Originally (for the uninitiated) posted on the "What is matter in the quantum age" thread. Posted in this section but it could fit in on many different sections. My original question was, "How do we know the reality of anything without reference to the senses which are themselves workings of the mind, especially in light of quantum physics seemingly saying that subatomic particles seem to pass no test of existence themselves?" Anyone not previously involved in the discussion should perhaps look at the above thread.
This is the original post for this thread. I did take the time to go through all 136 postings to the thread
What is "matter" in the quantum age? It reminded me of a paper I wrote years ago in a course on the philosophy of science entitled "Is the Concept of Matter Obsolete?" My conclusion at that time was "Yes," based on many of the points made in that thread. What I noticed about the discussion in that thread was that much of it focused on so-called "physical reality," as if that was all there was to reality.
Now the first part of
housby's question is
How do we know the reality of anything? which I will rephrase slightly as
How do we know the reality of any thing? Therefore, to answer that question we must first understand what is meant by a "thing"? Our common conception of a "thing" is that of a so-called "physical object," such as a chair. But what is it about a chair that makes it a "thing"?
Ortega spent many years analyzing the concept of "thing." Of course it has a history going back to the Romans and the Greeks. The Latin word for "thing" is
res, from which the words "real" and "reality" is derived and for which the philosophy known as Realism was named. So that to a Roman the expression "real thing" would be redundant.
Now the Romans used the word
res as a translation of the Greek word
pragma (plural
pragmata), that the Greek philosophers used also to mean "thing." However, Ortega traced the original use of the word
pragma in Greece, before the philosophers adopted it, as having the meaning "concern" or, ironically, "matter," in the sense that we speak of what "matters" or is of "concern" to us as living human beings.
So what Ortega concludes is that what we should mean by "thing" is that which "matters" or "concerns" us in our lives. It is the "things" that are important in the lives of human beings that have been given names and isolated from the rest of the circumstances in which they occurred. Ortega would say that "things" exist to the extent that they "matter" or are of "concern' to a human being in her life.
It was the Greek philosophers, however, who raised the question about where those "things," and in particular physical things, came from, what was there "origin." The Greek word for "origin" was
physis, that originally meant "birth." Similarly, the Romans adopted the word
natura, which also originally meant "birth," as a translation of the Greek word
physis.
The pre-Socratics speculated that "things" had their "origin,"
physis, in water, air, fire, etc. However, what the later Greek philosophers did was to change the question of the "origin,"
physis, of "things" or what they came from, into a question of what things were "made of." And they speculated about "atoms," and "forms" and with Aristotle, "substance." [I won't get into Plato's "ideas," because that would take us too far astray.] It was assumed that what they were "made of" was "unchanging," and so the word
physis and later
natura came to have the meaning of unchanging "nature," as we often use the term today.
We now know that so-called "physical things" are not unchanging. And we think that, according to the Big Bang theory, there was even a time at the beginning of the present universe when there were no atoms, and even the so-called "elementary" particles were being "born."
Ortega was famous, at least for those who read him, for having said that "Mankind does not have a nature but rather . . . a history." It turns out that even Nature does not have a "nature" in the sense of being unchanging, but rather a history which includes a "birth," a "life," and a "death," as do we. It's time for the science of Natural History to regain it's stature.
I hope that this is useful in clarifying some of the confusion arising from the first question "What is the reality of any thing?" and leads us to a dicussion of the previous question "What is a 'thing'?" Then we can perhaps look at
housby's question with "new eyeglasses" to see if it still has any meaning.
Here's looking at you, kids! :flowers:
