By the way, atheism has zero connection to evolutionary theory. — Terrapin Station
Back this up with a mathematical demonstration then. — Metaphysician Undercover
Another problem with science is that it says that two identical things will always act in the same way. This is an assumption. Two things are at least in different places, which can affect how they act. — Gregory
That one ball stops having kinetic energy, and the other one starts, does not mean that kinetic energy was transferred. — Metaphysician Undercover
First, we cannot say that the ball "is" kinetic energy, because a ball is more than just that, and the fact that it stops moving and has no more kinetic energy, in your example indicates that it is more than just kinetic energy. — Metaphysician Undercover
After the first ball strikes the second ball, the first ball no longer has kinetic energy, and the second ball has kinetic energy. So one ball looses kinetic energy, and another ball gains kinetic energy. — Metaphysician Undercover
By what principle do you say that this is a "transfer"? One object looses a property and another gains a similar property, why would this be a transfer of property? — Metaphysician Undercover
Do you observe the property coming off of the one and going into the other? — Metaphysician Undercover
If it is true that two solid objects cannot occupy the same space, how does this premise validate your claim that one object transfers a property to another? — Metaphysician Undercover
What we observe is that one object ceases to be in motion, and the other starts to be in motion. We do not see any transfer of motion. — Metaphysician Undercover
When you understand a ball as consisting of many parts, molecules, rather than as a mass with a centre of gravity, you'll see that all the kinetic energy of the one ball must be transformed into potential energy before that potential energy can act as a force to accelerate the second ball. — Metaphysician Undercover
So there is no transferral of kinetic energy, there is a deceleration of the first ball, as its kinetic energy is transformed to potential energy, and an acceleration of the second ball, as that potential energy acts to create kinetic energy in the second ball. Potential energy acts as a medium between the two instances of kinetic energy, therefore there is no transferral of kinetic energy, only two instances of kinetic energy, with potential energy separating the two. — Metaphysician Undercover
Sure. But first, take your foot out of your mouth. — Banno
But with billiard balls, you aren't feeling them, so the second ball might have moved without the first hitting it. — Gregory
So science is subjective!!! Your attempt to salvage it is not working. — Gregory
This is a lie worthy of Trump. You provided the link to the Google search. Look at the Google Search. It does not support your contention that Newton wrote a law of cause and effect. — Banno
It's pretty astonishing that someone with pretences to philosophical reasoning can present such an argument. — Banno
Some small number of folk do call Newton;s third Law the Law of Cause and Effect. It's certainly not common, and it is also misleading.
SO it seems to me that unfortunately your research is misguided. — Banno
I don't wholly buy into the Principle of Sufficient Reason either. — ChatteringMonkey
I simply ask you what you directly observe. Answer pending.... — tim wood
No it's not, that's a Newtonian way of speaking about it. There is no attraction, mass curves spacetime, and the curve of spacetime determines how masses move. Singling out causes and effects to describe a proces where everything influences everthing else seems to only complicate the matter unnecessarily. — ChatteringMonkey
This is clear from the fact that gravity is a force, and it is not an object in motion. — Metaphysician Undercover
OK, then when someone like Newton declares a law, what is it based on? — Metaphysician Undercover
It's a question. Given that you claim we can directly observe causation, you should be able to tell me what the actual cause is, in physical terms. — Echarmion
Can you point out to me what physical laws make this a physical necessity? — Echarmion
It could be kept alive by machinery. That's not difficult to imagine given we can stop people's hearts for surgery. — Echarmion
So, if there are multiple, which one is the cause? Are all together the cause? — Echarmion
No, there's a very big difference here. Force is equal to mass times acceleration. And momentum is equal to mass times velocity. "Kinetic energy" was developed from Leibniz' "vis viva" (living force), which was expressed as mass time velocity squared. This was later modified in the concept of "kinetic energy" such that kinetic energy is half of the vis viva — Metaphysician Undercover
