It was not clear if the OP was looking for “presuppositions” that only applied to pre-1900 physics — Questioner
Differences of degree within these qualitative wholes are quantitative. — Joshs
Galileo, like Kepler, was inevitably led to the doctrine of primary and secondary qualities…Galileo makes the clear distinction between that in the world which is absolute, objective, immutable, and mathematical; and that which is relative, subjective, fluctuating, and sensible. The former is the realm of knowledge, divine and human; the latter is the realm of opinion and illusion.
The Copernican astronomy and the achievements of the two new sciences must break us of the natural assumption that sensed objects are the real or mathematical objects. They betray certain qualities, which, handled by mathematical rules, lead us to a knowledge of the true object, and these are the real or primary qualities, such as number, figure, magnitude, position, and motion, which cannot by any exertion of our powers be separated from bodies— qualities which also can be wholly expressed mathematically. The reality of the universe is geometrical; the only ultimate characteristics of nature are those in terms of which certain mathematical knowledge becomes possible.
All other qualities, and these are often far more prominent to the senses, are secondary, subordinate effects of the primary. Of the utmost moment was Galileo’s further assertion that these secondary qualities are subjective.

Scientific inquiry presupposes a mind-independent, law-governed reality and the reliability of our cognitive and instrumental access to it, assumptions that science itself cannot justify without circularity. — Tom Storm
You disagree with the generally accepted use of the words "phase" and 'form" in science? — Questioner
It describes the state of physics knowledge in 1900. — Questioner
"Numbers" related to science are expressed in units, and measure some quantitative property of the object under investigation. It is not correct to refer to "phases" of energy. When we are talking about energy, we talk about "the form of the energy." — Questioner
in late 1900 - Planck introduced the concept of "quanta" - that energy could be emitted in discrete packages
in 1905 - Einstein's Theory of Relativity merged space and time to spacetime - and measurements of them became relative to an observer's motion and gravity — Questioner
So, in 1900, Newtonian physics still prevailed. Determinism was the prevailing belief. They lived in a deterministic universe, where the future behavior of systems could be predicted if their initial conditions were known with sufficient accuracy. Energy was viewed as a continuous wave-like phenomenon. Maxwell's electromagnetism provided a nearly complete description of the universe. And they held to the existence of a ubiquitous, rigid, massless medium they called “aether” – and light and electromagnetic waves propagated through it. — Questioner
but science is not based on "suppositions." — Questioner
For something to have mathematical characteristics, it must have a qualitative identity which persists over time. — Joshs
Numeric iteration (differences in degree) implies sameness in kind. — Joshs
"The real world in which man lives is a world of atoms, equipped with none but mathematical characteristics and moving accord — T Clark
Science can only deal with what our senses reveal...with what is measurable and quantifiable. There are other less 'hard' areas of enquiry such as psychology, anthropology, sociology, ethology that require thinking in terms of purpose and reasons rather than or as well as mechanical causal models. So I think it depends on what you mean by "epistemology". — Janus
A scientist doesn't even need to think of what is being investigated as physical. They can simply "shut up and calculate" or they could think everything is ultimately mind and still do science perfectly as adequately as they do thinking everything is physical. — Janus
I can't see why one would need to be a metaphysical materialist in order to do science. Scince can only deal with what is given by the senses―that is its methodology. — Janus
The question that jumps out at me is: are the mathematical laws themselves physical, and, if so, how? I don’t expect an answer to that, as there isn’t one, so far as I know. But it makes a point about an inherent contradiction in physicalism. — Wayfarer
I'm not arguing for physicalism but against the idea that it is inherently contradictory. It can be argued that what we think of as laws are simply the ways physical things behave on the macro level based on what is ultimately stochastic at the micro-physical level. — Janus
And Wayfarer can of course elucidate, but I took him to mean that a "law" isn't something made of physical items. — J
Physical systems instantiate regularities;
scientific laws articulate those regularities in mathematical form. The laws themselves are not physical objects but ideal structures, grasped through intellectual acts of abstraction and measurement.
To treat laws as physical is to confuse what is described with the means of description.
— Wayfarer
I misunderstood what you meant by “are the mathematical laws themselves physical.” Now that you’ve explained, I agree with you. — T Clark
The problem with those presuppositions is that denying them, and asserting the opposites doesn't necessarily result in contradiction. — Corvus

That's too strong, I think. What we can know about natural laws are through certain mathematical equations, this only means that we understand the mathematical aspects of nature, not other aspects. It's not at all implausible to think there is more to nature than what our equations tell us. — Manuel
[10] Something can not be created from nothing.
