern phenomenalism holds that objects are logical constructions out of sense-data [Ayer]
     Full Idea: Nowadays phenomenalism is held to be a theory of perception which says that physical objects are logical constructions out of sense-data.
     From: A.J. Ayer (Phenomenalism [1947], §1)
12. Knowledge Sources / B. Perception / 4. Sense Data / a. Sense-data theory
The concept of sense-data allows us to discuss appearances without worrying about reality [Ayer]
     Full Idea: The introduction of the term 'sense-datum' is a means of referring to appearances without prejudging the question of what it is, if anything, that they are appearances of.
     From: A.J. Ayer (Phenomenalism [1947], §1)
22. Metaethics / B. Value / 2. Values / f. Altruism
The just man does not harm his enemies, but benefits everyone [Plato]
     Full Idea: First, Socrates, you told me justice is harming your enemies and helping your friends. But later it seemed that the just man, since everything he does is for someone's benefit, never harms anyone.
     From: Plato (Clitophon [c.372 BCE], 410b)
     A reaction: Socrates certainly didn't subscribe to the first view, which is the traditional consensus in Greek culture. In general Socrates agreed with the views later promoted by Jesus.
27. Natural Reality / A. Classical Physics / 1. Mechanics / d. Gravity
Gravity isn't a force, because it produces effects without diminishing [Mayer]
     Full Idea: If gravity be called a force, a cause is supposed which produces effects without itself diminishing, and incorrect conceptions of the causal connexions of things are thereby fostered.
     From: J.R. Mayer (Remarks on the forces of inorganic Nature [1842], p.199), quoted by Brian Ellis - Scientific Essentialism 8.03
     A reaction: This seems like a brilliant prelude to the proposal that gravity is actually the 'curvature' of space (whatever that is!).
