343 | The unexamined life is not worth living for men [Socrates] |
Full Idea: The unexamined life is not worth living for men. | |
From: Socrates (reports of last days [c.399 BCE]), quoted by Plato - The Apology 38a | |
A reaction: I wonder why? I can see Nietzsche offering aristocratic heroes and dancers as counterexamples. Compare Idea 3798. |
8893 | For any given area, there seem to be a huge number of possible coherent systems of beliefs [Bonjour] |
Full Idea: The 2nd standard objection to coherence is 'alternative coherent systems' - that there will be indefinitely many possible systems of belief in relation to any given subject area, each as internally coherent as the others. | |
From: Laurence Bonjour (A Version of Internalist Foundationalism [2003], 3.2) | |
A reaction: This seems to imply that you could just invent an explanation, as long as it was coherent, but presumably good coherence is highly sensitive to the actual evidence. Bonjour observes that many of these systems would not survive over time. |
8888 | The concept of knowledge is so confused that it is best avoided [Bonjour] |
Full Idea: The concept of knowledge is seriously problematic in more than one way, and is best avoided as far as possible in sober epistemological discussion. | |
From: Laurence Bonjour (A Version of Internalist Foundationalism [2003], 1.5) | |
A reaction: Two sorts of states seem to be conflated: one where an animal has a true belief caused by an environmental event, and the other where a scholar pores over books and experiments to arrive at a hard-won truth. I say only the second is 'knowledge'. |
8887 | It is hard to give the concept of 'self-evident' a clear and defensible characterization [Bonjour] |
Full Idea: Foundationalists find it difficult to attach a clear and defensible content to the idea that basic beliefs that are characterized as 'self-justified' or 'self-evident'. | |
From: Laurence Bonjour (A Version of Internalist Foundationalism [2003], 1.4) | |
A reaction: A little surprising from a fan of a priori foundations, especially given that 'self-evident' is common usage, and not just philosophers' jargon. I think we can talk of self-evidence without a precise definition. We talk of an 'ocean' without trouble. |
8897 | The adverbial account will still be needed when a mind apprehends its sense-data [Bonjour] |
Full Idea: The adverbial account of the content of experience is almost certainly correct, because no account can be given of the relation between sense-data and the apprehending mind that is independent of the adverbial theory. | |
From: Laurence Bonjour (A Version of Internalist Foundationalism [2003], 5.1 n3) | |
A reaction: This boils down to the usual objection to sense-data, which is 'cut out the middle man'. Bonjour is right that at some point the mind has finally to experience whatever is coming in, and it must experience it in a particular way. |
8896 | Conscious states have built-in awareness of content, so we know if a conceptual description of it is correct [Bonjour] |
Full Idea: If we describe a non-conceptual conscious state, we are aware of its character via the constitutive or 'built-in' awareness of content without need for a conceptual description, and so recognise that a conceptually formulated belief about it is correct. | |
From: Laurence Bonjour (A Version of Internalist Foundationalism [2003], 4.3) | |
A reaction: This is Bonjour working very hard to find an account of primitive sense experiences which will enable them to function as 'basic beliefs' for foundations, without being too thin to do anything, or too thick to be basic. I'm not convinced. |
8891 | My incoherent beliefs about art should not undermine my very coherent beliefs about physics [Bonjour] |
Full Idea: If coherentism is construed as involving the believer's entire body of beliefs, that would imply, most implausibly, that the justification of a belief in one area (physics) could be undermined by serious incoherence in another area (art history). | |
From: Laurence Bonjour (A Version of Internalist Foundationalism [2003], 3.1) | |
A reaction: Bonjour suggests that a moderated coherentism is needed to avoid this rather serious problem. It is hard to see how a precise specification could be given of 'areas' and 'local coherence'. An idiot about art would inspire little confidence on physics. |
8892 | Coherence seems to justify empirical beliefs about externals when there is no external input [Bonjour] |
Full Idea: The 1st standard objection to coherence is the 'isolation problem', that contingent apparently-empirical beliefs might be justified in the absence of any informational input from the extra-conceptual world they attempt to describe. | |
