In a deterministic universe it is determined whether the thief will

stop if someone yells at him. However, neither the person yelling nor
```the thief knows for sure whether he will stop or not.

```
What difference would it make to them if neither the person yelling nor the thief can control whether or not they are yelling or stealing?
```
It will make exactly whatever difference is determined (or random).

You're not getting my point. If you say that the boat doesn't exist, why would it matter if it has a hole in it or not?

I don't know whether or not a puddle in the gutter will dry out or not overnight, but why would that generate some sort of interest to me?

Furthermore, it

with a perfect model of his brain, due to the nature of classical
chaotic systems.

```
It doesn't matter because in a deterministic universe it would be impossible to care whether the thief would stop or not.
```
```
Unless it was determined that you would care, in which case it would impossible not to care. That's what deterministic means, things are *determined*.
```
```
Why would there be a such thing as "care" in a deterministic universe? I don't think it is defensible that it could. If *all things are determined* then there can be no "care".
```
```
Everything is determined does not entail that *you* can determine everything.
```
```
But it does entail that we cannot determine anything. That's my point, is that care can only arise out of the possibility of determining something ourselves, just as the idea of a game can only arise out of the possibility of participation. Without that possibility of direct participation, the whole ontological basis of "care" is nullified as "clouds" would be nullified in the absence of the possibility of atmosphere.
```
```
OK, but then you agree that the "universe" can be entirely deterministic, and determined (perhaps only in God eyes), and yet we have still free will, due to the fact that "we" cannot determine everything. this will be in general the case when we are confronted with machine as complex, or more complex than ourselves.
```
```
No, it doesn't make sense to me that there would be a highly valued qualia of free will (and highly charged qualia of responsibility) if our participation did not actually contribute causally in determining the universe.
```
```
But our participation do actually contribute, causally indeed, in determining the universe. It is real genuine high level causation, capable of reflecting our values and our deepest beliefs.
```

```
A free spectator in a deterministic machine can feel no responsibility or presence.

Not only a machine (the person supervening on a machine) can feel responsibility, but that person can be responsible.

I was watching a CGI cartoon this morning and was noticing that the sterility of the medium must be fought every step of the way by the animators to inject some warmth and character. The digital medium is not neutral, it is anesthetically biased. Because computation is devoid both of the gravity of realism
```
You betray a naive conception of computations.

and the vitality of animation, the CGI animator must compensate with low level visual distractions at all times - plugging the holes in the audience's experience with lots of clever details.

```
I am not talking about today's machine, but about what is Turing emulable in principle.
```
```
What is not Turing emulable in your theory. Don't answer with "sense", because the simplest theory of machine's sense makes them also non Turing emulable. The non Turing emulability of sense is not an argument against comp, it is a correct intuition that machine can have about themselves, when looking inward.
```
```
If you study computer science, you can understand that most attribute of machine are more complex notion than computation and Turing emulability. Machines are such that the whole can be far more complex and rich than any of the parts, or the disjoint union of the parts.
```
Negative assertions seems premature to me, here.

Mentally ill people don't have different brain *physics*.

```
Splitting hairs. Using English words in a nonsense order may technically be *English* but it is still a language problem.
```
If the brain
is deterministic in a well person it is deterministic in a mentally
```
ill person as well. The difference is that the mentally ill person may
```not be able to (deterministically) respond to certain situations in
```
the way a well person will (deterministically) respond to them. Judges
```are usually quite intelligent people and I expect that most of them
are aware that everything in the world must be either determined or
random, but they still make their judgements despite this.

```
No judge could make any judgment against a person if they really believed that everything must be determined or random. That would mean that their judgments would also be deterministic or random, so that they would not be a judge at all, but rather a pawn of "inevitable and necessary consequences of antecedent states of affairs."
```
Judgment is impossible under determinism.
```
```
Unless it's determined, in which case non-judgement is impossible.

You are confusing determinism with omnipotent magic.
