2. Reason / A. Nature of Reason / 6. Coherence
Why should we prefer coherent beliefs? [Klein,P]
     Full Idea: A key question for a coherentist is, why should he or she adopt a coherent set of beliefs rather than an incoherent set?
     From: Peter Klein (Infinitism solution to regress problem [2005], 'Step 1')
     A reaction: The point of the question is that the coherentist may have to revert to other criteria in answering it. One could equally ask, why should I believe in tables just because I vividly experience them? Or, why believe 2+2=4, just because it is obvious?
13. Knowledge Criteria / A. Justification Problems / 2. Justification Challenges / a. Agrippa's trilemma
Infinitism avoids a regress, circularity or arbitrariness, by saying warrant just increases [Klein,P]
     Full Idea: Infinitism can solve the regress problem, because it endorses a warrant-emergent form of reasoning in which warrant increases as the series of reasons lengthens. The theory can avoid both circularity and arbitrariness.
     From: Peter Klein (Infinitism solution to regress problem [2005], 'Step 2')
     A reaction: It nicely avoids arbitrariness by offering a reason for absolutely every belief. I think the way to go may to combine individual Infinitism with a social account of where to set the bar of acceptable justification.
13. Knowledge Criteria / B. Internal Justification / 4. Foundationalism / e. Pro-foundations
If justification is endless, no link in the chain is ultimately justified [Ginet on Klein,P]
     Full Idea: An endless chain of inferential justifications can never ultimately explain why any link in the chain is justified.
     From: comment on Peter Klein (Infinitism solution to regress problem [2005]) by Carl Ginet - Infinitism not solution to regress problem p.148
     A reaction: This strikes me as a mere yearning for foundations. I don't see sense-experience or the natural light of human reason (or the word of God, for that matter) as in any way 'ultimate'. It's all evidence to be evaluated.
13. Knowledge Criteria / B. Internal Justification / 5. Coherentism / a. Coherence as justification
Reasons acquire warrant through being part of a lengthening series [Klein,P]
     Full Idea: The infinitist holds that finding a reason, and then another reason for that reason, places it at the beginning of a series where each gains warrant as part of the series. ..Rational credibility increases as the series lengthens.
     From: Peter Klein (Infinitism solution to regress problem [2005], p.137)
     A reaction: A striking problem here for Klein is the status of the first reason, prior to it being supported by a series. Surprisingly, it seems that it would not yet be a justification. Coherence accounts have the same problem, if coherence is the only criterion.
14. Science / D. Explanation / 2. Types of Explanation / e. Lawlike explanations
Generalisations must be invariant to explain anything [Leuridan]
     Full Idea: A generalisation is explanatory if and only if it is invariant.
     From: Bert Leuridan (Can Mechanisms Replace Laws of Nature? [2010], §4)
     A reaction: [He cites Jim Woodward 2003] I dislike the idea that generalisations and regularities explain anything at all, but this rule sounds like a bare minimum for being taken seriously in the space of explanations.
14. Science / D. Explanation / 2. Types of Explanation / h. Explanations by function
Biological functions are explained by disposition, or by causal role [Leuridan]
     Full Idea: The main alternative to the dispositional theory of biological functions (which confer a survival-enhancing propensity) is the etiological theory (effects are functions if they play a role in the causal history of that very component).
     From: Bert Leuridan (Can Mechanisms Replace Laws of Nature? [2010], §3)
     A reaction: [Bigelow/Pargetter 1987 for the first, Mitchell 2003 for the second] The second one sounds a bit circular, but on the whole a I prefer causal explanations to dispositional explanations.
14. Science / D. Explanation / 2. Types of Explanation / i. Explanations by mechanism
Mechanisms must produce macro-level regularities, but that needs micro-level regularities [Leuridan]
     Full Idea: Nothing can count as a mechanism unless it produces some macro-level regular behaviour. To produce macro-level regular behaviour, it has to rely on micro-level regularities.
     From: Bert Leuridan (Can Mechanisms Replace Laws of Nature? [2010], §5)
     A reaction: This is the core of Leuridan's argument that regularities are more basic than mechanisms. It doesn't follow, though, that the more basic a thing is the more explanatory work it can do. I say mechanisms explain more than low-level regularities do.
Mechanisms can't explain on their own, as their models rest on pragmatic regularities [Leuridan]
     Full Idea: To model a mechanism one must incorporate pragmatic laws. ...As valuable as the concept of mechanism and mechanistic explanation are, they cannot replace regularities nor undermine their relevance for scientific explanation.
     From: Bert Leuridan (Can Mechanisms Replace Laws of Nature? [2010], §1)
     A reaction: [See Idea 12786 for 'pragmatic laws'] I just don't see how the observation of a regularity is any sort of explanation. I just take a regularity to be something interesting which needs to be explained.
We can show that regularities and pragmatic laws are more basic than mechanisms [Leuridan]
     Full Idea: Summary: mechanisms depend on regularities, there may be regularities without mechanisms, models of mechanisms must incorporate pragmatic laws, and pragmatic laws do not depend epistemologically on mechanistic models.
