Hintikka I 77
Measuring/Wittgenstein/Hintikka: Suppose you use a pole to find out whether the bottom of a river is sandy or muddy. This pole cannot be used in the same way to find out how the pole itself is made. On the other hand, it is easily possible to use the pole to find out whether it can be used to reach the ground at all.

"...when I apply a scale to a spatial object, I apply all scale lines at the same time."
I 216 ff
Comparability/World/Picture/Measuring/Verification/Wittgenstein/Hintikka: One cannot compare a picture with reality if one cannot measure it against it. You have to be able to put the sentence onto reality.
>
Reality.

Measuring/Wittgenstein: The scale must always be in the same room as the measured thing.
Only the sentences of a physicalistic language can be compared with facts and therefore also represent them.

Measuring/Wittgenstein: Sentence: e.g. "apply the scale three times to G, and you will get the height of G". Then the existence of G and also that of the scale belongs to the sentence. The height of G, on the other hand, is not part of the sentence.

Def Time/Wittgenstein: is what is measured with a clock. >
Time.
If we know several measurement methods that do not contradict each other, we do not require a specific method to explain these words. But test methods give different meanings to the expression "have the same color" .
II 236
Measuring/Wittgenstein: "Greenwich's scale is actually one foot long" there is no point in saying that. It is a definition. Example: Originial Meter.
II 238
Measuring/Scale/flexible/Wittgenstein: For example, we could also call all the values read at different temperatures the real length. To the objection that "I like it and I don't like it" which is not a case to which "contradiction" applies, corresponds the objection that a scale is useless unless it is rigid. However, in some cases elasticity may be desired.

...besides, Russell's equal signs can be eliminated, and in this case the equations cannot be written down at all.
Difference:
Measuring: e.g. numerical equality of classes or
Calculating: e.g. equal number of roots of a 4th degree equation: one is a measurement,
the other a calculation. >
Calculus.
Is there an experiment to determine if two classes have the same number? This may or may not be the case for classes that cannot be overlooked.
II 355
It is a damaging prejudice to believe that we are dealing with an experiment when using strokes.
II 333
Pattern/Meter/prototype metre/Scale/Measurement/Wittgenstein: the pattern does not belong to the application, but to the language - the existence of the metre measure does not guarantee that there is something that is one metre long. Setting the scale is a decision, not a discovery.
II 367
Measuring/Wittgenstein: it is also when I am asked whether two pieces of wood are of equal length, and then I put them on top of each other and answer yes.
You might ask if I know that nothing happened to them when they were measured. The answer is that talking about equality is no longer relevant if any method of establishing equality is rejected!
II 368
If you claim the equality of lengths, it means that you say something about the method of investigation.
>
Method, >
Comparisons.
II 437
Root/Construction/Wittgenstein: For example, the diagonal is turned to the number line. Without the construction √2 is not the length. This length is not an approximation. It has nothing to do with measuring by a meter.

Prototype metre/Wittgenstein/Flor: precisely because it is a paradigm - a means of creating the language game, it is not something that is produced in the language game.
>
Language game.

Measuring/Wittgenstein/Schulte: one is to describe the measurement method, another is to find the results.
But what we call "measuring" is determined by a certain consistency of measurement results.
VI 165
Scale/Measuring/Tractatus/Schulte: the image is linked to reality: it reaches to it. It is like a measure of reality. Only the outermost points of the scale lines touch the object.
Thesis: a system of sentences is applied to reality like a yardstick. But I apply all scale lines at the same time.
