Philosophy may never find foundations, and may undermine our lives in the process [Fogelin]
|
|
Full Idea:
Not only is traditional philosophy incapable of discovering the foundations it seeks, but the philosophical enterprise may itself dislodge the contingent, de facto supports that our daily life depends upon.
|
|
From:
Robert Fogelin (Walking the Tightrope of Reason [2003], Ch.2)
|
|
A reaction:
In the end Fogelin is not so pessimistic, but he is worried by the concern of philosophers with paradox and contradiction. I don't remotely consider this a reason to reject philosophy, but it might be a reason to keep it sealed off from daily life.

One view says objectivity is making a successful claim which captures the facts [Reiss/Sprenger]
|
|
Full Idea:
One conception of objectivity is that the facts are 'out there', and it is the task of scientists to discover, analyze and sytematize them. 'Objective' is a success word: if a claim is objective, it successfully captures some feature of the world.
|
|
From:
Reiss,J/Spreger,J (Scientific Objectivity [2014], 2)
|
|
A reaction:
This seems to describe truth, rather than objectivity. You can establish accurate facts by subjective means. You can be fairly objective but miss the facts. Objectivity is a mode of thought, not a link to reality.
|

|
An absolute scientific picture of reality must not involve sense experience, which is perspectival [Reiss/Sprenger]
|
|
Full Idea:
Sense experience is necessarily perspectival, so to the extent to which scientific theories are to track the absolute conception [of reality], they must describe a world different from sense experience.
|
|
From:
Reiss,J/Spreger,J (Scientific Objectivity [2014], 2.3)
|
|
A reaction:
This is a beautifully simple and interesting point. Even when you are looking at a tree, to grasp its full reality you probably need to close your eyes (which is bad news for artists).

Topic and application involve values, but can evidence and theory choice avoid them? [Reiss/Sprenger]
|
|
Full Idea:
There may be values involved in the choice of a research problem, the gathering of evidence, the acceptance of a theory, and the application of results. ...The first and fourth do involve values, but what of the second and third?
|
|
From:
Reiss,J/Spreger,J (Scientific Objectivity [2014], 3.1)
|
|
A reaction:
[compressed] My own view is that the danger of hidden distorting values has to be recognised, but it is then possible, by honest self-criticism, to reduce them to near zero. Sociological enquiry is different, of course.

The Value-Free Ideal in science avoids contextual values, but embraces epistemic values [Reiss/Sprenger]
|
|
Full Idea:
According to the Value-Free Ideal, scientific objectivity is characterised by absence of contextual values and by exclusive commitment to epistemic values in scientific reasoning.
|
|
From:
Reiss,J/Spreger,J (Scientific Objectivity [2014], 3.1)
|
|
A reaction:
This seems appealing, because it concedes that we cannot be value-free, without suggesting that we are unavoidably swamped by values. The obvious question is whether the two types of value can be sharply distinguished.
|
22362
|
Value-free science needs impartial evaluation, theories asserting facts, and right motivation [Reiss/Sprenger]
|
|
Full Idea:
Three components of value-free science are Impartiality (appraising theories only by epistemic scientific standards), Neutrality (the theories make no value statements), and Autonomy (the theory is motivated only by science).
|
|
From:
Reiss,J/Spreger,J (Scientific Objectivity [2014], 3.3)
|
|
A reaction:
[They are summarising Hugh Lacey, 1999, 2002] I'm not sure why the third criterion matters, if the first two are met. If a tobacco company commissions research on cigarettes, that doesn't necessarily make the findings false or prejudiced.

Thermometers depend on the substance used, and none of them are perfect [Reiss/Sprenger]
|
|
Full Idea:
Thermometers assume the length of the fluid or gas is a function of temperature, and different substances yield different results. It was decided that different thermometers using the same substance should match, and air was the best, but not perfect.
|
|
From:
Reiss,J/Spreger,J (Scientific Objectivity [2014], 4.1)
|
|
A reaction:
[summarising Hasok Chang's research] This is a salutary warning that instruments do not necessarily solve the problem of objectivity, though thermometers do seem to be impersonal, and offer relative accuracy (i.e. ranking temperatures). Cf breathalysers.

