The thought experiments refute your claim that the principle 'no effect can be greater than the sum of its causes' fails in the example of water boiling. As such, the principle still stands. I have apparently failed to convince you of it, but it has yet to be refuted. I can provide more supporting examples upon request.I don't know what you think you are getting out of this line. Your initial premise has been reduced to well-known conservation laws — SophistiCat
I am not sure if you are saying yes or no. Either the law of conservation of mass and energy applies in the case of the big bang, or it does not. If it does, then the big bang necessarily possessed all the mass and energy found in the universe today. If not, then not. While the laws of physics may change, logic does not.No, I am saying that it's more complicated than you suppose and can't be adequately summed up by a simple aphorism. — SophistiCat
You are correct that the argument is founded on these assumptions, but they also seem rather common sensical. As such, they are the prima facie and the onus of proof is on the other side.These assumptions seem to be completely unjustified — SophistiCat
I agree with this. Science presupposes logic, and math is the logic of numbers.Science couldn't get going without maths and the rules of inference, and the like - so maths is prior to the sciences. — Wayfarer
That's me. We cannot conceive a universe where 2+2≠4. Therefore math is part of eternal truth.there are always some mathematical Platonists, i.e. those who believe that number is real but not material. — Wayfarer
That is why I ask if the natural sciences can deal with anything that is not material, because it seems that all that can be touched, felt or measured is either matter or energy. This would make naturalism and materialism equivalent terms.What actually is meant by 'empirical' is simply 'something tangible' i.e. something that can be touched, felt, measured, either by the senses or by scientific instruments, which are extensions to the senses. — Wayfarer
At first glance, I see only two logical possibilities in that multiverse hypothesis:'multiverse' speculation - the idea that the Universe we know, is one of countless 'bubble universes' that never come into contact with one another. — Wayfarer
That's an interesting point. Here are thought experiments to show that the claims are not arbitrary:So the move here is to point to a transient property, such as "boiling," and say that it always existed in potentia, and needed only a suitable cause to be actualized. This clever get-out-of-jail clause can paper over any difficulty with properties that appear to be new in effects. But why not use the same move on every property? Well, then it would be hard to link back to the original idea, that of invariant property transfer from cause to effect. For that you have appealed to energy, matter and other more-or-less conserved quantities, chosen ad hoc for each particular case. — SophistiCat
I'm with you on that one: The undeniable order in the universe strongly points to an order-giver.But why didn't it simply culminate in wreckage, 'greater entropy'? Why did it give rise to the exquisite order of nature? 'Just happened' doesn't strike me as any kind of hypothesis. — Wayfarer
I wonder still if the definitions are not essentially saying the same thing in different ways. Aren't natural sciences dealing only with things that are empirical; and all that is empirical is material? Maybe math is the exception, but I can't think of another one.the referent of 'naturalism' is 'what is subject to study by the natural sciences', whereas materialism is the belief that only material objects and forces are real. — Wayfarer
It changes my argument drastically if we only consider material things, but we can try it out for fun anyways:What does the argument look like stated in those terms? — Srap Tasmaner
I think that indeed we can reduce the thesis "conservation of property" to "conservation of mass and energy" when it comes to the natural or material world.So does your thesis of "conservation of properties," if we're calling it that, come down to a restatement of the first law of thermodynamics (with a nod to the second), once you've reduced everything to matter and energy? — Srap Tasmaner
Information or knowledge is neither matter or energy, because it can be shared without being lost by the emitter. Thus information fits the "conservation of property" thesis in the sense that the receiver may not receive more than what is emitted, but it does not follow the laws of thermodynamics because the information is not merely transferred, but duplicated.You also mentioned genes, so there's an issue about information... — Srap Tasmaner
I don't understand your position. Are you denying that there is energy transfer from the fire to the water? If yes, then what is the causal relationship between the two, if any? If no, then what is wrong with my premise? That energy is the common property between the cause and the effect.The fire underneath the boiling pot has neither the energy nor the temperature of the boiling water. It also does not possess the property of boiling. — SophistiCat
Does it make my reasoning invalid?This does not mean that just because I can imagine a unicorn, that unicorns exist, but that the basic components of the unicorn (colours, shapes, sounds, ...) must exist. — Samuel Lacrampe
