actually no, and i don't understand where you're even coming from. if you're saying "knowing floating is about buoyancy and displacement is based on some sort of physics which i magically claim to be purely rationalistic" then i would point out that quantum mechanics is notoriously incapable of predicting crystal structures formed by solids, and you could _never_ _ever_ derive from first principles that ice is less dense than water.

the reason we know ice is less dense than water is based on observation. for sure.

>i can tell you for a fact that if i put an ice cube into a glass of water, it's gonna float, not sink to the bottom.
On earth, in space however the water will surround the ice. "Floating" is ultimately no longer an empirical fact so "ice floating in water" makes absolutely no sense.
Also you're talking about two different qualities of the same thing; water. You have presented absolutely no empirical facts because what you are talking about is completely qualitative.

False observations happen all the time, you hallucinate and see mirages every day, and thus reveal nothing.
Obviously empirical results hold weight and can be reproduced and should be considered. But they are not as powerful as rationalist logic and deductive reasoning, and they still are founded upon an apriori acceptance of rationalism and logic.

>Logid is independent of human beings or the mind
Logic, like mathematics, is completely a fabrication of the human mindscape. Logic and reason are inextricable from the human brain and are subject to every computational failure and bias that the human brain can muster. Even cultural biases, like proportional or logarithmic thinking can impact one's ability to reason effectively.
>the world isn't deterministic
Prove it. A machine can be built to flip a coin and, under the same conditions, always receive the same result.

This is false. A human making a mistake in logic, does not mean logic is tied to human beings. Much like humans making a mistake ina measurement, does not mean the thing being measured act in the false way.
Logic is external to humans, like physics is external to humans. However, physics is built up from logic, logic is not built up from physics. It is more fundamental than physics.
>Prove it. A machine can be built to flip a coin and, under the same conditions, always receive the same result.
This has been proven for a hundred years now, by physicists in fact. Determinism hasn't been a valid epistemology for a century.

That explains why you are so ignorant of reality.

At this point the pair of you are arguing about something completely tangential to the OP, so I will drag you back. Image how backward we would still be if we hadn't realized that empiricism and experimentation matter? Imagine the state of our existence. What does it even mean for "epistemology to be superior"? Nonsense.

How does uncertainty disprove determinism? The rules of quantum mechanics are entirely deterministic.

>> No.10096063

>>10096058
maybe they are, but the results of empirical measurements are subject to uncertainty. meaning that if you believe there is a deterministic description of the universe, then the results of measurements are only related to one particular branch of that description

>> No.10096070

>>10096063
So we have it that QM and all other known physical theories are deterministic. Obviously our universe isn't "made" of physical laws, merely described by them [to an unreasonable degree of accuracy]. But all measurements have inherent uncertainty. Can you show this implies a non-deterministic universe?

>> No.10096074

>>10096070
there is no deterministic method that describes which branches the measurements we do will correspond to. there is a probability distribution which describes how measurements will turn out, and that's the ultimate prediction we can make. the science says that measurements are probabilistic in this universe, so therefore even if you believe in some "universal wavefunction" that evolves deterministically, that still says nothing about how your measurements go to one particular outcome or the other -- it's random. which is incompatible with deterministic.
