2945 | Most philosophers start with reality and then examine knowledge; Descartes put the study of knowledge first [Lehrer] |
Full Idea: Some philosophers (e.g Plato) begin with an account of reality, and then appended an account of how we can know it, ..but Descartes turned the tables, insisting that we must first decide what we can know. | |
From: Keith Lehrer (Theory of Knowledge (2nd edn) [2000], I p.2) |
20728 | Metaphysics is hopeless with its present epistemology; common-sense realism is needed [Colvin] |
Full Idea: Despair over metaphysics will not change until it has shaken off the incubus of a perverted epistemology, which has left thought in a hopeless tangle - until common-sense critical realism is made the starting point for investigating reality. | |
From: Stephen S. Colvin (The Common-Sense View of Reality [1902], p.144) | |
A reaction: It seems to me that this is what has happened to analytic metaphysics since Kripke. Careful discussions about the nature of an object, or a category, or a property, are relying on unquestioned robust realism. Quite right too. |
2946 | You cannot demand an analysis of a concept without knowing the purpose of the analysis [Lehrer] |
Full Idea: An analysis is always relative to some objective. It makes no sense to simply demand an analysis of goodness, knowledge, beauty or truth, without some indication of the purpose of the analysis. | |
From: Keith Lehrer (Theory of Knowledge (2nd edn) [2000], I p.7) | |
A reaction: Your dismantling of a car will go better if you know what a car is for, but you can still take it apart in ignorance. |
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) |
20726 | We can only distinguish self from non-self if there is an inflexible external reality [Colvin] |
Full Idea: Were there no inflexible reality outside of the individual, opposing and limiting it, knowledge of the self and the non-self would never develop. | |
From: Stephen S. Colvin (The Common-Sense View of Reality [1902], p.140) | |
A reaction: Presumably opponents would have to say that such 'knowledge' is an illusion. This is in no way a conclusive argument, but I approach the problem of realism in quest of the best explanation, and this idea is important evidence. |
20727 | Common-sense realism rests on our interests and practical life [Colvin] |
Full Idea: It is the determination of the external world from the practical standpoint, from the standpoint of interest, that may be defined as the common-sense view of reality. | |
From: Stephen S. Colvin (The Common-Sense View of Reality [1902], p.141) | |
A reaction: Probably more appropriately named the 'pragmatic' view of reality. Relying on what is 'practical' seems to offer some objectivity, but relying on 'interest' rather less so. Can I be an anti-realist when life goes badly, and a realist when it goes well? |
20730 | If objects are doubted because their appearances change, that presupposes one object [Colvin] |
Full Idea: If objects are doubted because the same object appears differently at different times and circumstances, in order that this judgement shall have weight it must be assumed that the object under question is the same in its different presentations. | |
From: Stephen S. Colvin (The Common-Sense View of Reality [1902], p.145) | |
A reaction: [compressed] Scepticism could eat into the underlying object as well. Is the underlying object a 'substrate'? If so, what's that? Is the object just a bundle of a properties? If so, there is no underlying object. |
20729 | Arguments that objects are unknowable or non-existent assume the knower's existence [Colvin] |
Full Idea: Arguments for the absolute unknowability or non-existence of an external object only works by assuming that another external object, an individual, is known completely in so far as that individual expresses a judgement about an external object. | |
From: Stephen S. Colvin (The Common-Sense View of Reality [1902], p.145) | |
A reaction: Anti-realism is a decay that eats into everything. You can't doubt all the externals without doubting all the internals as well. |
20731 | The idea that everything is relations is contradictory; relations are part of the concept of things [Colvin] |
Full Idea: The doctrine [that all we can know is the relations between subject and object] is in its essence self-contradictory, since our very idea of thing implies that it is something in relation either actually or potentially. | |
From: Stephen S. Colvin (The Common-Sense View of Reality [1902], p.150) | |
A reaction: Ladyman and Ross try to defend an account of reality based entirely on relations. I'm with Colvin on this one. All accounts of reality based either on pure relations or pure functions have a huge hole in their theory. |
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) |
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) |
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) |
