So let me get this straight. Your using logic to provide evidence against logics infallibility?
If logic is fallible, then our ability to determine truth, and speak meaningfully, breaks down.
I was wondering whether someone was going to hit me up on this. But I do think it’s taking my argument far above and beyond what I intended (perhaps by my own fault). I am not suggesting that logic is too untrustworthy for use in constructing any philosophical conclusions whatsoever. I am simply suggesting that, where logic either contradicts itself or a widely accepted observation, it might not be wise to construct conclusions with 100% confidence based on logic alone. Especially in cases where logic contradicts itself.
Consider this. Do you believe in free will, even though it seemingly cannot logically exist? If so, then you’re effectively supporting my suggestion.
First of all, just because many people accept it, does not mean its true.
I did think I made that fairly clear? Why else would I have gone to such trouble elaborating on the calibre of those who do support the Copenhagen interpretation?
Secondly, Quantum events work at the quantum level of reality, that is why its called quantum. In this case, it is not logically possible that a cat can be both alive and dead.
The scenario I refer to was proposed by Erwin Schroedinger in 1935 as a direct consequence of the Copenhagen interpretation of quantum mechanics. Considering that this is the bloke who originally developed the wavefunction and a true pioneer of quantum mechanics, were he alive, I would be unlikely to argue with him.
Give the thought experiment a read, if you haven’t already.
Also, as you conveniently put, I agree that it is not
logically possible for cat to be both alive and dead at once. But not that it is impossible, at least from a strictly physical standpoint. I am not suggesting that it is definitely possible either, I myself am fairly undecided on the Copenhagen interpretation.
*For good reason. And they don’t have to reject quantum physics either! *
They have to reject the Copenhagen interpretation…
I didn’t really make a distinction between determinism and being governed by fixed physical rules.
Probably my fault. I interpreted wasmit’s use of the phrase that way and assumed you would do the same.
When you say that determinism has been disproved, I presume you mean that even knowing in full detail the state of a given system at any particular point in time would not allow you to determine its future state.
Very close but not quite. I mean this: “knowing in full detail the state of a given system at a particularly point in time does not imply that the state of the system at a later point in time can be determined
with 100% accuracy.” It’s a statistical game, and the uncertainty in the state of the system increases as time goes by.
Even quantum mechanics, though, has its own rules.
Yes, but they are not deterministic. I am fairly certain wasmit was referring to causality in his/her OP, hence why I brought quantum mechanics into the picture in the first place.
Traditional Catholic philosophical thinking about the body and soul isn’t really dualistic in its application even though it posits the existence of both matter and spirit. The human soul, though immaterial and thus not extended in space, is nevertheless thought to be the animating principle for every part of the human body–not just the brain. And further, the union between body and soul is considered to be so intimate that we are one entity, not two. Body and soul can be separated only by doing violence to our existence–i.e., by death, and the soul survives (as not a complete human being) only because of its immateriality. It has no parts to come apart or decompose.
And here obviously is a subject I am not so educated in. But it remains one I definitely would like to be. Thankyou for your (name removed by moderator)ut
*(Off topic, but it just occurred to me that if that is the case, what does it say about our predictions of climate change, the projections of which are based on imperfect attempts at computer modeling?)
When you are looking for an average, overall change in a system, your observations can be gathered with far more certainty. For example, in a gas, it is very very difficult to predict the distribution of the gas particles in a period of time, even without taking into account their quantum behaviour. But collective properties can be fairly accurately obtained; such as pressure, volume and temperature. It is the same with quantum mechanics. Consider a system comprised of say, a basketball. This basketball is comprised of billions of particles ungoing quantum behaviour, but the average position of those particles (to us, the position of the basketball) can be fairly accurately obtained. When dealing with a system as vast and complex as the Earth and its atmosphere, and collective properties as vast as the average surface temperature of the Earth, the effect of quantum mechanics is basically nil.
Is that making sense or is it all just dribble?
As to climate change’s validity, I am not really educated enough to comment. I’ve heard both sides of the story, and whilst my head is swaying towards the “it’s a load of ****” side of the argument, I am happy to treat the situation as if the human contribution to climate change is significant. Simply because we have much more to lose if we don’t believe in climate change and are wrong. Besides, I’d say making the world greener is a step in the right direction anyway. It makes sense to save on electricity and so forth, even if it does nothing else but save you money.
