13. Knowledge Criteria / C. External Justification / 8. Social Justification
If you would deny a truth if you know the full evidence, then knowledge has social aspects [Harman, by Sosa]
     Full Idea: If one reads of a genuine assassination, but then fails to read the reports next day which untruthfully deny the event, one probably does not know of the event. But we must conclude that knowledge has a further 'social aspect'.
     From: report of Gilbert Harman (Induction [1970], §IV) by Ernest Sosa - The Raft and the Pyramid Appx
     A reaction: I doubt if this is enough to support an externalist account of defeasibility. Wise people don't 'know' of an event after one report. For 24 hours the Royalists thought they had won Marston Moor! You know he's dead when you see the Zapruder film.
19. Language / A. Nature of Meaning / 4. Meaning as Truth-Conditions
Davidson rejected ordinary meaning, and just used truth and reference instead [Davidson, by Soames]
     Full Idea: Davidson held that knowledge of truth and reference could give us a notion of meaning. He embraced Quine's rejection of analyticity, synonymy and ordinary meaning, and substituted truth and reference, when there was something genuine to capture.
     From: report of Donald Davidson (Semantics for Natural Languages [1970]) by Scott Soames - Philosophy of Language 2.3
     A reaction: I always get a warm glow when anyone suggests that the concept of meaning involves the concept of truth. I largely reject Quine. Davidson made a helpful suggestion!
Davidson aimed to show that language is structured by first-order logic [Davidson, by Smart]
     Full Idea: Davidson's program was to show the underlying structure of natural languages as that of first-order logic.
     From: report of Donald Davidson (Semantics for Natural Languages [1970], 2) by J.J.C. Smart - The Tenseless Theory of Time 2
     A reaction: First order logic just reasons about a domain of objects with predicates attached to them. Language appears to refer to properties and relations as well as objects.
26. Natural Theory / A. Speculations on Nature / 5. Infinite in Nature
Archelaus was the first person to say that the universe is boundless [Archelaus, by Diog. Laertius]
     Full Idea: Archelaus was the first person to say that the universe is boundless.
     From: report of Archelaus (fragments/reports [c.450 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 02.Ar.3
27. Natural Reality / G. Biology / 3. Evolution
Archelaus said life began in a primeval slime [Archelaus, by Schofield]
     Full Idea: Archelaus wrote that life on Earth began in a primeval slime.
     From: report of Archelaus (fragments/reports [c.450 BCE]) by Malcolm Schofield - Archelaus
     A reaction: This sounds like a fairly clearcut assertion of the production of life by evolution. Darwin's contribution was to propose the mechanism for achieving it. We should honour the name of Archelaus for this idea.
