Claims about 'the Absolute' are not even verifiable in principle [Ayer on Bradley]
|
|
Full Idea:
Such a metaphysical pseudo-proposition as 'the Absolute enters into, but is itself incapable of, evolution and progress' (F.H.Bradley) is not even in principle verifiable.
|
|
From:
comment on F.H. Bradley (Appearance and Reality [1893]) by A.J. Ayer - Language,Truth and Logic Ch.1
|
|
A reaction:
One may jeer at the Verification Principle for either failing to be precise, or for failing to pass its own test, but Ayer still has a point here. When we drift off into sustained abstractions, we must keeping asking if we are still saying anything real.

In "if and only if" (iff), "if" expresses the sufficient condition, and "only if" the necessary condition [Engel]
|
|
Full Idea:
Necessary and sufficient conditions are usually expressed by "if and only if" (abbr. "iff"), where "if" is the sufficient condition, and "only if" is the necessary condition.
|
|
From:
Pascal Engel (Truth [2002], §1.1)
|
|
A reaction:
'I take my umbrella if and only if it is raining' (oh, and if I'm still alive). There may be other necessary conditions than the one specified. Oh, and I take it if my wife slips it into my car…

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.

Are truth-bearers propositions, or ideas/beliefs, or sentences/utterances? [Engel]
|
|
Full Idea:
The tradition of the Stoics and Frege says that truth-bearers are propositions, Descartes and the classical empiricist say they are ideas or beliefs, and Ockham and Quine say they are sentences or utterances.
|
|
From:
Pascal Engel (Truth [2002], §1.1)
|
|
A reaction:
I'm with propositions, which are unambiguous, can be expressed in a variety of ways, embody the 'logical form' of sentences, and could be physically embodied in brains (the language of thought?).

Internal relations are said to be intrinsic properties of two terms, and of the whole they compose [Bradley, by Russell]
|
|
Full Idea:
The doctrine of internal relations held that every relation between two terms expresses, primarily, intrinsic properties of the two terms and, in ultimate analysis, a property of the whole which the two compose.
|
|
From:
report of F.H. Bradley (Appearance and Reality [1893]) by Bertrand Russell - My Philosophical Development Ch.5
|
|
A reaction:
Russell's first big campaign was to reject this view, and his ontology from then on included relations among the catalogue of universals. The coherence theory of truth also gets thrown out at the same time. Russell seems right.

Relations must be linked to their qualities, but that implies an infinite regress of relations [Bradley]
|
|
Full Idea:
If a relation between qualities is to be something, then clearly we will now require a new connecting relation. The links are united by a link, and this link has two ends, which require a fresh link to connect them to the old.
|
|
From:
F.H. Bradley (Appearance and Reality [1893], p.28), quoted by Cynthia Macdonald - Varieties of Things Ch.6
|
|
A reaction:
That is: external relations generates an infinite regress, so relations must be internal. Russell launched his own philosophy with an attack on Bradley's idea. Personally I take how two things 'relate' to one another as one of the deepest of mysteries.

'Evidentialists' say, and 'voluntarists' deny, that we only believe on the basis of evidence [Engel]
|
|
Full Idea:
The 'evidentialists' (such as Locke and Hume) deny, and the 'voluntarists' (such as William James) affirm, that we ought to, or at least may, believe for other reasons than evidential epistemic reasons (e.g. for pragmatic reasons).
|
|
From:
Pascal Engel (Truth [2002], §5.2)
|
|
A reaction:
No need to be black-or-white here. Blatant evidence compels belief, but we may also come to believe by spotting a coherence, without additional evidence. We can also be in a state of trying to believe something. But see 4764.

British Idealists said reality is a single Mind which experiences itself [Bradley, by Grayling]
|
|
Full Idea:
The idealism of Green and Bradley, both of whom were much influenced by the German Idealists, espoused the thesis that the universe ultimately consists of a single Mind which, so to speak, experiences itself.
|
|
From:
report of F.H. Bradley (Appearance and Reality [1893]) by A.C. Grayling - Russell Ch.2
|
|
A reaction:
This looks now like the last (extreme) throw by the religious view of the world, which collapsed in the face of the empirical realism of Russell and Moore. It is all Kant's fault, for cutting us off from his 'noumenon'.

We cannot directly control our beliefs, but we can control the causes of our involuntary beliefs [Engel]
|
|
Full Idea:
Direct psychological voluntarism about beliefs seems to be false, but we can have an indirect voluntary control on many of our beliefs, by manipulating the states in us that are involuntary and which lead to certain beliefs.
|
|
From:
Pascal Engel (Truth [2002], §5.2)
|
|
A reaction:
Very nice! This points two ways - to scientific experiments, which can have compelling outcomes (see Fodor), and to brain-washing, and especially auto-brainwashing (only reading articles which support your favourites theories). What magazines do you take?

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.

Happiness is not satisfaction of desires, but fulfilment of values [Bradley, by Scruton]
|
|
Full Idea:
For Bradley, the happiness of the individual is not to be understood in terms of his desires and needs, but rather in terms of his values - which is to say, in terms of those of his desires which he incorporates into his self.
|
|
From:
report of F.H. Bradley (Ethical Studies [1876]) by Roger Scruton - Short History of Modern Philosophy Ch.16
|
|
A reaction:
Good. Bentham will reduce the values to a further set of desires, so that a value is a complex (second-level?) desire. I prefer to think of values as judgements, but I like Scruton's phrase of 'incorporating into his self'. Kant take note (Idea 1452).

Reality is one, because plurality implies relations, and they assert a superior unity [Bradley]
|
|
Full Idea:
Reality is one. It must be simple because plurality, taken as real, contradicts itself. Plurality implies relations, and, through its relations it unwillingly asserts always a superior unity.
|
|
From:
F.H. Bradley (Appearance and Reality [1893], p.519), quoted by A.C. Grayling - Russell Ch.2
|
|
A reaction:
This argument depends on a belief in 'internal' relations, which Russell famously attacked. If an internal feature of every separate item was its relation to other things, then I suppose Bradley would be right. But it isn't, and he isn't.
