|Why is it that you physicists always
require so much expensive equipment?
Now the department of Mathematics
requires nothing but money for paper,
pencils, and waste paper baskets and the
Department of Philosophy is better still.
It doesn't even ask for waste paper baskets

Invention or Discovery?
|Did the fathers (and mothers) of
quantum theory, (statistical) thermodynamics, theory of relativity and so on
invent the basic laws of those science
fields or did they find them? This is a
meta science question; a question not
of science but about science. An answer thus must come from
philosophy, not from science.
Philosophy can't tell, however. This might appear surprising but ask yourself: when was the last time that philosophy actually could tell something by making an unambiguous statement about some basic truth?
|Actually, it's pretty much only philosophers that can't tell. Everybody else can. So, what exactly is the question?|
|Invention implies that the laws of nature as we know them are figments of human "thinking", whatever that implies, and given to changes as the way of thinking changes as time goes on. Non-humans like your cat, husband or goldfish, not to mention those slimy aliens out there, would have their own points of view about those laws, quite different from ours. There is no such thing as an absolute truth. Could that be the (absolute?) truth?|
|Aristotle's "laws of nature" were
quite different from what we have now (and completely wrong). The "phlogiston" of old, just as
the "ether" of not so old, gave way to thermodynamics and
electrodynamics as we know it now. It
follows that what we think or believe now
will be quite different from what we will think or believe in the future. All
of that is just made by humans and has no absolute significance whatsoever.
It also follows that other beings capable of "thinking" on some other planet or at some other time will invent something else for explaining nature that suits their particular needs. There is no such thing as absolute truth; at best we can come up with some crude approximations to something that is elusive, if existent at all, like you, for example.
|Finding implies that the basic laws of nature exist independent of humans or aliens out there, and that we can find some of the basic laws or perhaps, in due time, all of them if their is number is finite. Platon (and a throng of others) comes up in this context but I will not belabor that.|
|Absolute truth then exists in the form of
definite natural "laws". We can find them or at least parts of them.
When we describe these laws in the languages available to us (including the
language of mathematics) we are forced to use approximations because our tools
are not fully up to the task.
Look at your wife (or just somebody) and assume that her existence is a kind of absolute truth. Now describe her completely. You quite simply can't (the attempt probably would be dangerous, anyway). But does that imply that your wife does not exist exactly as she is? The "true name" concept comes in here as a mythical solution to the problem.
|So what shall it be? Are we going to abandon the concept of atoms one day and replace it with something else?|
|All scientists and most "normal" folks definitely say no! Somenot allscientific discoveries are absolute and will never change. Maybe the way we describe atoms will change but they are the same atoms.|
|Most professional philosophers tend to say yes! They would invoke a lot of big words like positivism, positive relativism, postmodernism, deconstructivism, and so on and simply deny that atoms have a reality on their own that is independent of what philosophers think. Everything is a human invention. Strange, though, that they never invented anything useful.|
|Well, those philosophers are wrong. It is as simple as that. They stick to the time-honored tradition that philosophers were nearly always wrong when they "think" about science. Aristotle, for example, was always wrong about scientific topics, even on subjects where he could have known better. That does not mean that he didn't do great things in other areas!|
|As an example, for
Aristotle steel was especially
pure iron: Wrought iron indeed
will melt and grow soft, and then solidify again. And this is the way in which
steel is made. For the dross sinks to the bottom and is removed
from below, and by repeated subjection to this treatment the metal is purified
and steel is produced"
Well. He is utterly wrong and will remain to be wrong till the end of days or hell freezes over, whatever comes first.
|What can you do with philosophers like this? Here is a thought:|
|Smelt them! I get somewhat ahead of myself here but smelting is the process where you turn not-so-useful ingredients into something desirable, like iron oxide into iron. How it is done can be seen in this painting from the middle of the 13th century that adores a ceiling of the St. Maria Lyskirchen in Cologne (Köln) Germany.|
|OK, you nit-pickers out there! Yes,
the picture actually shows the "burning" of the philosophers
after they had been converted to Christianity by St Catherine (the one with the
wheel). Considering that Christian philosophy is
even worse than the heathen
stuff of Aristotle and his ilk, the emperor (one Maxentius or Maximin) had no
more use for the guys and wanted them burned. This was traditionally done at
the stake but the artist of the picture above probably thought that this was
wasteful and that one could at least try to do better. His philosphers are
cleary fed to a smelter, a typical "Rennofen" of the time. Burning
something just produces CO2 and ashes, while smelting might turn
those guys into something useful like court jesters, maybe.
Well - it didn't work but there is no harm in trying.
