1564 | True and false statements can use exactly the same words [Anon (Diss)] |
Full Idea: There is no difference between a true statement and a false statement, because they can use exactly the same words. | |
From: Anon (Diss) (Dissoi Logoi - on Double Arguments [c.401 BCE], §4) |
14596 | Call 'nominalism' the denial of numbers, properties, relations and sets [Dorr] |
Full Idea: Just as there are no numbers or properties, there are no relations (like 'being heavier than' or 'betweenness'), or sets. I will provisionally use 'nominalism' for the conjunction of these four claims. | |
From: Cian Dorr (There Are No Abstract Objects [2008], 1) | |
A reaction: If you are going to be a nominalist, do it properly! My starting point in metaphysics is strong sympathy with this view. Right now [Tues 22nd Nov 2011, 10:57 am GMT] I think it is correct. |
14597 | Natural Class Nominalism says there are primitive classes of things resembling in one respect [Dorr] |
Full Idea: Natural Class Nominalists take as primitive the notion of a 'natural' class - a class of things that all resemble one another in some one respect and resemble nothing else in that respect. | |
From: Cian Dorr (There Are No Abstract Objects [2008], 4) | |
A reaction: Dorr rejects this view because he doesn't believe in 'classes'. How committed to classes do you have to be before you are permitted to talk about them? All vocabulary (such as 'resemble') seems metaphysically tainted in this area. |
14598 | Abstracta imply non-logical brute necessities, so only nominalists can deny such things [Dorr] |
Full Idea: If there are abstract objects, there are necessary truths about these things that cannot be reduced to truths of logic. So only the nominalist, who denies that there are any such things, can adequately respect the idea that there are no brute necessities. | |
From: Cian Dorr (There Are No Abstract Objects [2008], 4) | |
A reaction: This is where two plates of my personal philosophy grind horribly against one another. I love nominalism, and I love natural necessities. They meet like a ring-species in evolution. I'll just call it a 'paradox', and move on (swiftly). |
1559 | Thracians think tattooing adds to a girl's beauty, but elsewhere it is a punishment [Anon (Diss)] |
Full Idea: Thracians think that tattooing enhances a girl's beauty, whereas for everyone else tattooing is a punishment for a crime. | |
From: Anon (Diss) (Dissoi Logoi - on Double Arguments [c.401 BCE], §2) |
1561 | Anything can be acceptable in some circumstances and unacceptable in others [Anon (Diss)] |
Full Idea: Anything can be acceptable under the right circumstances, and unacceptable under the wrong circumstances. | |
From: Anon (Diss) (Dissoi Logoi - on Double Arguments [c.401 BCE], §2) |
1560 | Lydians prostitute their daughters to raise a dowery, but no Greek would marry such a girl [Anon (Diss)] |
Full Idea: The Lydians find it acceptable for their daughters to work as prostitutes to raise money for getting married, but no one in Greece would be prepared to marry such a girl. | |
From: Anon (Diss) (Dissoi Logoi - on Double Arguments [c.401 BCE], §2) |
1567 | How could someone who knows everything fail to act correctly? [Anon (Diss)] |
Full Idea: If someone knows the nature of everything, how could he fail to be able also to act correctly in every case? | |
From: Anon (Diss) (Dissoi Logoi - on Double Arguments [c.401 BCE], §8) |
1563 | Every apparent crime can be right in certain circumstances [Anon (Diss), by PG] |
Full Idea: It can be right, in certain circumstances, to steal, to break a solemn promise, to rob temples, and even (as Orestes did) to murder one's nearest and dearest. | |
From: report of Anon (Diss) (Dissoi Logoi - on Double Arguments [c.401 BCE], §3) by PG - Db (ideas) | |
A reaction: Not sure about the last one! I suppose you can justify any hideousness if the fate of the universe depends on it. It must be better to die than the perform certain extreme deeds. |
1562 | It is right to lie to someone, to get them to take medicine they are reluctant to take [Anon (Diss)] |
Full Idea: It is right to lie to your parents, in order to get them to take a good medicine they are reluctant to take. | |
From: Anon (Diss) (Dissoi Logoi - on Double Arguments [c.401 BCE], §3) | |
A reaction: I dread to think what the medicines were which convinced the writer of this. A rule such as this strikes me as dangerous. Justifiable in extreme cases. House on fire etc. |
1566 | The first priority in elections is to vote for people who support democracy [Anon (Diss)] |
Full Idea: A lottery is not democratic, because every state contains people who are not democratic, and if the lottery chooses them they will destroy the democracy. People should elect those who are observed to favour democracy. | |
From: Anon (Diss) (Dissoi Logoi - on Double Arguments [c.401 BCE], §7) |
1565 | We learn language, and we don't know who teaches us it [Anon (Diss)] |
Full Idea: We learn language, and we don't know who teaches us it. | |
From: Anon (Diss) (Dissoi Logoi - on Double Arguments [c.401 BCE], §6) |
1748 | Archelaus was the first person to say that the universe is boundless [Archelaus, by Diog. Laertius] |
Full Idea: Archelaus was the first person to say that the universe is boundless. | |
From: report of Archelaus (fragments/reports [c.450 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 02.Ar.3 |
5989 | Archelaus said life began in a primeval slime [Archelaus, by Schofield] |
Full Idea: Archelaus wrote that life on Earth began in a primeval slime. | |
From: report of Archelaus (fragments/reports [c.450 BCE]) by Malcolm Schofield - Archelaus | |
A reaction: This sounds like a fairly clearcut assertion of the production of life by evolution. Darwin's contribution was to propose the mechanism for achieving it. We should honour the name of Archelaus for this idea. |