— T Clark
It would make no sense. Would it be impossible? I don't know. Perhaps we have a misleading picture of nothing. — Manuel
Great thread by the way. — Manuel
Not to pull this back to reference magnetism, — J
the two approaches could be contrasted and understood without necessarily needing to employ the term "real" or "reality." "What does the the word 'reality' refer to?" is non-substantive. "Can we know anything apart from our own interpreted experiences?" is substantive. Or at least as substantive as such a highly abstract inquiry can be. — J
But it makes a point about an inherent contradiction in physicalism. — Wayfarer
It is, as you say, one of the main reasons to reject physicalism, at least as it's usually understood. — J
The question that jumps out at me is: are the mathematical laws themselves physical, and, if so, how? — Wayfarer
Another question is about your understanding of ‘formal and final causation’. — Wayfarer
Did they really think there was nothing that couldn't eventually be understood? Or does it only mean 'partially understood' or 'sufficiently understood'? — noAxioms
Pre-20th century, sure, but also post renaissance. — noAxioms
Norton's dome — noAxioms
Was this never challenged? It being false is a nice retort to say Zeno's attempts to drive a continuous universe to absurdity. — noAxioms
Your 11-14 seem to require discarding some of the previous presumptions. Less so with 15-19, but still not compatible with 1-10. — noAxioms
The amount of energy is frame dependent. Matter wasn't back then. Nobody suggested that the two were interchangeable. — noAxioms
Dark matter cannot be seen or measured, but it affects stuff that can be measured. — noAxioms
But it's not objective. It's subjective — noAxioms
I don’t know about the others, but this one has often interested me. This statement seems to capture what I see as the foundational metaphysical assumption of science: that there is an objective reality which humans can understand. — Tom Storm
do these patterns tell us about reality itself, or only about the ways humans organize and interpret our experiences? — Tom Storm
That doesn't make it a presupposition though. That just makes it a practical reality. It's a practical reality that we have access to physical objects, can smash them into each other, and so it's a practical reality that if we want to predict the future of the world we live in, we can only do so using the stuff we have access to. — flannel jesus
To say physics presupposes all their is is matter, is like saying botany presupposes that all there are are plants. I mean ffs Newton himself wasn't a materialist. — flannel jesus
That's not a support of the presupposition claim you made, — flannel jesus
whatever "law" may ontological mean, but you need not pressuppose EVERYTHING is lawful. — flannel jesus
You'd have to define "law" first. — flannel jesus
All a principle or law is is a generalization of a regularity in the results of observations and measurements. In order for science to be useful, you have to be able to abstract a general feature of behavior. Otherwise, all you can do is talk about specific instances of phenomena. Again--It's something you can't do physics without. — T Clark
Okay, well this one's too weak to even argue about then. Not a presupposition of science, apparently merely a common belief of scientists. — flannel jesus
I actually think that's the most important thing here - for you to define exactly what you mean when you call this things presuppositions of science, or physics, or newtonian physics or whatever the boundaries of this conversation are. To me, it means "someone cannot participate in the social endeavour we call Physics without assuming these things to be literally true". — flannel jesus
Do you have to assume all that crap is literally true to notice and try to figure out these patterns? — flannel jesus
I just thought maybe you'd want to get a correct understanding of the scientific views you're discussing. — frank
I think if you look into it further, you'll discover that I'm right. Energy is a scalar number that measures the capacity of a system to do work. There's an awesome Spacetime video in which Dr O'Dowd explains it really well. I've posted that video three times so far on this forum. But you can also discover the information elsewhere. :grin: — frank
Energy is a number, not a substance. — frank
I don't think most of these are presuppositions of science. — flannel jesus
1. I mean, science is an attempt to understand the universe by humans, so... yeah this one's a presupposition, but a rather agreeable, obvious one. The alternative to trying to understand the universe is not trying, and not trying doesn't seem to have many returns on (non)investment, so we might as well try. — flannel jesus
2. Nope, not a presupposition of science in the slightest. Science has access to matter, and thus that naturally makes it easier to find out things about matter than ... things we don't have access to. It's not a presupposition of science, our focus on the physical is just an inevitable consequence of what it means to do science. — flannel jesus
3...just because science tries to find principles and laws to describe behavior doesn't necessarily mean that in order to do science, one must presuppose substances all behave consistently in according with those principles and laws. — flannel jesus
