| 3695 | Philosophy is a priori if it is anything [Bonjour] |
| Full Idea: My conviction is that philosophy is a priori if it is anything. | |
| From: Laurence Bonjour (In Defence of Pure Reason [1998], Pref) | |
| A reaction: How about knowledge of a posteriori necessities, such as the length of a metre, known by observation of the standard metre in Paris? |
| 3651 | Perceiving necessary connections is the essence of reasoning [Bonjour] |
| Full Idea: If one never in fact grasps any necessary connections between anything, it is hard to see what reasoning could possible amount to. | |
| From: Laurence Bonjour (In Defence of Pure Reason [1998], §4.3) |
| 3700 | Coherence can't be validated by appeal to coherence [Bonjour] |
| Full Idea: The epistemic authority of coherence cannot itself be established by appeal to coherence. | |
| From: Laurence Bonjour (In Defence of Pure Reason [1998], §3.7 n50) | |
| A reaction: The standard approach amongs modern philosophers (following, I think, Kripke) is to insist on 'intuition' as basic, despite all its problems. I have no better suggestion. |
| 3697 | The concept of possibility is prior to that of necessity [Bonjour] |
| Full Idea: While necessity and possibility are interdefinable concepts, it is the idea of a possible world or situation which is intuitively primary. | |
| From: Laurence Bonjour (In Defence of Pure Reason [1998], §1.3) |
| 3704 | Moderate rationalists believe in fallible a priori justification [Bonjour] |
| Full Idea: Moderate rationalism preserves a priori justification, but rejects the idea that it is infallible. | |
| From: Laurence Bonjour (In Defence of Pure Reason [1998], §4.1) |
| 3707 | Our rules of thought can only be judged by pure rational insight [Bonjour] |
| Full Idea: Criteria or rules do not somehow apply to themselves. They must be judged by the sort of rational insight or intuition that the rationalist is advocating. | |
| From: Laurence Bonjour (In Defence of Pure Reason [1998], §5.2) |
| 3696 | A priori justification requires understanding but no experience [Bonjour] |
| Full Idea: A proposition will count as being justified a priori as long as no appeal to experience is needed for the proposition to be justified - once it is understood. | |
| From: Laurence Bonjour (In Defence of Pure Reason [1998], §1.2) | |
| A reaction: Could you 'understand' that a square cannot be circular without appeal to experience? I'm losing faith in the pure a priori. |
| 3703 | You can't explain away a priori justification as analyticity, and you can't totally give it up [Bonjour] |
| Full Idea: Moderate empiricists try unsuccessfully to explain a priori justification by means of analyticity, and radical empiricist attempts to dispense with a priori justification end in nearly total scepticism. | |
| From: Laurence Bonjour (In Defence of Pure Reason [1998], §4.1) | |
| A reaction: My working theory is neither of the above. Because we can abstract from the physical world, we can directly see/experience generalised (and even necessary) truths about it. |
| 3706 | A priori justification can vary in degree [Bonjour] |
| Full Idea: A priori justification can vary in degree. | |
| From: Laurence Bonjour (In Defence of Pure Reason [1998], §4.5) | |
| A reaction: This idea, which I trace back at least to Russell, seems to me one of breakthrough ideas in modern thought. It means that a priori knowledge can be reconnected with a posteriori knowledge. |
| 3699 | The induction problem blocks any attempted proof of physical statements [Bonjour] |
| Full Idea: The attempt to prove physical statements on the basis of sensory evidence is defeated by the problem of induction. | |
| From: Laurence Bonjour (In Defence of Pure Reason [1998], §3.6) | |
| A reaction: This sounds like a logician's use of the word 'prove', which would be a pretty forlorn hope. Insofar as experience proves anything, fully sensing a chair proves its existence. |
| 3701 | Externalist theories of justification don't require believers to have reasons for their beliefs [Bonjour] |
| Full Idea: An externalist theory of epistemic justification or warrant need not involve the possession by the believer of anything like a reason for thinking that their belief is true. | |
| From: Laurence Bonjour (In Defence of Pure Reason [1998], §3.7) | |
| A reaction: That is the problem with externalism. If the believer does not have a reason, then why would they believe? Externalists are interesting on justification, but daft about belief. Why do I believe I know something, when I can't recall how I learnt it? |
| 3702 | Externalism means we have no reason to believe, which is strong scepticism [Bonjour] |
| Full Idea: If externalism is the final story, we have no reason to think that any of our beliefs are true, which amounts to a very strong and intuitively implausible version of scepticism. | |
| From: Laurence Bonjour (In Defence of Pure Reason [1998], §3.7) | |
