5. Theory of Logic / D. Assumptions for Logic / 3. Contradiction

10121	Contradiction is not a sign of falsity, nor lack of contradiction a sign of truth [Pascal]
	Full Idea: Contradiction is not a sign of falsity, nor the lack of contradiction a sign of truth.
	From: Blaise Pascal (works [1660]), quoted by A.George / D.J.Velleman - Philosophies of Mathematics Ch.6
	A reaction: [Quoted in Auden and Kronenberger's Book of Aphorisms] Presumably we would now say that contradiction is a purely formal, syntactic notion, and not a semantic one. If you hit a contradiction, something has certainly gone wrong.

12. Knowledge Sources / A. A Priori Knowledge / 10. A Priori as Subjective

3913	Maybe imagination is the source of a priori justification [Casullo]
	Full Idea: Some maintain that experiments in imagination are the source of a priori justification.
	From: Albert Casullo (A priori/A posteriori [1992], p.1)
	A reaction: What else could assessments of possibility and necessity be based on except imagination?

12. Knowledge Sources / B. Perception / 4. Sense Data / b. Nature of sense-data

22013	Subjects distinguish representations, as related both to subject and object [Reinhold]
	Full Idea: In consciousness the subject distinguishes the representation from the subject and object, and relates it to both.
	From: Karl Leonhard Reinhold (Foundations of Philosophical Knowledge [1791], p.78), quoted by Terry Pinkard - German Philosophy 1760-1860 04
	A reaction: This is a reminder that twentieth century analytic discussions of perception were largely recapitulating late Enlightenment German philosophy. This is a very good definition of sense-data. I can think about my representations. Reinhold was a realist.