4...It happens to be the case that a lot of what we know about matter is describable mathematically - the fact that that's the case doesn't require a presupposition that it's a universal truth. I don't think this one counts. — flannel jesus
5...Most scientists presuppose this, I think, but I again don't think it's a necessary presupposition. Someone could easily conduct science without that presupposition, right? Like one can imagine certain things we call laws fluctuating over time. — flannel jesus
6...many scientists I'm sure are very questioning of the very concept of causality itself. — flannel jesus
7...Not a presupposition. This is a belief that's a consequence of experience and observation. If human scientists lived in a different universe where we experienced and observed very different things, we could easily have a science that has substances which are destructable. Come to think of it... don't matter and antimatter destroy each other? I give this one a 0/10, big fat NO on that being a presupposition. — flannel jesus
8...Not a presupposition. Not even a universal belief among scientists. — flannel jesus
9...Definitely a big fat no on this one. Separate? Have you literally never heard of spacetime? — flannel jesus
10...Not a presupposition. At best, it's a similar situation to 7 - a belief that arose from experience and observation. Different observations could have yielded a different scientific belief. — flannel jesus
this about presuppositions of science, or of scientists? I'm not sure the former makes any sense. The latter is an empirical question only answerable by a survey, no? — bert1
Energy isn't a substance. It's a physical construct, which means it comes from the analysis of an event. — frank
This is really interesting, I've been contemplating about how consciousness relates to existence and its seeming duality. I'm planning a post about such a thing right now, maybe the Tao Te Ching would have more to say about it. — QuixoticAgnostic
Here's a new paradigm I recently read about: On biological and artificial consciousness: A case for biological computationalism. This one isn't phenomenologically informed, per se, other than the fact that it reflects openness to a somewhat fresh start. — Relativist
My main point was that there is no incoherence or inconsistency in thinking that the physical world existed prior to the advent of consciousness. Science informs us that it did. The fact that such judgement is only possible where there is consciousness (and language for that matter) I see as a mere truism. — Janus
Maybe I'll start a thread with lists of statements I consider metaphysical by my standard and ask people to describe how they fit into their own understanding of the term. — T Clark
There have been quite a few threads about metaphysics recently and everyone is tired of them… Oh… wait a second… I’m not. I have a specific focused topic in mind that might allow us to avoid the usual confusion.
First focus - the discussion will take place from a materialist/physicalist/realist point of view. These from Wikipedia:
Philosophical Realism - Realism about a certain kind of thing (like numbers or morality) is the thesis that this kind of thing has mind-independent existence, i.e. that it is not just a mere appearance in the eye of the beholder.
Physicalism - In philosophy, physicalism is the metaphysical thesis that "everything is physical", that there is "nothing over and above" the physical, or that everything supervenes on the physical.
Materialism - Materialism is a form of philosophical monism which holds matter to be the fundamental substance in nature, and all things, including mental states and consciousness, are results of material interactions.
Second focus - For the purposes of this discussion, we live before 1905, when the universe was still classical and quantum mechanics was unthinkable. I see the ideas we come up with in this discussion as a baseline we can use in a later discussion to figure out how things change when we consider quantum mechanics.
Third focus - We’ll stick as much as possible with issues related to a scientific understanding of reality. Physics in particular.
R.G. Collingwood wrote that metaphysics is the study of absolute presuppositions. Absolute presuppositions are the unspoken, perhaps unconscious, assumptions that underpin how we understand reality. Collingwood wrote that absolute presuppositions are neither true nor false, but we won’t get into that argument here.I would like to enumerate and discussthe absolute presuppositions,the underlying assumptions, of classical physics. I’ll start off.
[1] We live in an ordered universe that can be understood by humans.
[2] The universe consists entirely of physical substances - matter and energy.
[3] These substances behave in accordance with scientific principles, laws.
[4] Scientific laws are mathematical in nature.
[5] The same scientific laws apply throughout the universe and at all times.
[6] The behaviors of substances are caused.
[7] Substances are indestructible, although they can change to something else.
[8] The universe is continuous. Between any two points there is at least one other point.