Yep. I stand corrected. Upon further thinking, I too don't actually believe that all that exists can be conceived. Thanks for finding the flaw in that reasoning.The first premise is, at best, a rather optimistic statement about our cognitive faculties. But, even if it happens to be true, I wouldn't take it as a metaphysical first principle: the world has no obligation to be comprehensible to the human intellect. And if you take it definitionally (possibility is conceivability) then you are trivializing your conclusion. — SophistiCat
The fire emits the energy received by the water to boil, and the "boiling" effect is just the combination of the energy (caused by the fire) and the potential of water molecules to boil (not caused by the fire). And we know the energy received cannot be more than the energy emitted, due to the first law of thermodynamics.A boiling pot, for instance: neither the fire under the pot nor the water prior to the onset of boiling have the property of boiling. — SophistiCat
Indeed. The fire has a property of being greater than 100C, which agrees with my point that the cause(s) may be greater or equal to the effect.For that matter, the fire that brings the water to a boil does not have the property of being at 100C. — SophistiCat
Still an incorrect causal relationship. The words have a physical property (say pixels on the screen), and a meaning. The meaning of the words is caused by you directly, and they are also a property of you because you can think (i.e. you meant what you wrote). You are not composed of pixels, but the direct cause of the pixels is the computer, which has the ability to create these pixels.I just caused that sentence to exist. It has the property of being composed of words; I am not composed of words. — Srap Tasmaner
This sounds like a self-contradiction: Do you (or Michael Dummett) have a means which would in principle decide the truth-value of that very statement? If not, then according to that statement, we do not have for it a notion of truth and falsity which would entitle us to say that it must be true or false.Unless we have a means which would in principle decide the truth-value of a given statement, we do not have for it a notion of truth and falsity which would entitle us to say that it must be true or false.
While I take your statement in consideration, I do not base truth on philosophers and their authority, but rather on philosophy. I trust you do the same.So you should at least be aware that there are philosophers who have qualms about drawing "logical" conclusions about matters we can in principle know nothing about. — Srap Tasmaner
In any case, your conclusion (that the cause must possess all properties of its effects) obviously does not follow. — SophistiCat
I tried to prove this here. Where do you see a flaw in the reasoning?But conservation of properties does not follow from this. — SophistiCat
I think this is logically provable: Once again, let's start with the self-evident principle that 'nothing can come from nothing'. Therefore the event 'a thing begins to exist' must come from something. And a thing cannot cause itself into existence, because to cause something, one must first exist, which is self-contradictory. Therefore everything that begins to exist requires an external cause for its existence."Everything that begins to exist requires a cause for its existence" is just a variation on the Principle of Sufficient Reason, which I don't think we are obligated to accept as a dogma. — SophistiCat
Very interesting. I will stay away from it because its complexity makes it hard to convince.I think someone, maybe Alvin Plantinga, has argued that if God is possible then he must exist--that his existence in some possible world would be necessary in that world, and that if he's necessary in that possible world then he's necessary in all of them, and therefore he exists. It was something like that. — Srap Tasmaner
I disagree. I will explain my same point (original here) in smaller steps: Using the law of noncontradiction, either a thing has a cause or not. This is true regardless if the thing is observable or not, because the law of noncontradiction is an absolute. If it does not have a cause, then it does not have a cause for its existence. But everything that begins to exist requires an external cause for its existence, and cannot cause itself into existence, because to cause something, one must first exist. Therefore if a thing has no cause, then it cannot begin to exist, therefore it must possess eternal existence.Not what I'm talking about. Bivalence is different. We do not have to accept that "has a cause" is either true or false of entities that are in principle unobservable. — Srap Tasmaner
Thanks bro. I hope this will not be seen as a fight between theists vs non-theists, but merely philosophers looking for truth.As an aside: I did some googling, and it looks like a lot of your ideas come from apologetics. I just want to commend you for coming here to test them out among people with different backgrounds and commitments. — Srap Tasmaner
Maybe I am misunderstanding what you are saying, or you are misunderstanding me, because I am with you, that we cannot say that 'everything has a cause', only that 'everything that we can observe (the natural universe) has a cause'.You know you just emptied the predicate "has a cause" of all content by extending it to everything, right? — Srap Tasmaner
But the law of non-contradiction is an absolute. "A is B" and "A is not B" are mutually exclusive. And this is true regardless of what A and B are.Some of us are going to balk at extending the principle of bivalence to propositions that, as you just told us, are in principle unverifiable. I might. — Srap Tasmaner
