3. Truth / A. Truth Problems / 5. Truth Bearers
Davidson takes truth to attach to individual sentences [Davidson, by Dummett]
     Full Idea: Davidson, by contrast to Frege, has taken truth as attaching to linguistic items, that is, to actual or hypothetical token sentences.
     From: report of Donald Davidson (True to the Facts [1969]) by Michael Dummett - Truth and the Past 1
     A reaction: My personal notion of truth is potentially applicable to animals, so this doesn't appeal to me. I am happy to think of animals as believing simple propositions that never get as far as language, and being right or wrong about them.
3. Truth / H. Deflationary Truth / 2. Deflationary Truth
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)
6. Mathematics / A. Nature of Mathematics / 1. Mathematics
Mathematical truth is always compromising between ordinary language and sensible epistemology [Benacerraf]
     Full Idea: Most accounts of the concept of mathematical truth can be identified with serving one or another of either semantic theory (matching it to ordinary language), or with epistemology (meshing with a reasonable view) - always at the expense of the other.
     From: Paul Benacerraf (Mathematical Truth [1973], Intro)
     A reaction: The gist is that language pulls you towards platonism, and epistemology pulls you towards empiricism. He argues that the semantics must give ground. He's right.
6. Mathematics / C. Sources of Mathematics / 1. Mathematical Platonism / b. Against mathematical platonism
Realists have semantics without epistemology, anti-realists epistemology but bad semantics [Benacerraf, by Colyvan]
     Full Idea: Benacerraf argues that realists about mathematical objects have a nice normal semantic but no epistemology, and anti-realists have a good epistemology but an unorthodox semantics.
     From: report of Paul Benacerraf (Mathematical Truth [1973]) by Mark Colyvan - Introduction to the Philosophy of Mathematics 1.2
The platonist view of mathematics doesn't fit our epistemology very well [Benacerraf]
     Full Idea: The principle defect of the standard (platonist) account of mathematical truth is that it appears to violate the requirement that our account be susceptible to integration into our over-all account of knowledge.
     From: Paul Benacerraf (Mathematical Truth [1973], III)
     A reaction: Unfortunately he goes on to defend a causal theory of justification (fashionable at that time, but implausible now). Nevertheless, his general point is well made. Your theory of what mathematics is had better make it knowable.
13. Knowledge Criteria / E. Relativism / 4. Cultural relativism
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)
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)
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)
20. Action / C. Motives for Action / 3. Acting on Reason / b. Intellectualism
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)
22. Metaethics / A. Ethics Foundations / 2. Source of Ethics / j. Ethics by convention
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.
22. Metaethics / C. The Good / 1. Goodness / g. Consequentialism
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.
24. Political Theory / D. Ideologies / 5. Democracy / b. Consultation
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)
25. Social Practice / E. Policies / 5. Education / c. Teaching
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)