I think some of these overlap. I’ve also put in at least one because I think it's pretty common, even though I think it might not belong. I would like to do two things in this discussion 1) Add to this list if it makes sense and 2) Discuss the various proposed assumptions and decide if they belong on the list. — T Clark
I don’t see that passage as advancing a metaphysical position. It doesn’t make claims about what exists in itself, but about what scientific objectification leaves out by design. That’s a methodological and epistemological point about the conditions under which scientific knowledge is produced, not a thesis about the ultimate nature of reality. — Wayfarer
subjectivity is not a possible object of perception, as it is that to which or whom experience occurs. — Wayfarer
Interestingly then, based on that thread, it seems that the question and the three answers I give in the OP is almost a moot point; any of the answers might be correct according to some way of thinking about the question, and trying to claim any one of them most accurately answers the question along its terms is just trying to claim language rather than discuss the concepts.
That said, part of me posting this in the first place was an excuse to propose a way of viewing existence such that the third answer is valid, although I don't know if I succeeded there. — QuixoticAgnostic
One might say, existence and non-existence are two sides of the same coin, so where we say a thing exists, we also introduce the possibility of that thing failing to exist. — QuixoticAgnostic
When people see some things as beautiful,
other things become ugly.
When people see some things as good,
other things become bad.
Being and non-being create each other.
Difficult and easy support each other.
Long and short define each other.
High and low depend on each other.
Before and after follow each other. — Tao Te Ching - Stephen Mitchell's translation
The tao that can be told
is not the eternal Tao
The name that can be named
is not the eternal Name.
The unnamable is the eternally real.
Naming is the origin
of all particular things. — Tao Te Ching - Stephen Mitchell's translation
What 'metaphysical claim' do you think is being made? — Wayfarer
For Bitbol, phenomenology is the real starting point in the quest to understand consciousness, because it reveals something that scientific objectification systematically brackets out or ignores — namely the observer, the scientist, the one who makes observations, draws conclusions, and decides on the questions to be asked. Yet the point runs deeper than methodological oversight. Scientific objectivity does not merely forget the observer; it presupposes the observer as the one for whom objects appear, measurements make sense, and evidence is meaningful in the first place. Before there can be data, models, or theories, there must be a lived field of experience in which anything like a “fact” can show up at all. Phenomenology begins from this pre-objective dimension, revealing the conditions that make scientific inquiry possible but that science itself cannot capture because they are already assumed in every act of objectification. — Wayfarer
There's a categorical distinction you seem to be missing. Where in the world of apples and pogo sticks is your experience? — Wayfarer
Bitbol’s alternative is not a metaphysical theory — Wayfarer
Phenomenology begins from a simple but far-reaching insight: the reality of first-person consciousness is ineliminable, and any account of the world must ultimately be grounded in the structures of experience as they appear to the subject. — Wayfarer
At its core, phenomenology is the disciplined study of conscious experience from the first-person perspective...consciousness is not an object among objects, nor a property waiting to be discovered by neuroscience. It is not among the phenomena given to examination by sense–data or empirical observation. ... — Wayfarer
If we know what consciousness is, it is because we ourselves are conscious beings, not because it is something we encounter in the natural world. (We may infer that other sentient beings are conscious, but only our own consciousness is immediately given to us.) — Wayfarer
Bitbol considers consciousness to be “self-evidentially absolute” — Wayfarer
From this perspective, the materialist project of locating consciousness in the brain or in neural processes is not just incomplete; it is conceptually incoherent. Like any empirical analysis, it rests on the presumption that what is real is what can be objectively measured and assessed. (Here I am referring specifically to the empirical sciences — physics, neuroscience, and biology — which construct their claims through measurement and intersubjective verification.)
However, the very notion of the objective world described by the empirical sciences is itself a product of selective abstraction — what Bitbol calls the end-product of the procedure of objectification. Why? Because science methodically brackets out the subjective pole of observation so as to arrive at an intersubjective consensus about the observer-independent attributes of the object. But when this methodology is applied to the question of the nature of consciousness, it turns around and tries to explain conscious experience in terms of that consensus. — Wayfarer
The result is not only circular but, he says, will always culminate in the notorious “hard problem”: consciousness treated as if it were something that emerges from structural relations in objectively–existing matter, when in reality it is the precondition for identifying those relations in the first place. — Wayfarer
This is paricularly true of culturally influenced feelings and behaviors, like love and hate. Of course it is possible (even probable) that a trait or behavior that has become common has conferred advantages, but assuming it must have done so is an error — Ecurb
