Logic & RealityIn the previous post, I attempted to lay out some of Peirce's argument that the meaning of any concept, by necessity, is tied to the the sensible effects that one might expect ... and I tried to make it clear that 'sensible', here, means something like "sens-ABLE." If we are talking about two different concepts, the thing that differentiates these concepts is that they will lead to different sensible effects. The example I was blathering about previously is Peirce's own--namely, transubstantiation. For Peirce, two conceptions that don't yield different sensible (and we might, for our purposes, occasionally say 'practical') effects
ARE NOT DIFFERENT CONCEPTIONS.
I tell this to my students, and they glumly record it (sometimes eagerly, but this is almost ALWAYS a sign that they are hoping to be "conceived" of as so interested and busy that I should not ask them, say, a direct question) and then raise their lumpen faces conveying two things: Firstly, that they are far, FAR too cool to care what some dead guy said; secondly, they mutely convey some form of the opinion "So what, dude?" Perhaps transubstantiation is a bad example. Those who have an opinion probably don't realize that their opinion is something like
metaphysical, and those who don't see the issue as worthwhile--perhaps for pragmatic reasons themselves?--have a hard time seeing the implication of this stance. So, in order to round off my little Peirce-a-thon, let's look at the end of the essay
How To Make Our Ideas Clear. So what?
Here's what.
(Dude.)
Recall the "maxim of logic" that Peirce calls "the method of pragmatism" interchangeably with "the method of science":
"
It appears, then, that the rule for attaining the third grade of clearness of apprehension is as follows: Consider what effects, that might conceivably have practical bearings, we conceive the object of our conception to have. Then, our conception of these effects is the whole of our conception of the object."
N.b. what this rule purports to be. We might wish it to be clearer, but Peirce--intent on helping us out--turns to examples. What do we *mean* when we say that something is "hard"? In the end, argues Peirce, we mean that that thing can scratch other things. To wit, quoting his mighty Peirce-ness ... -icity. Like-ness. Anyways:
"
Let us illustrate this rule by some examples; and, to begin with the simplest one possible, let us ask what we mean by calling a thing hard. Evidently that it will not be scratched by many other substances. The whole conception of this quality, as of every other, lies in its conceived effects. There is absolutely no difference between a hard thing and a soft thing so long as they are not brought to the test. Suppose, then, that a diamond could be crystallized in the midst of a cushion of soft cotton, and should remain there until it was finally burned up. Would it be false to say that that diamond was soft? This seems a foolish question, and would be so, in fact, except in the realm of logic."
We know that Peirce has a hard- ... um, a great love ... er, sort of a mental chub- ...
a great deal of respect for logic. Dilettantes like myself might be reminded of the question, so often brought up by undergraduates trying to participate (and who have not read that day's assignment): "If a tree falls in the forest ... does it make a sound?" A question that, in it's original context, was putatively designed to investigate the question of the extent to which human beings contribute, in some way, to the information that we
receive. The idea that humans are active participants in the accumulation of their own wealth of knowledge is sometimes called
humanism. This can mean a whole bunch of things, depending upon who's talkin'. Let me say, right now, two things: 1. Peirce was religious, in a very strange kind of way, and 2. was on occasion of the opinion, trumpeted among the
deists of the Seventeenth and Eighteenth centuries, that god wants us to figure things out with reason. Bringing me back, however the producers of Viagra might like a different definition of 'hardness', to Peirce's conviction that the Pragmatism he is espousing is a Logical Maxim.
Do you find Peirce "logical?" Perhaps you do not; but I am willing to hold my disbelief in abeyance while Peirce attempts to convince me. We know that diamonds are hard because ... well ... the diamonds in our experience are hard. They scratch glass, many metals (if not adamantium, so Wolverine is safe, I guess) and people silly enough to test expensive drills on themselves. There are a number of things conflated by our
everyday understanding of the questions that Peirce is asking. Consider just one: how do we
know that that thing in the cotton is a diamond? How would we find out? When cops on television want to test a diamond for being a diamond, they scratch something. But until they do ... the
fact that diamonds are hard is based on our experience with diamonds. I'll take that further and say what we know about diamonds is based on the sensible effects we receive from diamonds. To make a long boring story short, we would only know that that diamond in the cotton is a diamond if we tested it, but before we do ... can we be sure it's a diamond? Therefore, logically ...
Okay, okay, enough of that. It's a harder question to answer than you might think. I push it in particular ways because I see Pragmatism in different ways than Peirce, and in fact as a (logical?) outgrowth of
Empiricism. I only mention these concerns because epistemological concerns indicate one of the many ways in which these questions quickly become difficult. There are many others.
In fact, if you want a clearer exposition of the ways in which sensible effects convey meaning, dig into the link to the article, and check out what Peirce has to say about force, using vectors. If you are clear on how vectors can be added together (say; on a boat, against the current, with a sideways tailwind), it should be clear that a nearly infinite combination of vectors can yield a particular solution. But the way in which we compare these manifolds is tied to sens-ABLE effects. Capisce? Let's get jiggy with the main point of "How to Make Our Ideas Clear." And I'm going to go ahead and stump for the application of the third grade of clearness of apprehension to the concept of "Reality," as the main point of this article.
"
Let us now approach the subject of logic, and consider a conception which particularly concerns it, that of reality. Taking clearness in the sense of familiarity, no idea could be clearer than this. Every child uses it with perfect confidence, never dreaming that he does not understand it. As for clearness in its second grade, however, it would probably puzzle most men, even among those of a reflective turn of mind, to give an abstract definition of the real. Yet such a definition may perhaps be reached by considering the points of difference between reality and its opposite, fiction. A figment is a product of somebody's imagination; it has such characters as his thought impresses upon it. That those characters are independent of how you or I think is an external reality."
