5 ideas

3. Truth / A. Truth Problems / 8. Subjective Truth
Choose the true hypothesis, which is the most intelligible one [Leibniz]
     Full Idea: One should choose the more intelligible hypothesis, and the truth is nothing but its intelligibility.
     From: Gottfried Leibniz (On Copernicanism and Relativity of Motion [1689], p.91)
     A reaction: This apparently simple observation strikes me as being rather profound. Our picture of the world is shaped entirely by what is intelligible to us. An odd notion of truth, though. The age of reason. See Idea 13158.
14. Science / D. Explanation / 1. Explanation / b. Aims of explanation
Scientific explanation aims at a unifying account of underlying structures and processes [Hempel]
     Full Idea: What theoretical scientific explanation aims at is an objective kind of insight that is achieved by a systematic unification, by exhibiting the phenomena as manifestations of common underlying structures and processes that conform to testable principles.
     From: Carl Hempel (Philosophy of Natural Science [1967], p.83), quoted by Laurence Bonjour - The Structure of Empirical Knowledge 5.3
     A reaction: This is a pretty good statement of scientific essentialism, and structures and processes are what I take Aristotle to have had in mind when he sought 'what it is to be that thing'. Structures and processes give stability and powers.
14. Science / D. Explanation / 3. Best Explanation / a. Best explanation
The Copernican theory is right because it is the only one offering a good explanation [Leibniz]
     Full Idea: The Copernican account is the truest theory, that is, the most intelligible theory and the only one capable of an explanation sufficient for a person of sound reason.
     From: Gottfried Leibniz (On Copernicanism and Relativity of Motion [1689], p.92)
     A reaction: The word 'intelligible' here seems to be linked to the notion of a best explanation.
25. Social Practice / E. Policies / 5. Education / b. Education principles
Learned men gain more in one day than others do in a lifetime [Posidonius]
     Full Idea: In a single day there lies open to men of learning more than there ever does to the unenlightened in the longest of lifetimes.
     From: Posidonius (fragments/reports [c.95 BCE]), quoted by Seneca the Younger - Letters from a Stoic 078
     A reaction: These remarks endorsing the infinite superiority of the educated to the uneducated seem to have been popular in late antiquity. It tends to be the religions which discourage great learning, especially in their emphasis on a single book.
27. Natural Reality / D. Time / 1. Nature of Time / d. Time as measure
Time is an interval of motion, or the measure of speed [Posidonius, by Stobaeus]
     Full Idea: Posidonius defined time thus: it is an interval of motion, or the measure of speed and slowness.
     From: report of Posidonius (fragments/reports [c.95 BCE]) by John Stobaeus - Anthology 1.08.42
     A reaction: Hm. Can we define motion or speed without alluding to time? Looks like we have to define them as a conjoined pair, which means we cannot fully understand either of them.
