13. Knowledge Criteria / C. External Justification / 1. External Justification
Externalist accounts of knowledge do not require the traditional sort of justification [Kornblith]
     Full Idea: What is distinctive about externalist accounts of knowledge is that they do not require justification, at least in the traditional sense.
     From: Hilary Kornblith (Internalism and Externalism: a History [2001], p.2)
     A reaction: At least this gives animals the chance to know things, but I suspect that they never get beyond true beliefs. I'm sure humans have 'better' knowledge than animals.
26. Natural Theory / A. Speculations on Nature / 6. Early Matter Theories / c. Ultimate substances
Pherecydes said the first principle and element is earth [Pherecydes, by Sext.Empiricus]
     Full Idea: Pherecydes of Syros said that the principle and element of all things is earth.
     From: report of Pherecydes (fragments/reports [c.600 BCE]) by Sextus Empiricus - Against the Physicists (two books) I.360
     A reaction: Sextus is giving the history, and mentions it before saying that Thales thought it was water. Earth seems a sensible starting point, and I am guessing that Thales was trying to think a bit more deeply than Pherecydes about it.
27. Natural Reality / B. Modern Physics / 1. Relativity / a. Special relativity
Motion is not absolute, but consists in relation [Leibniz]
     Full Idea: In reality motion is not something absolute, but consists in relation.
     From: Gottfried Leibniz (On Motion [1677], A6.4.1968), quoted by Daniel Garber - Leibniz:Body,Substance,Monad 3
     A reaction: It is often thought that motion being relative was invented by Einstein, but Leibniz wholeheartedly embraced 'Galilean relativity', and refused to even consider any absolute concept of motion. Acceleration is a bit trickier than velocity.
29. Religion / D. Religious Issues / 2. Immortality / a. Immortality
Pherecydes was the first to say that the soul is eternal [Pherecydes, by Cicero]
     Full Idea: As far as the literature tells us, Pherecydes of Syros was the first who pronounced the souls of men to be eternal.
     From: report of Pherecydes (fragments/reports [c.600 BCE]) by M. Tullius Cicero - Tusculan Disputations I.xvi.38
     A reaction: Presumably before that it was the physical person who arrived in the Underworld. The Hindu tradition seems to require the soul to be very long-lived, if not eternal. Why did Pherecydes come up with this idea?