From: Laurence Bonjour (A Version of Internalist Foundationalism [2003], 3.2) | |
A reaction: False beliefs can be well justified. In a perfect virtual reality we would believe our experiences precisely because they were so coherent. Messengers from the front line have top priority, but how do you detect infiltrators and liars? |
8894 | Coherentists must give a reason why coherent justification is likely to lead to the truth [Bonjour] |
Full Idea: The 3rd standard objection to coherence is the demand for a meta-justification for coherence, a reason for thinking that justification on the basis of the coherentist view of justification is in fact likely to lead to believing the truth. | |
From: Laurence Bonjour (A Version of Internalist Foundationalism [2003], 3.2) | |
A reaction: Some coherentists respond by adopting a coherence theory of truth, which strikes me as extremely unwise. There must be an underlying optimistic view, centred on the principle of sufficient reason, that reality itself is coherent. I like Idea 8618. |
8889 | Reliabilists disagree over whether some further requirement is needed to produce knowledge [Bonjour] |
Full Idea: Reliabilist views differ among themselves with regard to whether a belief's being produced in a reliable way is by itself sufficient for epistemic justification or whether there are further requirements that must be satisfied as well. | |
From: Laurence Bonjour (A Version of Internalist Foundationalism [2003], 2.1) | |
A reaction: If 'further requirements' are needed, the crucial question would be which one is trumps when they clash. If the further requirements can correct the reliable source, then it cannot any longer be called 'reliabilism'. It's Further-requirement-ism. |
8890 | If the reliable facts producing a belief are unknown to me, my belief is not rational or responsible [Bonjour] |
Full Idea: How can the fact that a belief is reliably produced make my acceptance of that belief rational and responsible when that fact itself is entirely unavailable to me? | |
From: Laurence Bonjour (A Version of Internalist Foundationalism [2003], 2.2) | |
A reaction: This question must rival Pollock's proposal (Idea 8815) as the master argument against externalism. Bonjour is assuming that knowledge has to be 'rational and responsible', but clearly externalists take a more lax view of knowledge. |
8895 | If neither the first-level nor the second-level is itself conscious, there seems to be no consciousness present [Bonjour] |
Full Idea: In the higher-order thought theory of consciousness, if the first-order thought is not itself conscious and the second-order thought is not itself conscious, then there seems to be no consciousness of the first-level content present at all. | |
From: Laurence Bonjour (A Version of Internalist Foundationalism [2003], 4.2) | |
A reaction: A nice basic question. The only plausible answer seems to be that consciousness arises out of the combination of levels. Otherwise one of the levels is redundant, or we are facing a regress. |
339 | Men fear death as a great evil when it may be a great blessing [Socrates] |
Full Idea: No one knows whether death may not be the greatest of all blessings for a man, yet men fear it as if they knew that it is the greatest of evils. | |
From: Socrates (reports of last days [c.399 BCE]), quoted by Plato - The Apology 29a | |
A reaction: As a neutral observer, I see little sign of it being a blessing, except as a relief from misery. It seem wrong to view such a natural thing as evil, but it is the thing most of us least desire. |
344 | If death is like a night of dreamless sleep, such nights are very pleasant [Socrates] |
Full Idea: If death is like a night of dreamless sleep it is an advantage, for such nights are very pleasant, and eternity would seem like a single night. | |
From: Socrates (reports of last days [c.399 BCE]), quoted by Plato - The Apology 40d | |
A reaction: Dreamless sleep is only pleasant if being awake is unpleasant. Very quiet days are only pleasant if the active days are horrible. A desire for a totally quiet life is absurd. |
2 | We should not even harm someone who harms us [Socrates] |
Full Idea: One should never return an injustice nor harm another human being no matter what one suffers at their hands. | |
From: Socrates (reports of last days [c.399 BCE]), quoted by Plato - Crito 49c | |
A reaction: Jesus of Nazareth was not the first person to make this suggestion. |
345 | A good man cannot be harmed, either in life or in death [Socrates] |
Full Idea: A good man cannot be harmed, either in life or in death. | |