Despite your claim that I am thinking wrong, you clearly have this backward. The "physical law" is an inductive conclusion, produced from descriptions of natural occurrences. Any "necessity" which is apprehended is a logical necessity dependent on acceptance of the inductive law. — Metaphysician Undercover
There is no necessary relationship between the physical law and any "natural law". — Metaphysician Undercover
I think you slightly misunderstand the point of the example. It's about why cutting of the head can be labeled a "cause" even though it's only one element among many of the system. I turned your examples around to show that your "cause" is not sufficient. — Echarmion
So it must be the moving brick approaching the window. It must be that the brick, in some instant, while on a certain vector through spacetime, is just about to occupy the same space and time as the window, on a different vector through spacetime. But that is a description of a state, followed by another state, where various particles are now on different vectors. We might call the transition from one state to another an "interaction", but where, precisely, is the cause? Is the entire state of the universe that cause, and the entire next state the effect? — Echarmion
Hume only made a sceptical argument about Causation, namely that (on a macro-level) we don't see anything like a mechanism or law of Causation, which was inferred by others at the time. For Causation to be true metaphysically it has to be true on a more fundamental level too, or what would 'metaphysical' mean otherwise? — ChatteringMonkey
On a classical scale means on the surface, emergent... that is not fundamentally or metaphysically. — ChatteringMonkey
Edit: The point is not that Hume took a modern physics point of view, but that he was sceptical of people inferring something they had no evidence for. And as it turns out modern physics seems to justify his scepticism. — ChatteringMonkey
I don't think causes (and effects) are the best vocabulary to use here, the curvature of spacetime doesn't exactly 'cause' attraction... Edit: ... and although some of the math stayed the same, the whole paradigm has changed. — ChatteringMonkey
Cause and effect are not directly observable. One might be able to observe a sequence of events, and then to claim that one is the cause, another the effect; but that claim, while perhaps guided by observation, is not something one can see. — Banno
Newton did not write a specific law of cause and effect; in particular, the law "To every action there is always opposed an equal action" is not a law of cause and effect. — Banno
Notice that we conclude deductively that a force acted, by applying Newton's first law as a premise. We do not observe that a force acted. — Metaphysician Undercover
Great! What colour are they? DImensions - large? Small? Rough? Smooth? Opaque? Translucent? Anything at all? — tim wood
Are you ready to discuss Newton's laws without substituting "force", and address directly what Newton meant by this term? — Metaphysician Undercover
Hume is also the better scientist because he takes what the world does. — TheWillowOfDarkness
How many times do we have to test bread before we know infallibly what bread is? — Gregory
Science has worked so far, but so far we haven't seen the argument that it will continue too. — Gregory
You'd go to a scientist. What Hume is saying is not relevant to science, per se, so to interpret him as a lousy scientist is to misunderstand the point. — Wayfarer
...because it remains a possibility that the world, and all of what we know in it, remains a consistent illusion. There's nothing a scientist would be able to say about that, as science starts with the presumption that it is not. — Wayfarer
How many heads does a caveman have to cut off before he knows about this "law"? — Gregory
Newton is like yang and Hume is like yin. You need both in life. Hume is more mystical you might say, but it is pure rational argumentation. Those who dismiss Hume are like the Thomists who think they understand matter so well as to "know" that it needs a spiritual being to sustain it. As for Kant, Hegel said that he made the Enlightenment into philosophical methods — Gregory
Hume is questioning the nature of knowledge, the steps by which we arrive at understanding, whereas you're simply accepting the apparent veracity of the senses in the matter. — Wayfarer
All of what you say about Hume's argument about causation is directly comparable. You're simply appealing to common sense -saying, in effect, that 'obviously a causes b because we can see it'. Then you wonder how the subject of philosophy could be so daft as to fall for such an obvious fallacy. — Wayfarer
All we sense is matter. Hume says we are so far from understanding matter that it get even in the way of understanding motion! — Gregory
And that's why I would probably not read your paper - it would seem to be arguing thatHume misunderstood something Newton did not say. — Banno
