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.
|

|
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.

Metaphysical possibility is discovered empirically, and is contrained by nature [Edgington]
|
|
Full Idea:
Metaphysical necessity derives from distinguishing things which can happen and things which can't, in virtue of their nature, which we discover empirically: the metaphysically possible, I claim, is constrained by the laws of nature.
|
|
From:
Dorothy Edgington (Two Kinds of Possibility [2004], §I)
|
|
A reaction:
She claims that Kripke is sympathetic to this. Personally I like the idea that natural necessity is metaphysically necessary (see 'Scientific Essentialism'), but the other way round comes as a bit of a surprise. I will think about it.

Logical necessity is epistemic necessity, which is the old notion of a priori [Edgington, by McFetridge]
|
|
Full Idea:
Edgington's position is that logical necessity is an epistemic notion: epistemic necessity which, she claims, is the old notion of the a priori. Like Kripke, she thinks this is two-way independent of metaphysical necessity.
|
|
From:
report of Dorothy Edgington (Epistemic and Metaphysical Possibility [1985]) by Ian McFetridge - Logical Necessity: Some Issues §1
|
|
A reaction:
[her paper was unpublished] She hence thinks an argument can be logically valid, while metaphysically its conclusion may not follow. Dubious, though I think I favour the view that logical necessity is underwritten by metaphysical necessity.

Truth-functional possibilities include the irrelevant, which is a mistake [Edgington]
|
|
Full Idea:
How likely is a fair die landing on an even number to land six? My approach is, assume an even number, so three possibilities, one a six, so 'one third'; the truth-functional approach is it's true if it is not-even or six, so 'two-thirds'.
|
|
From:
Dorothy Edgington (Do Conditionals Have Truth Conditions? [1986], 3)
|
|
A reaction:
The point is that in the truth-functional approach, if the die lands not-even, then the conditional comes out as true, when she says it should be irrelevant. She seems to be right about this.
|

|
It is a mistake to think that conditionals are statements about how the world is [Edgington]
|
|
Full Idea:
The mistake philosophers have made, in trying to understand the conditional, is to assume that its function is to make a statement about how the world is (or how other possible worlds are related to it), true or false, as the case may be.
|
|
From:
Dorothy Edgington (Do Conditionals Have Truth Conditions? [1986], 1)
|
|
A reaction:
'If pigs could fly we would never catch them' may not be about the world, but 'if you press this switch the light comes on' seems to be. Actually even the first one is about the world. I've an inkling that Edgington is wrong about this. Powers!

Are conditionals truth-functional - do the truth values of A and B determine the truth value of 'If A, B'? [Edgington]
|
|
Full Idea:
Are conditionals truth-functional - do the truth values of A and B determine the truth value of 'If A, B'? Are they non-truth-functional, like 'because' or 'before'? Do the values of A and B, in some cases, leave open the value of 'If A,B'?
|
|
From:
Dorothy Edgington (Conditionals [2001], 17.1)
|
|
A reaction:
I would say they are not truth-functional, because the 'if' asserts some further dependency relation that goes beyond the truth or falsity of A and B. Logical ifs, causal ifs, psychological ifs... The material conditional ⊃ is truth-functional.
|

|
'If A,B' must entail ¬(A & ¬B); otherwise we could have A true, B false, and If A,B true, invalidating modus ponens [Edgington]
|
|
Full Idea:
If it were possible to have A true, B false, and If A,B true, it would be unsafe to infer B from A and If A,B: modus ponens would thus be invalid. Hence 'If A,B' must entail ¬(A & ¬B).
|
|
From:
Dorothy Edgington (Conditionals [2001], 17.1)
|
|
A reaction:
This is a firm defence of part of the truth-functional view of conditionals, and seems unassailable. The other parts of the truth table are open to question, though, if A is false, or they are both true.

Non-truth-functionalist say 'If A,B' is false if A is T and B is F, but deny that is always true for TT,FT and FF [Edgington]
|
|
Full Idea:
Non-truth-functional accounts agree that 'If A,B' is false when A is true and B is false; and that it is sometimes true for the other three combinations of truth-values; but they deny that the conditional is always true in each of these three cases.
|
|
From:
Dorothy Edgington (Conditionals (Stanf) [2006], 2.1)
|
|
A reaction:
Truth-functional connectives like 'and' and 'or' don't add any truth-conditions to the values of the propositions, but 'If...then' seems to assert a relationship that goes beyond its component propositions, so non-truth-functionalists are right.
|

|
Conditionals express what would be the outcome, given some supposition [Edgington]
|
|
Full Idea:
It is often necessary to suppose (or assume) that some epistemic possibility is true, and to consider what else would be the case, or would be likely to be the case, given this supposition. The conditional expresses the outcome of such thought processes.
|
|
From:
Dorothy Edgington (Do Conditionals Have Truth Conditions? [1986], 1)
|
|
A reaction:
This is the basic Edgington view. It seems to involve an active thought process, and imagination, rather than being the static semantic relations offered by possible worlds analyses. True conditionals state relationships in the world.
|

|
Truth-functionalists support some conditionals which we assert, but should not actually believe [Edgington]
|
|
Full Idea:
There are compounds of conditionals which we confidently assert and accept which, by the lights of the truth-functionalist, we do not have reason to believe true, such as 'If it broke if it was dropped, it was fragile', when it is NOT dropped.
|
|
From:
Dorothy Edgington (Conditionals (Stanf) [2006], 2.5)
|
|
A reaction:
[The example is from Gibbard 1981] The fact that it wasn't dropped only negates the nested antecedent, not the whole antecedent. I suppose it also wasn't broken, and both negations seem to be required.
|

|
Does 'If A,B' say something different in each context, because of the possibiites there? [Edgington]
|
|
Full Idea:
A pragmatic constraint might say that as different possibilities are live in different conversational settings, a different proposition may be expressed by 'If A,B' in different conversational settings.
|
|
From:
Dorothy Edgington (Conditionals (Stanf) [2006], 4.1)
|
|
A reaction:
Edgington says that it is only the truth of the proposition, not its content, which changes with context. I'm not so sure. 'If Hitler finds out, we are in trouble' says different things in 1914 and 1944.

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.
