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
While it may be hard to pronounce, the argument is really a simple syllogism in the form:Now if 'all that can exist' is 'anything that we can conceive', and 'anything that we can conceive' is 'anything that must exist', then 'all that can exist' is 'anything that must exist'. — Samuel Lacrampe
Actually, I don't think that 'everything has a cause'. Only that 'everything in the natural universe has a cause'. There is no need to extend the principle further than the data set that we can observe, which is only the natural universe.Your premise is that everything has a cause. — SophistiCat
Logically, either a thing has a cause or else it is an eternal being which has always existed, because everything that begins to exist requires a cause for its existence. It could be that eternal things exist in the natural universe but I cannot think of one off the top of my head.It is very much debatable that this is a self-evident truth or that we have no choice but adopt this a metaphysical axiom. — SophistiCat
Agreed. Common usage or common sense determines the prima facie or default position, but is not a proof.What's important is (a) not to assume that what carries the authority of common usage is true — Srap Tasmaner
This is not the causal relationship between the hammer and the nail. The only effect to the nail caused by the hammer is the energy from the hammer received to the nail. And we know that the energy received is not greater than the original energy due to the second law of thermodynamics, which states that no energy can be created.If that seems too clever, here's another: striking the nail with a hammer causes the nail to enter the board. The nail entering the board has the property of wood being displaced by steel; the hammer striking the nail does not. — Srap Tasmaner
I agree. But my intent was not to prove God's existence, merely to answer the question of 'how do people go from the first cause to God?' This is my answer for believers.Begging the question by assuming that there is a God and that the Bible is his words. — Michael
Mmm... You may have a point here... But I'll attempt to refute it anyways.And thirdly, it wouldn't follow that the first cause is that which nothing greater can exist, only that the first cause is that which nothing greater does exist. — Michael
Just nitpicking: Your definition makes the cause 'equal', not necessarily 'greater'.We define a "greater cause" to be a cause which possesses all the properties that its correlated effects possess. — Srap Tasmaner
Can you show me why?No effect has a property not possessed by its cause.
This is patently false, as a moment's reflection would show. — Srap Tasmaner
That's okay if you have not heard of God being defined in that way before. You just need to 'buy' into the definition for us to have a meaningful argument; because we cannot argue if we are not on a common ground when it comes to the terms used. We could technically replace the word 'God', with the word 'X', and this would not change the validity of the syllogism, as long as we agree on the meaning of the terms.Premise 1 is a claim about language use among I don't know what community of speakers, which doesn't seem like it would suit what seems to be a metaphysical argument. There's also something there about this community's imaginative capacity, and I don't know what to do with that that either. I don't know how to verify any of those claims, or what I would have if I did. Even if Premise 1 is true in some specified sense, what good is it? — Srap Tasmaner
I see your point. We just need to differentiate between the epistemological order and metaphysical order of the two words. Epistemologically, we humans first experience the natural world and then may call some things supernatural when these don't behave as per the laws of our natural world. Metaphysically however, the supernatural is the cause of the natural, and thus existed prior to it. Sure, you can switch the labels around if desired, as long as the definitions are clear to everyone. For practical purposes though, I would stick to the conventional definitions.The structure AND meaning of the word, "supernatural", shows that it stems from the world, "natural", which means that it is dependent upon the existence of the natural, which means that the natural came first and then the supernatural. — Harry Hindu
It is. But we can bridge that gap a couple of ways:The problem is that it's quite a leap to go from "the first cause doesn't behave according to the laws of physics" to "the first cause is God". — Michael
You are contradicting yourself, because you agreed earlier that "everything in the natural universe has a cause". The first cause, by definition, has a causal relationship, but no cause.If the universe was the effect of some cause, then that cause would be "natural" too, as there would be a causal relationship between the cause and the effect. — Harry Hindu
Because if the universe has a beginning, then there must be a first thing. The only logical alternative is no beginning. But finiteness is a simpler hypothesis than infinity, and so, as per Occam's Razor, it becomes the prima facie until proven otherwise.Why must there be a "first" natural thing? Why isn't it natural all the way down? — Harry Hindu
