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. |

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. |
430 | Senses are no use if the soul is corrupt [Heraclitus] |

1500 | When we sleep, reason closes down as the senses do [Heraclitus, by Sext.Empiricus] |

From: report of Heraclitus (fragments/reports [c.500 BCE], A16) by Sextus Empiricus - Against the Professors (six books) 7.130 |
