4.1 The Paradox
Note:Tttttttttttt

Yellow highlight | Location: 2,200
You have been fitted with an unobtrusive torture device, which will be attached to you for the rest of your life.

At setting 1, the device applies a very slight electric current to the pain center in your brain.
Note:CHE FA

Yellow highlight | Location: 2,203
At setting 2, it applies a very slightly higher electric current. And so

However, by the time you get up to setting 1,000, you are in severe pain.

If you turn it up by one, you will be given $10,000. You can never turn the dial down

Should you turn the dial up on day one?
Note:LA DOMANDA (RIPETUTA)

Yellow highlight | Location: 2,209
“If I turn the dial up just one setting, I won’t even notice the difference. However, I will have an additional $10,000, which is a significant and very noticeable benefit.
Note:COME RAGIONO

Yellow highlight | Location: 2,212
the same reasoning applies every day.
Note:Cccccccccc

Yellow highlight | Location: 2,212
at the end of 1,000 days, you have made $10 million, and you are condemned to spend the rest of your life in agony.
Note:FINALE

How is it possible that by making the correct choice at every stage,

This case might also be taken to illustrate how the “better than” relation can be intransitive.

for each n, it is better to go to setting n+1
Note:INFATTI

Yellow highlight | Location: 2,223
You like potato chips, but you do not want to become overweight. You pick up chip #1 and consider whether to eat it. If you eat it, you will experience a noticeable pleasure attributable to that particular chip.
Note:UN CASO CONCRETO

Yellow highlight | Location: 2,231
it would be nice to have a solution that explains why this scenario does not truly exhibit intransitivity of betterness

4.2 Quinn’s Solution
Note:Ttttttttttttt

Yellow highlight | Location: 2,234
Warren Quinn proposes that the self-torturer should try focusing his attention on some proper subset of all the settings of the device –
Note:DA 0 a 200 DA 200 a 400...TRA I SUB C È TRANSITIVITÀ MA ALL INTERNO

Preference Consistency: If one has a choice between A and B, and one rationally prefers A to B, it is rational to choose A.
Note:NOZIONE ELEMENTARE

Yellow highlight | Location: 2,253
Strategy Consistency:
Note:MA C È OL ALTERNATIVA

Yellow highlight | Location: 2,255
Quinn holds that we should reject Preference Consistency because, in the case of the self-torturer on day 201, Preference Consistency conflicts with Strategy Consistency.
Note:TESI QUINN

Yellow highlight | Location: 2,259
I think Preference Consistency is a self-evident principle

4.3.1 In Defense of Undetectable Changes
Note:Tttttttttt

Yellow highlight | Location: 2,267
it is possible for there to be changes in a person’s conscious experience too small to be introspectively detected.
Note:ASSUNTO

Yellow highlight | Location: 2,268
there could be two pains so similar to each other that
Note:Cccccccccccc

Yellow highlight | Location: 2,269
Something analogous is certainly true of observable physical properties.
Note:IL PIÙ CALDO?…IL PIÙ GRANDE?… IMPOSSIBILE DIRE

Yellow highlight | Location: 2,271
nevertheless, one might in fact be larger,
Note:Ccccccccccccc

Yellow highlight | Location: 2,273
one might claim, if two pain sensations feel to us the same, then ipso facto they are exactly the same.
Note:MA I SENTIMENTI NN SONO OGGETTI

Yellow highlight | Location: 2,276
This argument cannot be correct;
Note:È NECESSARIO RESPINGERE QS OBIEZIONE

Yellow highlight | Location: 2,309
self-torturer scenario just entails that there can be undetectable but real differences in one’s experiences.

Note that we are not here positing unconscious pains.

4.3.2 Indeterminacy
Note:Ttttttttttttt

Yellow highlight | Location: 2,315
“But the measure of the self-torturer’s discomfort,” says Quinn , “is indeterminate.
Note:LA RISPOSTA DI QUINN A HUEMER

Yellow highlight | Location: 2,321
He is proposing that there are pains that fail to have any specific intensity.
Note:TRADUZIONE

Yellow highlight | Location: 2,326
His view would have to be that pains have intensity, but they do not have any specific intensity.
Note:ALTRA VERSIONE

Yellow highlight | Location: 2,342
I think he is saying that for any given pain, there are certain intensities such that it is neither true nor false that the pain has them.
Note:RITRADUZIONE DI QUINN

Yellow highlight | Location: 2,345
This is a contradiction. To say that x neither has nor fails to have q, where q is some property,
Note:VIOLATA LA BIVALENZA

Yellow highlight | Location: 2,349
Similarly, to say that it is neither true nor false that x has q is to say that “x has q” isn’t true and “x has q” isn’t false.
Note:OVVERO

4.3.3 In Defense of an Optimal Setting
Note:Tttttttttttttttt

Yellow highlight | Location: 2,365
for each n, the self-torturer should assume that turning up the dial from n to n+1 is one thousandth as bad (in terms of pain) as turning the dial from 0 to 1000.
Note:LA POSIZIONE PIÙ COERENTE

Yellow highlight | Location: 2,370
Unlike pleasure and pain, money has diminishing marginal value .

4.3.4 Detectable and Undetectable Values
Note:Ttttttttttttttt

Yellow highlight | Location: 2,427
I am not at all convinced that the benefit of $10,000 remains significant or even noticeable as one’s wealth expands up to $10 million.

4.3.5 Advantages of This Solution
Note:Ttttttttttt

Yellow highlight | Location: 2,447
My treatment, though faithful to the factual (non-evaluative) stipulations of the scenario, does not involve any intransitivity, either of the better-than relation, or of rational preferences.
Note:PRIMO VANTAGGIO

Yellow highlight | Location: 2,453
My treatment of the case does not violate classical logic.
Note:SECONDO VANTAGGIO....NN IMPLICA INDETERMINAZIONE

Yellow highlight | Location: 2,455
My treatment of the case maintains standard principles of decision theory, including the axiom that, when given a choice between two options, one of which is rationally preferred to the other, one ought to take the preferred option.
Note:TERZO

Yellow highlight | Location: 2,461
there can be unnoticeable facts about the qualitative character of conscious mental states.
