>Option 0: Paranormal phenomena are not part of the world of physical phenomena at all; they do exist, but they come from a "spiritual world".

>- This is an option I added in response to some reactions I received on the previous version of this little essay. There still exist people who think that parts of our world simply disconnect from everything that we have been able to sort out and investigate systematically, and which we discovered to obey physical laws with staggering precision. My friendly advice to such people is to immediately throw away their mobile phones, television sets, automobiles and medicines since these were built on the assumption that laws of nature never fail. Please go back to the Stone Age, where you belong.

>Option 1: There is a physical effect not yet recognized by physicists, allowing information to be transmitted in novel ways.

>- What kind of effect could this possibly be? It has to be so weak that it went unnoticed in all physics experiments. These experiments are tremendously more sensitive than brain tissue and the like. Deviations from the Standard Model can only be expected in extremely high-energy particles or extremely weak interaction phenomena. The first cannot be emitted by brain tissue, the latter cannot be detected by brain cells. But there are many other reasons why this option can never work. The purported signal(s) should not only be able to move backward in time, over unlimited distances, from dead bodies, etc., but also carry information in a form that brains can encode and decode without any practice (unlike the ordinary senses). All these features are completely uncharacteristic for all physical phenomena, so it will be extremely difficult to keep this option up.

>Option 2: All reported events are due to chance coincidences.
>- One gets the impression that this is too improbable to be true. It is not as improbable as the first option though.

>Option 3: People who make claims for the paranormal are liars and charlatans.
>- This option is often adhered to by the extreme skeptics. No doubt, there will be liars and charlatans among the reporters, but this does not explain why the claims are so frequent, and one has the impression that the claims are generally made by honest people. Although this option is more difficult to exclude than the previous ones, it is still not quite satisfactory.

>Option 4: We are dealing with a delicate psychological phenomenon; people "want to" believe these things so badly that these are mistaken for the truth.
>- According to this option, we are dealing here with a purely psychological effect. The purported observations of paranormal signals were imagined but not real. Signals received from loved ones who have mysteriously disappeared, are wanted so badly that people really believe they received them. Even though this may sound like an improbable explanation to you, it is definitely more probable than the preceeding options given. But it brings me to a related option:

>Option 5: People can be tricked by their own brain.
>- Imagine a computer memory. It should be easy for any programmer to falsify the date of a file in it, and date it backwards in time. From then on, the computer will treat the file as if it was put there at this earlier date. If compared with later events, the file could appear to be a `paranormal signal'. Our brain could make the same mistake. If somebody tells you: "today something happened that I dreamt about in all detail last week", then how do you really know that the dream took place last week? Your memory has a `date label' attached to each memorised event. It is well-known that these date labels can be inaccurate. It is not against any law of physics to suspect that heavy emotional disturbances can cause our brain to antedate its memories.

Strawman
Prove empiricism using only empiricism.
I'll just answer for you, since you refuse: you cant.
Hence, empiricism is not the only valid means of acquiring knowledge. In fact, the main principles of science, the verification and negation principles, cant even be affirmed by their own standards and must resorting to some kind of rationalism

>It's not irrelevant. It's the subject of the conversation

Wrong. You said “valid”, not “true”.

>You're saying something is true only if it is practically applicable.

Wrong. I’m saying empirical data is practically applicable so it is valid. It provides consistent, useful results that can be used to model reality and predict the behavior of the things within it.

>> No.10960268

>>10960253
nice strawman. that's not what he's saying. something is true only if it is empirically verified. something is incontrovertibly true if it goes beyond the context in which it was proposed to predict new things like new applications.

the sky is blue has to do with rayleigh scattering. rayleigh scattering comes from classical E+M. classical E+M leads to lots of great things that it wasn't originally intended for, like electric generators and EMP weapons and special relativity.

anyhow, i am sure you will apply your community college degree in philosophy to keep arguing semantics. but please admit that your computer and monitor are thanks to physics. ok?

None of that demonstrates how the sky being blue is applicable. You've only applied Rayleigh scattering.

it is, if you ignore the fact that things that work actually work, you know like your gas pedal makes the car move forward, or you clicking internet explorer actually opens an internet explorer window.

if you divorce yourself from facts like those, then sure, it seems like a logical trick, but with science, you should realize that the things you interact with in life, like cars, computers, food, TVs, faucets, lights, HVAC systems, etc. etc. all are empirical/scientific things. and if you think that is just "tautology" then you need a reality check.

i am not trying to refute rationalism. i'm just trying to get you to realize that from a practical standpoint, the empirical mindset is massively successful and has provided you with all the stuff you rely on in your life. it works. OTOH rationalism a la Descartes has led to nothing but philosopher circle-jerking, so i tend to treat it on a similar status as alchemy, flogiston, or "gender studies"

metaphysics is a philosophical exercise one can indulge in to clarify one’s scientific (empirical) beliefs. it has equal probability to the scientist to lead them to good ideas as leading them to bad ideas. for einstein, it basically neutered him scientifically after 1925. so my feelings are that one should not be lured into philosophy

sure. what is "good" and what is "right" are not scientific. that's basically a value judgement that can't be answered scientifically.

i don't think these questions are meaningless though. it's just that i definitely remove my "scientist" hat before trying to speak about them, since a good scientist should have nothing to say about them

I was reading something today about the difference in ontology and epistemology. Ontology being the study of what is there, what exists, while epistemology is only observing what it is like. The criticism of empiricism is that it takes the epistemology without the ontology. Would you accept the criticism that empiricism is only good for describing what existence is like rather than what existence actually is?
