I
really wish that students of hard science would
have to take some rudimentary classes in
Logic &
Philosophy. As it is, most have no respect for these longstanding and very deep sciences. Thus, they assume that these fields are easy, and engage in them without any thought for proper terminology or the history of knowledge and thought in them. There are some
very bright folks who dedicated their lives to thinking through these things.
Just as it is with Chemistry or Physics, the opinions of people who haven't studied at least to a certain point are regarded by those who
have studied the subject with a vaguely tolerant condescension. If someone came to you arguing about a complex chemical reaction or an engineering problem, but had not even studied the periodic table, or was ignorant of the basic laws of physics... you know how you would react.
Yet, it is very common for such hard scientists to wax philosophic in fairly amateurish terms, or speak on matters of logic as if they were authorities. Sadly, most of them know almost nothing about either subject.
I think most scientific materialists
assume that their beliefs are logical. Many go even further, and guess that due to their heavy involvement in one branch of science, that they are qualified to speak about logic, knowledge, reality and the like without having even cracked a single book. The idea is that science is founded in logic and reason, and the scientific method is the height of logical, rational inquiry.
Unfortunately, this is simply not true.
According to Logic & basic Philosophy, SCIENCE is
irrational and most of its conclusions
illogical.
This is primarily due to the use of
inductive reasoning in science. Logic has this well argued idea that induction is not reliable as a proof in an argument because it is the basis of a good many of the known logical fallacies. It is called
The Problem Of Induction and in Epistemology (the study of what is knowable), the best such reasoning can achieve is some kind of probability conception based on the past.
And, as we all know... just because you see a woman walk her dog at 8am every Monday for 3 years, this is not any kind of proof that she will walk her dog NEXT Monday. (Dog could have died, she could have moved, could be ill... on vacation.) In actuality, the longer the streak goes where she
does walk her dog on Monday, at some point, the likelihood actually becomes GREATER with every instance that she will not be seen to walk her dog on the next Monday. [
analogy shamelessly borrowed from Wikipedia]
As much as we would like to believe differently, most of science is actually on ground
nearly this shaky... logically speaking.
In fact, this
solipsism that you all seem to despise so much is actually much more solid a belief system than anything scientific materialism has to offer. It can not be disproven. Scientific theories (even quite useful working ones) get disproven all the time. Ptolemy, Copernicus, Newton, Einstein... all of them have had things they stated as fact turn out to be false.
Also, there is no reason a solipsist can not be as moral or ethical as a materialist. I would even venture to say that most of the so-called evil acts of the world have been perpetrated by materialists. I can't even think of any sociopaths who were truly solipsists. Scientific Materialism does not lead to philanthropy more often than it does to misanthropy IME.
There is a type of solipsism that is agnostic rather than metaphysical. This Epistemological Solipsism is actually a very logical stance to take. It states simply that one can not say for
sure anything is real other than that one seems to be experiencing something, and in fact... the existence of anything other than oneself is impossible to prove. As is the idea that you are not dreaming.
Materialists just shrug this off, and brusquely skip past it.
But in the study of Philosophy, Materialism is not the only game in town... nor is it even the most widely accepted philosophic stance. Idealism and Rationalism (yes,
rationalism is a philosophy that is opposed to materialism) have plenty of adherents because they stand on more logical footing. As do a half dozen other reasonable conceptions of existence and knowledge.
Anyway, I am not trying to burst any bubbles here. It just seems that the Nexus should be a place where the level of debate is higher than most. People here at least aspire to maintain a high level. Hard scientists tend to appropriate terms that have historically agreed upon definitions and reams of books written about them, and use them in ways that don't coincide with the accepted definitions. Since people on this thread are discussing some of the central issues of Epistemology (Descartes called it First Philosophy), it seems that we should at least recognize the Philosophy 101 stuff that goes with it.
Personally, I am extremely pragmatic. Whatever works best is the method of choice, AFAIC.
Reality is mostly a moot point. Believing in
any reality too strongly is likely to lead you astray. But this is true for Quantum Mechanics as much as it is for Hyperspace being real. Maybe even moreso. Nobody ever built billion dollar machines that could annihilate a city the size of Geneva just to prove the existence of machine elves.
