12. Knowledge Sources / A. A Priori Knowledge / 1. Nature of the A Priori

6982	Long arithmetic calculations show the a priori can be fallible [Jackson]
	Full Idea: We know that being fallible and being a priori can co-exist - the results of long numerical additions are well-known examples.
	From: Frank Jackson (From Metaphysics to Ethics [1998], Ch.2)
	A reaction: I see this realisation as a good example of progress in philosophy. Russell, who says self-evidence comes in degrees, deserves major credit. It is the key idea that once again makes rationalism respectable.

12. Knowledge Sources / B. Perception / 2. Qualities in Perception / a. Qualities in perception

6991	We examine objects to determine colour; we do not introspect [Jackson]
	Full Idea: We examine objects to determine their colour; we do not introspect.
	From: Frank Jackson (From Metaphysics to Ethics [1998], Ch.3)
	A reaction: Interesting, but the theory of secondary qualities did not arise from experience, but from a theory about what is actually going on. Compare pain appearing to be in your foot.