There are several logics, none of which will ever derive falsehoods from truth [Lewis,CI]
|
|
Full Idea:
The fact is that there are several logics, markedly different, each self-consistent in its own terms and such that whoever, using it, avoids false premises, will never reach a false conclusion.
|
|
From:
C.I. Lewis (A Pragmatic Conception of the A Priori [1923], p.366)
|
|
A reaction:
As the man who invented modal logic in five different versions, he speaks with some authority. Logicians now debate which version is the best, so how could that be decided? You could avoid false conclusions by never reasoning at all.

Excluded middle is just our preference for a simplified dichotomy in experience [Lewis,CI]
|
|
Full Idea:
The law of excluded middle formulates our decision that whatever is not designated by a certain term shall be designated by its negative. It declares our purpose to make a complete dichotomy of experience, ..which is only our penchant for simplicity.
|
|
From:
C.I. Lewis (A Pragmatic Conception of the A Priori [1923], p.365)
|
|
A reaction:
I find this view quite appealing. 'Look, it's either F or it isn't!' is a dogmatic attitude which irritates a lot of people, and appears to be dispensible. Intuitionists in mathematics dispense with the principle, and vagueness threatens it.
|

|
We can maintain a priori principles come what may, but we can also change them [Lewis,CI]
|
|
Full Idea:
The a priori contains principles which can be maintained in the face of all experience, representing the initiative of the mind. But they are subject to alteration on pragmatic grounds, if expanding experience shows their intellectual infelicity.
|
|
From:
C.I. Lewis (A Pragmatic Conception of the A Priori [1923], p.373)
|
|
A reaction:
[compressed] This simply IS Quine's famous 'web of belief' picture, showing how firmly Quine is in the pragmatist tradition. Lewis treats a priori principles as a pragmatic toolkit, which can be refined to be more effective. Not implausible...

My view is 'circumspect rationalism' - that only our intellect can comprehend the world [Fogelin]
|
|
Full Idea:
My own view might be called 'circumspect rationalism' - the view that our intellectual faculties provide our only means for comprehending the world in which we find oruselves.
|
|
From:
Robert Fogelin (Walking the Tightrope of Reason [2003], Ch.3)
|
|
A reaction:
He needs to say more than that to offer a theory, but I like the label, and it fits the modern revival of rationalism, with which I sympathise, and which rests, I think, on Russell's point that self-evidence comes in degrees, not as all-or-nothing truth.

We rely on memory for empirical beliefs because they mutually support one another [Lewis,CI]
|
|
Full Idea:
When the whole range of empirical beliefs is taken into account, all of them more or less dependent on memorial knowledge, we find that those which are most credible can be assured by their mutual support, or 'congruence'.
|
|
From:
C.I. Lewis (An Analysis of Knowledge and Valuation [1946], 334), quoted by Erik J. Olsson - Against Coherence 3.1
|
|
A reaction:
Lewis may be over-confident about this, and is duly attacked by Olson, but it seems to me roughly correct. How do you assess whether some unusual element in your memory was a dream or a real experience?

If anything is to be probable, then something must be certain [Lewis,CI]
|
|
Full Idea:
If anything is to be probable, then something must be certain.
|
|
From:
C.I. Lewis (An Analysis of Knowledge and Valuation [1946], 186), quoted by Robert Fogelin - Walking the Tightrope of Reason Intro
|
|
A reaction:
Lewis makes this comment when facing infinite regress problems. It is a very nice slogan for foundationalism, which embodies the slippery slope view. Personally I feel the emotional pull of foundations, but acknowledge the very strong doubts about them.

For coherentists, circularity is acceptable if the circle is large, rich and coherent [Fogelin]
|
|
Full Idea:
Coherentists argue that if the circle of justifications is big enough, rich enough, coherent enough, and so on, then there is nothing wrong circularity.
|
|
From:
Robert Fogelin (Walking the Tightrope of Reason [2003], Ch.4)
|
|
A reaction:
There must always be something wrong with circularity, and no god would put up with it, but we might have to. Of course, two pieces of evidence might be unconnected, such as an equation and an observation.

Congruents assertions increase the probability of each individual assertion in the set [Lewis,CI]
|
|
Full Idea:
A set of statements, or a set of supposed facts asserted, will be said to be congruent if and only if they are so related that the antecedent probability of any one of them will be increased if the remainder of the set can be assumed as given premises.
|
|
From:
C.I. Lewis (An Analysis of Knowledge and Valuation [1946], 338), quoted by Erik J. Olsson - Against Coherence 2.2
|
|
A reaction:
This thesis is vigorously attacked by Erik Olson, who works through the probability calculations. There seems an obvious problem without that. How else do you assess 'congruence', other than by evidence of mutual strengthening?

