12156 | Aesthetics has risen and fallen with Romanticism [Scruton] |
Full Idea: The rise and fall (as we presently perceive them) of aesthetics have been contemporaneous with the rise and fall of Romanticism. | |
From: Roger Scruton (Recent Aesthetics in England and America [1980], p.3) | |
A reaction: Maybe it started a little before Romanticism, as part of the Englightenment aim of being rational about everything, and maybe it survives Romanticism because we want to be scientific about everything. |
12158 | Aesthetic experience informs the world with the values of the observer [Scruton] |
Full Idea: It is possible to conclude that aesthetic experience has a peculiar practical significance: it represents the world as informed by the values of the observer. | |
From: Roger Scruton (Recent Aesthetics in England and America [1980], p.13) | |
A reaction: An excellent remark. If you look at, or listen to, anything, you can make a conscious effort to drain away your personal values (objectivity; science?), or you can consciously flood them with values. But moral and aesthetic vision must differ... |
13304 | 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. |
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. |
20820 | 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. |
