| 8836 | Must all justification be inferential? [Ginet] |
| Full Idea: The infinitist view of justification holds that every justification must be inferential: no other kind of justification is possible. | |
| From: Carl Ginet (Infinitism not solution to regress problem [2005], p.141) | |
| A reaction: This is the key question in discussing whether justification is foundational. I'm not sure whether 'inference' is the best word when something is evidence for something else. I am inclined to think that only propositions can be reasons. |
| 8837 | Inference cannot originate justification, it can only transfer it from premises to conclusion [Ginet] |
| Full Idea: Inference cannot originate justification, it can only transfer it from premises to conclusion. And so it cannot be that, if there actually occurs justification, it is all inferential. | |
| From: Carl Ginet (Infinitism not solution to regress problem [2005], p.148) | |
| A reaction: The idea that justification must have an 'origin' seems to beg the question. I take Klein's inifinitism to be a version of coherence, where the accumulation of good reasons adds up to justification. It is not purely inferential. |
| 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. |