     From: Bert Leuridan (Can Mechanisms Replace Laws of Nature? [2010], §1)
     A reaction: See Idea 14382 for 'pragmatic' laws. I'm quite keen on mechanisms, so this is an arrow close to the heart, but at this point I say that my ultimate allegiance is to powers, not to mechanisms.
Mechanisms are ontologically dependent on regularities [Leuridan]
     Full Idea: Mechanisms are ontologically dependent on the existence of regularities.
     From: Bert Leuridan (Can Mechanisms Replace Laws of Nature? [2010], §3)
     A reaction: This seems to be the Humean rearguard action in favour of the regularity account of laws. Wrong, but a nice paper. This point shows why only powers (despite their vagueness!) are the only candidate for the bottom level of explanation.
14. Science / D. Explanation / 3. Best Explanation / b. Ultimate explanation
There is nothing wrong with an infinite regress of mechanisms and regularities [Leuridan]
     Full Idea: I see nothing metaphysically wrong in an infinite ontological regress of mechanisms and regularities.
     From: Bert Leuridan (Can Mechanisms Replace Laws of Nature? [2010], §5)
     A reaction: This is a pretty unusual view, and I can't accept it. My revulsion at this regress is precisely the reason why I believe in powers, as the bottom level of explanation.
21. Aesthetics / C. Artistic Issues / 7. Art and Morality
Beauty motivates morality, by harmonising feeling and reason [Schiller, by Pinkard]
     Full Idea: On Schiller's view, only beauty could shape or evince the necessary harmony between sensibility and reason (between inclination and duty) which provides the crucial motivation for the moral life.
     From: report of Friedrich Schiller (works [1794]) by Terry Pinkard - German Philosophy 1760-1860 06
     A reaction: Maybe. Reason should probably be drawn towards feelings which seem inspiring.
25. Social Practice / A. Freedoms / 5. Freedom of lifestyle
Schiller speaks obsessively of freedom throughout his works [Schiller, by Berlin]
     Full Idea: Schiller constantly speaks of spiritual freedom: freedom of reason, the kingdom of freedom, our free self, inner freedom, freedom of mind, moral freedom, the free intelligence - a very favourite phrase - holy freedom, the impregnable citadel of freedom.
     From: report of Friedrich Schiller (works [1794]) by Isaiah Berlin - The Roots of Romanticism
     A reaction: Kant's philosophy and his Kingdom of Ends are an obvious source for this, but I trace the sentiment back to 'Freeborn John' Lilburne during the English Civil War. The English, thanks to Voltaire, embodied freedom in the Enlightenment.
26. Natural Theory / A. Speculations on Nature / 3. Natural Function
Rather than dispositions, functions may be the element that brought a thing into existence [Leuridan]
     Full Idea: The dispositional theory of biological functions is not unquestioned. The main alternative is the etiological theory: a component's effect is a function of that component if it has played an essential role in the causal history of its existence.
     From: Bert Leuridan (Can Mechanisms Replace Laws of Nature? [2010], §3)
     A reaction: [He cites S.D. Mitchell 2003] Presumably this account is meant to fit into a theory of evolution in biology. The obvious problem is where something comes into existence for one reason, and then acquires a new function (such as piano-playing).
26. Natural Theory / D. Laws of Nature / 3. Laws and Generalities
Pragmatic laws allow prediction and explanation, to the extent that reality is stable [Leuridan]
     Full Idea: A generalization is a 'pragmatic law' if it allows of prediction, explanation and manipulation, even if it fails to satisfy the traditional criteria. To this end, it should describe a stable regularity, but not necessarily a universal and necessary one.
     From: Bert Leuridan (Can Mechanisms Replace Laws of Nature? [2010], §1)
     A reaction: I am tempted to say of this that all laws are pragmatic, given that it is rather hard to know whether reality is stable. The universal laws consist of saying that IF reality stays stable in certain ways, certain outcomes will ensue necessarily.
26. Natural Theory / D. Laws of Nature / 4. Regularities / a. Regularity theory
Strict regularities are rarely discovered in life sciences [Leuridan]
     Full Idea: Strict regularities are rarely if ever discovered in the life sciences.
     From: Bert Leuridan (Can Mechanisms Replace Laws of Nature? [2010], §2)
     A reaction: This is elementary once it is pointed out, but too much philosophy have science has aimed at the model provided by the equations of fundamental physics. Science is a broad church, to employ an entertaining metaphor.
26. Natural Theory / D. Laws of Nature / 11. Against Laws of Nature
A 'law of nature' is just a regularity, not some entity that causes the regularity [Leuridan]
     Full Idea: By 'law of nature' or 'natural law' I mean a generalization describing a regularity, not some metaphysical entity that produces or is responsible for that regularity.
     From: Bert Leuridan (Can Mechanisms Replace Laws of Nature? [2010], §1 n1)
     A reaction: I take the second version to be a relic of a religious world view, and having no place in a naturalistic metaphysic. The regularity view is then the only player in the field, and the question is, can we do more? Can't we explain regularities?