Remember 'clear' & 'distinct?' Well here they are. Anyone who reacts to reality is "clear" about reality. Anyone who can define reality as that which is independant of what anyone thinks about it, is ... uh ... "distinct" about reality. But Peirce claims that
logically, we have a "right" to a "third grade of apprehension of clearness," which he takes his logical maxim of pragmatism to provide. The question therefore remains, what might the method of pragmatism applied to the question of the meaning of 'reality' tell us?
Here, then, let us apply our rules. According to them, reality, like every other quality, consists in the peculiar sensible effects which things partaking of it produce. The only effect which real things have is to cause belief, for all the sensations which they excite emerge into consciousness in the form of beliefs. The question therefore is, how is true belief (or belief in the real) distinguished from false belief (or belief in fiction).Because "reality" has only one effect, it has only one function. Peirce say that this function is to cause belief. Some are good, and some are bad ... how can we tell which are which? In their full development, according to Peirce, the terms 'truth' and 'falsehood' "appertain exclusively to the experiential method of settling opinion." If you remember the very first method of fixing belief, or that of tenacity, you'll remember that it involves clinging tenaciously to your beliefs. For someone of this temper, 'truth' ends up meaning "those things I believe." Remember my friend who wouldn't read Darwin? She didn't have to ... she knew the "truth."
Peirce calls "shenanigans!" on this conception ... or at least claims that it cannot constitute a "fully developed" model of truth and falsehood. A reflective thinker (Peirce!), a thinker who understood the limitations of the methods of tenacity, authority, and the
a priori method; a thinker who has given some consideration to the question of how the humans species' state of the art assessments of reality change over time realizes that continued investigation gets us further toward *THE* answer. Peirce seems to have what some would call a "limit" theory of truth. We (at least, those who investigate) are led towards the truth. As Marty McFly might have it, the truth--which describes the real--is our 'density.' To wit:
This activity of thought by which we are carried, not where we wish, but to a fore-ordained goal, is like the operation of destiny. No modification of the point of view taken, no selection of other facts for study, no natural bent of mind even, can enable a man to escape the predestinate opinion. This great hope is embodied in the conception of truth and reality. The opinion which is fated to be ultimately agreed to by all who investigate, is what we mean by the truth, and the object represented in this opinion is the real. That is the way I would explain reality.So ... how do we know if the answer we have right now is "true," and therefore describes the real?
We don't. But if we are applying the pragmatic method, the logical maxim which ties the meaning of concepts and theories to sense-ABLE effects, we will take new evidence into account. And it is this
method that Peirce is pushing. His friend James enjoyed saying that Pragmatism is a method and an orientation towards truth, but stands for no particular results.
How do we guard against sitting down contented with the wrong answer? By employing the pragmatic method, or the method of science. Peirce wants to define reality as that "opinion which is fated to be ultimately agreed to by all who investigate." Peirce means by 'investigation' the pragmatic, or scientific, method. Reality is what scientists will eventually agree on. Huzzah!
At first glance, it looks as if Peirce has given us a definition of reality that is opposed to our conception of 'reality' in the "second grade of apprehension of clearness:" that which is independent of what is thought about it. Doesn't Peirce's approach make reality dependent upon our thoughts? Peirce says not so, or more accurately, reality depends upon thought in general:
But the answer to this is that, on the one hand, reality is independent, not necessarily of thought in general, but only of what you or I or any finite number of men may think about it; and that, on the other hand, though the object of the final opinion depends on what that opinion is, yet what that opinion is does not depend on what you or I or any man thinks.So. There you go. Peircean pragmatism bypasses static and categorical uses of 'truth' and 'reality' by taking account of 1) How we actually do fix beliefs, and 2) What we mean when we say that something is "real." Let me raise one more topic, in the hope that any clearness I have "crushed to earth" earth here might rise ...
The meaning of terms, like the meaning of concepts, depend upon how they are used (to be more specific, they depend upon sense-ABLE effects that we expect). We tend to use 'truth' and 'reality' in at least two ways. When teaching I differentiate between T1 and t2. Truth1 is our intuition that there is an absolute objective truth "out there" that we describe when we are telling THE truth. But we all know that there are things that are "true2 to ME" which are not true to others.
E.g., I believe that "The Boy Bands of the 90's were absolute trash, and everyone who listened to them suffered irreparable aesthetic harm." But they sold millions of albums. Am I right? We all know that aesthetic opinions are not True1, or objectively true in the first sense. [I yet believe history will vindicate me, n.b.] Nothing makes my conclusion better than my friend Dan Suh's conclusion that "The Backstreet Boys kick ass!" I believe my conclusion, not Dan's, but I'm describing the world as I understand it. Dan is describing the world as he understands it.
What about our ideas about, say, the atomic weight of lead? Can I be wrong in that? Certainly. In fact, I haven't a clue what it is. But I know there is an answer, that has been arrived at through experimentation (read investigation of sense-ABLE effects). Within the confines of our understanding of atomic weights, an answer has been reached. We think of that answer as "objectively" true; unlike my hatred of 'N Sync. But both kinds of conclusion are the same, because of the ways in which we fix beliefs.
A "good" or "true" belief, even if it is a belief about objective reality, takes the sense-ABLE evidence into acount. This doesn't mean it can't change--look at the history of science!--but it gains its status from the method applied, not the conclusion itself. Capisce?
Peirce is a scientist. He believes that science approaches the truth, defined as a description of the real, and known only by its adherence to method. Chew on that, and I'll have another run at this topic through the philosophy of James in a later post.
Happy Holidays!
