8. Modes of Existence / E. Nominalism / 1. Nominalism / c. Nominalism about abstracta
17619 We renounce all abstract entities [Goodman/Quine]
     Full Idea: We do not believe in abstract entities..... We renounce them altogether.
     From: Goodman,N/Quine,W (Steps Towards a Constructive Nominalism [1947], p.105), quoted by Penelope Maddy - Defending the Axioms
     A reaction: Goodman always kept the faith here, but Quine decided to embrace sets, as a minimal commitment to abstracta needed for mathematics, which was needed for science. My sympathies are with Goodman. This is the modern form of 'nominalism'.
10. Modality / A. Necessity / 4. De re / De dicto modality
16079 De re modal predicates are ambiguous [Lewis, by Rudder Baker]

     From: report of David Lewis (Survival and Identity, with postscript [1983]) by Lynne Rudder Baker - Why Constitution is not Identity n25

12. Knowledge Sources / B. Perception / 4. Sense Data / a. Sense-data theory
2615 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)
