17950 | The logos enables us to track one particular among a network of objects [Nehamas] |
Full Idea: The logos (the definition) is a summary statement of the path within a network of objects that one will have to follow in order to locate a particular member of that network. | |
From: Alexander Nehamas (Episteme and Logos in later Plato [1984], p.234) | |
A reaction: I like this because it confirms that Plato (as well as Aristotle) was interested in the particulars rather than in the kinds (which I take to be general truths about particulars). |
17951 | A logos may be short, but it contains reference to the whole domain of the object [Nehamas] |
Full Idea: A thing's logos, apparently short as it may be, is implicitly a very rich statement since it ultimately involves familiarity with the whole domain to which that particular object belongs. | |
From: Alexander Nehamas (Episteme and Logos in later Plato [1984], p.234) | |
A reaction: He may be wrong that the logos is short, since Aristotle (Idea 12292) says a definition can contain many assertions. |
468 | Musical performance can reveal a range of virtues [Damon of Ath.] |
Full Idea: In singing and playing the lyre, a boy will be likely to reveal not only courage and moderation, but also justice. | |
From: Damon (fragments/reports [c.460 BCE], B4), quoted by (who?) - where? |
21236 | Instead of gravitational force, we now have a pervasive gravitational field [Farmelo] |
Full Idea: Physics replaced the notion that bodies exert gravitational force on each other by the more effective picture that the bodies in the universe give rise to a pervasive gravitational field which exerts a force on each particle. | |
From: Graham Farmelo (The Strangest Man [2009], 08) | |
A reaction: This still uses the word 'force'. I sometimes get the impression that gravity is the curvature of space, but gravity needs more. Which direction along the curvature are particles attracted? The bottom line is the power of the bodies. |
21235 | The Schrödinger waves are just the maths of transforming energy values to positions [Farmelo] |
Full Idea: Dirac showed that the Schrödinger waves were simply the mathematical quantities involved in transforming the description of a quantum based on its energy values to one based on possible values of its position. | |
From: Graham Farmelo (The Strangest Man [2009], 08) | |
A reaction: Does this eliminate actual physical 'waves' from the theory? |
21234 | Experiments show that fundamental particles of one type are identical [Farmelo] |
Full Idea: It is an established experimental fact ...that every single fundamental particle in the universe is the same and identical to all other particles of the same type. | |
From: Graham Farmelo (The Strangest Man [2009], 07) | |
A reaction: A loud groan is heard from the tomb of Leibniz. I'm unclear how experiments can establish this. If electrons have internal structure (which is not ruled out) then uniformity is highly unlikely. |