| A reaction: A very good point. I may, like a cat, know many things, with good external support, but as soon as I ask sceptical questions, I sink without trace if I lack internal reasons. |
| 3709 | Induction must go beyond the evidence, in order to explain why the evidence occurred [Bonjour] |
| Full Idea: Inductive explanations must be conceived of as something stronger than mere Humean constant conjunction; …anything less than this will not explain why the inductive evidence occurred in the first place. | |
| From: Laurence Bonjour (In Defence of Pure Reason [1998], §7.7) |
| 3444 | If actions are not caused by other events, and are not causeless, they must be caused by the person [Chisholm] |
| Full Idea: If the action is not caused by some other event, and it is not causeless, this leaves the possibility that it is caused by something else instead, and this something can only be the agent, the man. | |
| From: Roderick Chisholm (Human Freedom and the Self [1964], p.28) |
| 3446 | For Hobbes (but not for Kant) a person's actions can be deduced from their desires and beliefs [Chisholm] |
| Full Idea: According to Hobbes, if we fully know what a man desires and believes, and we know the state of his physical stimuli, we may logically deduce what he will try to do. But Kant says no such statements can ever imply what a man will do. | |
| From: Roderick Chisholm (Human Freedom and the Self [1964], p.32) |
| 9268 | If free will miraculously interrupts causation, animals might do that; why would we want to do it? [Frankfurt on Chisholm] |
| Full Idea: Chisholm holds the quaint doctrine that human freedom entails an absence of causal determination; a free action is a miracle. This gives no basis for doubting that animals have such freedom; and why would we care whether we can interrupt the causal order? | |
| From: comment on Roderick Chisholm (Human Freedom and the Self [1964]) by Harry G. Frankfurt - Freedom of the Will and concept of a person §IV | |
| A reaction: [compressed] Chisholm is the spokesman for 'agent causation', Frankfurt for freedom as second-level volitions. I'm with Frankfurt. The belief in 'agents' and 'free will' may sound plausible, until the proposal is spelled out in causal terms. |
| 3708 | All thought represents either properties or indexicals [Bonjour] |
| Full Idea: I assume that the contents of thought can be accounted for by appeal to just two general sorts of ingredient - properties (including relations) and indexicals. | |
| From: Laurence Bonjour (In Defence of Pure Reason [1998], §6.7) | |
| A reaction: I don't accept that relations are a type of properties. Since he does not include objects or substances, I take it that he considers objects to be bundles of properties. |
| 19216 | Propositions (such as 'that dog is barking') only exist if their items exist [Williamson] |
| Full Idea: A proposition about an item exists only if that item exists... how could something be the proposition that that dog is barking in circumstances in which that dog does not exist? | |
| From: Timothy Williamson (Necessary Existents [2002], p.240), quoted by Trenton Merricks - Propositions | |
| A reaction: This is a view of propositions I can't make sense of. If I'm under an illusion that there is a dog barking nearby, when there isn't one, can I not say 'that dog is barking'? If I haven't expressed a proposition, what have I done? |
| 3698 | Indeterminacy of translation is actually indeterminacy of meaning and belief [Bonjour] |
| Full Idea: The thesis of the indeterminacy of translation would be better described as the thesis of the indeterminacy of meaning and belief. | |
| From: Laurence Bonjour (In Defence of Pure Reason [1998], §3.5) | |
| A reaction: Not necessarily. It is not incoherent to believe that the target people have a coherent and stable system of meaning and belief, but finding its translation indeterminate because it is holistic, and rooted in a way of life. |
| 3442 | Responsibility seems to conflict with events being either caused or not caused [Chisholm] |
| Full Idea: The free will problem is that humans seem to be responsible, but this seems to conflict with the idea that every event is caused by some other event, and it also conflicts with the view that the action is not caused at all. | |
| From: Roderick Chisholm (Human Freedom and the Self [1964], p.24) |
| 3443 | Desires may rule us, but are we responsible for our desires? [Chisholm] |
| Full Idea: If a flood of desires causes a weak-willed man to give in to temptation, …the question now becomes, is he responsible for the beliefs and desires he happens to have? | |
| From: Roderick Chisholm (Human Freedom and the Self [1964], p.25) |
| 3445 | Causation among objects relates either events or states [Chisholm] |
| Full Idea: Between natural objects we may say that causation is a relation between events or states of affairs. | |
| From: Roderick Chisholm (Human Freedom and the Self [1964], p.28) |