From: Socrates (reports of last days [c.399 BCE]), quoted by Plato - The Apology 41d |
346 | One ought not to return a wrong or injury to any person, whatever the provocation [Socrates] |
Full Idea: One ought not to return a wrong or an injury to any person, whatever the provocation is. | |
From: Socrates (reports of last days [c.399 BCE]), quoted by Plato - Crito 49b | |
A reaction: The same as the essential moral teachings of Jesus (see Idea 6288) and Lao Tzu (Idea 6324). The big target is not to be corrupted by the evil of other people. |
341 | Wealth is good if it is accompanied by virtue [Socrates] |
Full Idea: Wealth does not bring about excellence, but excellence makes wealth and everything else good for men. | |
From: Socrates (reports of last days [c.399 BCE]), quoted by Plato - The Apology 30b |
347 | Will I stand up against the law, simply because I have been unjustly judged? [Socrates] |
Full Idea: Do I intend to destroy the laws, because the state wronged me by passing a faulty judgement at my trial? | |
From: Socrates (reports of last days [c.399 BCE]), quoted by Plato - Crito 50c |
6613 | The natural kinds are objects, processes and properties/relations [Ellis] |
Full Idea: There are three hierarchies of natural kinds: objects or substances (substantive universals), events or processes (dynamic universals), and properties or relations (tropic universals). | |
From: Brian Ellis (Katzav on limitations of dispositions [2005], 91) | |
A reaction: Most interesting here is the identifying of natural kinds with universals, making universals into the families of nature. Universals are high-level sets of natural kinds. To grasp universals you must see patterns, and infer the underlying order. |
6616 | Least action is not a causal law, but a 'global law', describing a global essence [Ellis] |
Full Idea: The principle of least action is not a causal law, but is what I call a 'global law', which describes the essence of the global kind, which every object in the universe necessarily instantiates. | |
From: Brian Ellis (Katzav on limitations of dispositions [2005]) | |
A reaction: As a fan of essentialism I find this persuasive. If I inherit part of my essence from being a mammal, I inherit other parts of my essence from being an object, and all objects would share that essence, so it would look like a 'law' for all objects. |
6615 | A species requires a genus, and its essence includes the essence of the genus [Ellis] |
Full Idea: A specific universal can exist only if the generic universal of which it is a species exists, but generic universals don't depend on species; …the essence of any genus is included in its species, but not conversely. | |
From: Brian Ellis (Katzav on limitations of dispositions [2005], 91) | |
A reaction: Thus the species 'electron' would be part of the genus 'lepton', or 'human' part of 'mammal'. The point of all this is to show how individual items connect up with the rest of the universe, giving rise to universal laws, such as Least Action. |
6614 | A hierarchy of natural kinds is elaborate ontology, but needed to explain natural laws [Ellis] |
Full Idea: The hierarchy of natural kinds proposed by essentialism may be more elaborate than is strictly required for purposes of ontology, but it is necessary to explain the necessity of the laws of nature, and the universal applicability of global principles. | |
From: Brian Ellis (Katzav on limitations of dispositions [2005], 91) | |
A reaction: I am all in favour of elaborating ontology in the name of best explanation. There seem, though, to be some remaining ontological questions at the point where the explanations of essentialism run out. |
6612 | Without general principles, we couldn't predict the behaviour of dispositional properties [Ellis] |
Full Idea: It is objected to dispositionalism that without the principle of least action, or some general principle of equal power, the specific dispositional properties of things could tell us very little about how these things would be disposed to behave. | |
From: Brian Ellis (Katzav on limitations of dispositions [2005], 90) | |
A reaction: Ellis attempts to meet this criticism, by placing dispositional properties within a hierarchy of broader properties. There remains a nagging doubt about how essentialism can account for space, time, order, and the existence of essences. |
338 | Socrates is accused of denying the gods, saying sun is stone and moon is earth [Socrates, by Plato] |
Full Idea: Socrates denies the gods, because he says the sun is stone and the moon is earth. | |
From: report of Socrates (reports of last days [c.399 BCE]) by Plato - The Apology 26d |
