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.

Equivalence relations are reflexive, symmetric and transitive, and classify similar objects [Lipschutz]
|
|
Full Idea:
A relation R on a non-empty set S is an equivalence relation if it is reflexive (for each member a, aRa), symmetric (if aRb, then bRa), and transitive (aRb and bRc, so aRc). It tries to classify objects that are in some way 'alike'.
|
|
From:
Seymour Lipschutz (Set Theory and related topics (2nd ed) [1998], 3.9)
|
|
A reaction:
So this is an attempt to formalise the common sense notion of seeing that two things have something in common. Presumably a 'way' of being alike is going to be a property or a part

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.

Fields can be 'scalar', or 'vector', or 'tensor', or 'spinor' [Baggott]
|
|
Full Idea:
Fields can be 'scalar', with no particular direction (pointing, but not pushing or pulling); or 'vector', with a direction (like magnetism, or Newtonian gravity); or 'tensor' (needing further parameters); or 'spinor' (depending on spin orientation).
|
|
From:
Jim Baggott (Farewell to Reality: fairytale physics [2013], 2 'Quantum')
|
|
A reaction:
[compressed] So the question is, why do they differ? What is it in the nature of each field the result in a distinctive directional feature?

Thermodynamics sees nature as a continuous flow of energy, as radiation and as substance [Baggott]
|
|
Full Idea:
Thermodynamics reinforced a vision of nature as one of harmonious flow. Energy, which could be neither created nor destroyed, flowed continuously between radiation and material substance, in themselves unbroken continua.
|
|
From:
Jim Baggott (The Quantum Story: 40 moments [2011], 01)
|
|
A reaction:
Interestingly, Einstein's Special Relativity e = mc2 seems to endorse this view, by equation energy and mass. I've always wanted to know what energy is, but no one seems to know.
