13. Knowledge Criteria / C. External Justification / 3. Reliabilism / a. Reliable knowledge
Belief is knowledge if it is true, certain, and obtained by a reliable process [Ramsey]
     Full Idea: I have always said that a belief was knowledge if it was (i) true, (ii) certain, (iii) obtained by a reliable process.
     From: Frank P. Ramsey (Knowledge [1929]), quoted by Juan Comesaņa - Reliabilism 2
     A reaction: Remarkable to be addressing the Gettier problem at that date, but Russell had flirted with the problem. Ramsey says the production of the belief must be reliable, rather than the justification for the belief. Note that he wants certainty.
14. Science / D. Explanation / 2. Types of Explanation / j. Explanations by reduction
You can only explain the qualities of large objects using entities which lack those qualities [Heisenberg]
     Full Idea: It is impossible to explain the manifest qualities of ordinary middle-sized objects except by tracing these back to the behaviour of entities which themselves no longer possess these qualities.
     From: Werner Heisenberg (Ancient Thought in Modern Physics [1937], p.119), quoted by William Lycan - Consciousness 8.10
     A reaction: Compare the similar wonderful remark by Lucretius (Idea 5713). If we accept this as a general principle for all of nature (including us) - and I do - then it is silly to complain that consciousness isn't found in basic physics.
27. Natural Reality / G. Biology / 3. Evolution
Darwin's idea was the best idea ever [Dennett]
     Full Idea: If I were to give an award for the single best idea anyone has ever had, I'd give it to Darwin.
     From: Daniel C. Dennett (Darwin's Dangerous Idea [1995], §1.1)
