7435 | Dispositions are second-order properties, the property of having some property [Jackson/Pargetter/Prior, by Armstrong] |
Full Idea: It was proposed that dispositions are second-order properties of objects: the property of having some property. | |
From: report of Jackson/Pargetter/Prior (Three theses about dispositions [1982]) by David M. Armstrong - Pref to new 'Materialist Theory' p.xvii | |
A reaction: It seems more plausible to say that dispositions are first-order properties - that is, properties are dispositions, which are causal powers. A disposition to smoke is to have a causal power which leads to smoking. |
20543 | 'Social justice' is a confused idea, and inequalities need no justification [Hayek, by Swift] |
Full Idea: Hayek thinks the whole idea of social justice involves a philosophical mistake, so that inequality doesn't really need justification in the first place. | |
From: report of F.A. Hayek (The Mirage of Social Justice [1976]) by Adam Swift - Political Philosophy (3rd ed) 1 'Conc' | |
A reaction: It is certainly hard to justify the claim that the state of nature involves equality, making its disturbance in need of justification. But surely inequalities in government policy (such as differential income tax) need justification? |
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. |
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. |