Scepticism is cartesian (sceptical scenarios), or Humean (future), or Pyrrhonian (suspend belief) [Fogelin]
|
|
Full Idea:
The three forms of scepticism are cartesian, Humean and Pyrrhonian. The first challenges belief by inventing sceptical scenarios; the second doubts the future; the third aims to suspend belief.
|
|
From:
Robert Fogelin (Walking the Tightrope of Reason [2003], Ch.4)
|
|
A reaction:
A standard distinction is made between methodological and global scepticism. The former seems to be Cartesian, and the latter Pyrrhonian. The interest here is see Hume placed in a distinctive category, because of his views on induction.
|

|
Scepticism deals in remote possibilities that are ineliminable and set the standard very high [Fogelin]
|
|
Full Idea:
Sceptical scenarios deal in wildly remote defeating possibilities, so that the level of scrutiny becomes unrestrictedly high, and they also usually deal with defeators that are in principle ineliminable.
|
|
From:
Robert Fogelin (Walking the Tightrope of Reason [2003], Ch.4)
|
|
A reaction:
The question of how high we 'set the bar' seems to me central to epistemology. There is clearly an element of social negotiation involved, centring on what is appropriate. If, though, scepticism is 'ineliminable', we must face up to that.

The 'experimenter's regress' says success needs reliability, which is only tested by success [Reiss/Sprenger]
|
|
Full Idea:
The 'experimenter's regress' says that to know whether a result is correct, one needs to know whether the apparatus is reliable. But one doesn't know whether the apparatus is reliable unless one knows that it produces correct results ...and so on.
|
|
From:
Reiss,J/Spreger,J (Scientific Objectivity [2014], 2.3)
|
|
A reaction:
[H. Collins (1985), a sociologist] I take this to be a case of the triumphant discovery of a vicious circle which destroys all knowledge turning out to be a benign circle. We build up a coherent relationship between reliable results and good apparatus.

Extension is the class of things, intension is the correct definition of the thing, and intension determines extension [Lewis,CI]
|
|
Full Idea:
"The denotation or extension of a term is the class of all actual or existent things which the term correctly applies to or names; the connotation or intension of a term is delimited by any correct definition of it." ..And intension determines extension.
|
|
From:
C.I. Lewis (An Analysis of Knowledge and Valuation [1946]), quoted by Stephen P. Schwartz - Intro to Naming,Necessity and Natural Kinds §II
|
|
A reaction:
The last part is one of the big ideas in philosophy of language, which was rejected by Putnam and co. If you were to reverse the slogan, though, (to extension determines intension) how would you identify the members of the extension?

The word 'beautiful', when deprived of context, is nearly contentless [Fogelin]
|
|
Full Idea:
Like the word 'good', the word 'beautiful', when deprived of contextual support, is nearly contentless.
|
|
From:
Robert Fogelin (Walking the Tightrope of Reason [2003], Ch.6)
|
|
A reaction:
If I say with, for example, Oscar Wilde that beauty is the highest ideal in life, this doesn't strike me as contentless, but I still sympathise with Fogelin's notion that beauty is rooted in particulars.

Deterrence, prevention, rehabilitation and retribution can come into conflict in punishments [Fogelin]
|
|
Full Idea:
The purposes of punishment include deterrence, prevention, rehabilitation, and retribution, but they don't always sit well together. Deterrence is best served by making prisons miserable places, but this may run counter to rehabilitation.
|
|
From:
Robert Fogelin (Walking the Tightrope of Reason [2003], Ch.2)
|
|
A reaction:
It seems to most educated people that retribution should be pushed far down the list if we are to be civilised (see Idea 1659), and yet personal revenge for a small act of aggression seems basic, normal and acceptable. We dream of rehabilitation.

Science seeks classification which will discover laws, essences, and predictions [Lewis,CI]
|
|
Full Idea:
The scientific search is for such classification as will make it possible to correlate appearance and behaviour, to discover law, to penetrate to the "essential nature" of things in order that behaviour may become predictable.
|
|
From:
C.I. Lewis (A Pragmatic Conception of the A Priori [1923], p.368)
|
|
A reaction:
Modern scientific essentialists no longer invoke scare quotes, and I think we should talk of the search for the 'mechanisms' which explain behaviour, but Lewis seems to have been sixty years ahead of his time.
