9455 | Maybe proper names have the content of fixing a thing's category [Bealer] |
Full Idea: Some say that proper names have no descriptive content, but others think that although a name does not have the right sort of descriptive content which fixes a unique referent, it has a content which fixes the sort or category to which it belongs. | |
From: George Bealer (Propositions [1998], §7) | |
A reaction: Presumably 'Mary', and 'Felix', and 'Rover', and 'Smallville' are cases in point. There is a well known journalist called 'Manchester', a famous man called 'Hilary', a village in Hertfordshire called 'Matching Tie'... Interesting, though. |
9454 | The four leading theories of definite descriptions are Frege's, Russell's, Evans's, and Prior's [Bealer] |
Full Idea: The four leading theories of definite descriptions are Frege's, Russell's, Evans's, and Prior's, ...of which to many Frege's is the most intuitive of the four. Frege says they refer to the unique item (if it exists) which satisfies the predicate. | |
From: George Bealer (Propositions [1998], §5) | |
A reaction: He doesn't expound the other three, but I record this a corrective to the view that Russell has the only game in town. |
9453 | Sentences saying the same with the same rigid designators may still express different propositions [Bealer] |
Full Idea: The propositions behind 'Cicero is emulated more than Tully' seems to differ somehow from 'Tully is emulated more than Cicero', despite the proper names being rigid designators. | |
From: George Bealer (Propositions [1998], §1) | |
A reaction: Interesting, because this isn't a directly propositional attitude situation like 'believes', though it depends on such things. Bealer says this is a key modern difficulty with propositions. |
9452 | Propositions might be reduced to functions (worlds to truth values), or ordered sets of properties and relations [Bealer] |
Full Idea: The reductionist view of propositions sees them as either extensional functions from possible worlds to truth values, or as ordered sets of properties, relations, and perhaps particulars. | |
From: George Bealer (Propositions [1998], §1) | |
A reaction: The usual problem of all functional accounts is 'what is it about x that enables it to have that function?' And if they are sets, where does the ordering come in? A proposition isn't just a list of items in some particular order. Both wrong. |
9451 | Modal logic and brain science have reaffirmed traditional belief in propositions [Bealer] |
Full Idea: Philosophers have been skeptical about abstract objects, and so have been skeptical about propositions,..but with the rise of modal logic and metaphysics, and cognitive science's realism about intentional states, traditional propositions are now dominant. | |
From: George Bealer (Propositions [1998], §1) | |
A reaction: I personally strongly favour belief in propositions as brain states, which don't need a bizarre ontological status, but are essential to explain language, reasoning and communication. |
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. |
20890 | Why do sexual relationships need permanence, if other relationships don't? [Punzo] |
Full Idea: What is the reason for demanding permanence in the relationship of sexual partners when we do not see such permanence as being importance to other human relationships? | |
From: Vincent C. Punzo (Morality and Human Sexuality [1969], p.220) | |
A reaction: The distinction may not be that simple. 'Loyalty' must certainly be mentioned. Friends can legitimately drift apart, but to desert a close friend at a time of great need might be as great a crime as adultery. When is loyalty particularly needed? |
20891 | Does engaging in sexual intercourse really need no more thought than playing tennis? [Punzo] |
Full Idea: It seems strange for a man and a woman to give no more thought to the question of whether they should engage in sexual intercourse than to the question of whether they shoud play tennis. | |
From: Vincent C. Punzo (Morality and Human Sexuality [1969], p.221) | |
A reaction: This strikes me as a reasonable point, but times have moved on since 1969, and for plenty of people nowadays playing tennis is a bigger issue than having sex, because of the time, equipment and effort involved. |
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. |
