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)

12. Knowledge Sources / D. Empiricism / 1. Empiricism

21309	A proposition cannot be intelligible or consistent, if the perceptions are not so [Hume]
	Full Idea: No proposition can be intelligible or consistent with regard to objects, which is not so with regard to perceptions.
	From: David Hume (Treatise of Human Nature, + Appendix [1740], Appendix)
	A reaction: An interesting variant on expressions of the empiricist principle. Presumably one can say intelligible things about Escher drawings.
