Gary F., Gary R., Cathy Legg, John Kaag, Jerry, List,

Jerry says:  "My personal feeling about your exposition is that such a view of 
material and formal categories leads one into an extra-ordinarily deep 
philosophical morass from which you may never emerge."

At the Congress, several people expressed a worry about falling "down the 
rabbit hole" when studying Peirce.  The concern was that spending too much time 
on the difficult parts of the more challenging essays threatened to pose 
insurmountable problems in making sense of what Peirce is up to.  

Despite your warnings, I will have to trust my own judgment in determining when 
it makes sense for me to press on when it comes to the more challenging texts 
and arguments.  My conviction is that Peirce often is trying to teach us how to 
employ specific methods in doing philosophy, and that we'll struggle in our 
attempts to understand him so long as we lack the experience and skills he 
possessed.  I don’t know about you, but this puts me in a tough position, 
because I seem to lack much of his experience and skills.  While Peirce tried 
to put many things in the simplest possible terms, he often takes it for 
granted that the reader will "actively think" and draw on his sentences as "so 
many blazes to enable him to follow the track of the reader's thought."  (EP, 
301)

Reading Peirce presents a challenge.  As many scholars have pointed out, he was 
a remarkably talented logician, and he possessed an intimate familiarity with 
the mathematics of the 19th century and its larger history.  What is more, he 
was a practicing scientist who had a rich understanding of how to do and not 
merely read chemistry, astronomy, classificatory biology, and geodesy.  In 
addition to being a special scientist working in multiple fields, he had a 
synoptic sense of the history philosophy and the conceptual landscapes 
represented by different philosophical systems—along with a rich appreciation 
of the different worldviews that philosophers might try to explore.  Above all, 
he was a student of methodology, and his aim was to develop a systematic method 
for improving the methods of inquiry.

Turning from these remarks about the difficulties one faces in trying to 
understand Peirce's views--especially the more difficult arguments expressed in 
the more challenging texts--to the task of reconstructing some of Peirce's 
arguments in the text of "New Elements (Kaina Stoicheia)", let's take a look at 
the text itself.  There are three main sections.  The first contains 
biographical remarks about the textbook he wrote on the logic of 
mathematics--taking topology, projective geometry and metrical geometries as 
its subject matter.  The second contains a statement of the distinction between 
definitions, postulates, axioms, etc.  The third, which is the longest section, 
is divided into 4 sub-sections.  You quote from the fourth and longest of these 
subsections.

What is Peirce doing in the passage you've quoted?  It is possible that we are 
reading the text somewhat differently.  Let me provide a few of comments about 
what he is doing in the pages leading up to the passage you've quoted so that 
we might clarify some of the differences in our approaches.  I note that you've 
quoted the passage, but you've said precious little about what you think is 
going on here.  You refer to an earlier post by Clark, so perhaps I could turn 
to what he says at some later time in an attempt to understand your remarks.

So, in parts I and II, Peirce starts by referring to his own work on the logic 
of mathematics.  By the fourth part of section III, he has moved from a 
discussion of speculative grammar and critical logic to a series of examples 
drawn from the theoretical and the practical sciences.  You seem to be 
particularly interested in his remarks about the various specific uses of the 
concepts of cause and effect, including internal and external causes, along 
with material, formal, efficient and final causes.  He has an exceptionally 
long paragraph on the topic starting on page 313 and ending on 316.   The point 
of this little foray on the different causes is not to argue for big 
metaphysical conclusions.  He's made those arguments elsewhere.  And, he says 
as much:  “Yet I refuse to enter here upon a metaphysical discussion.”  (EP, )

As he points out in the opening sentence of this paragraph, everything he says 
here is designed to clarify the distinction between a proposition and an 
argument.  His goal, I think, is to illustrate how we should go about 
classifying different acts of cognition (e.g., as an act of interrogating, 
affirming or arguing) and then ascertaining the nature of those acts.  So, the 
question is something like this:  

1)      If the act is one of affirming an assertion, then what is involved in 
affirming that the proposition true?  

Or this:

2)      If the act is one of arguing for a conclusion from a set of premisses, 
then what is involved in affirming that the argument is valid?

He is also asking the question:  How can we put our questions to nature and get 
a reasonable answer?  That is, how can we find out what is really the case?  
These sound like questions of metaphysics, but he is focusing on a set of 
questions that surface in the theory of logic.  Namely, what hypotheses 
concerning the nature of what is real should we adopt for the sake of 
understanding the validity of deductive, inductive and abductive inferences?  
He has argued that we need, for the sake of making valid deductive arguments, 
to adopt a nominal definition of the real.  He sees that induction and 
abduction requiring richer hypotheses concerning the real.

Here are some things that he says about the hypotheses that are required for 
the sake of making valid abductive inferences:  

 “Abduction . . . is the first step of scientific reasoning, as induction is 
the concluding step.
In abduction the consideration of the facts suggests the hypothesis. In 
induction the study of the hypothesis suggests the experiments which bring to 
light the very facts to which the hypothesis had pointed. The mode of 
suggestion by which, in abduction, the facts suggest the hypothesis is by 
resemblance, -- the resemblance of the facts to the consequences of the 
hypothesis.  The mode of suggestion by which in induction the hypothesis 
suggests the facts is by contiguity, -- familiar knowledge that the conditions 
of the hypothesis can be realized in certain experimental ways.

I now proceed to consider what principles should guide us in abduction, or the 
process of choosing a hypothesis. Underlying all such principles there is a 
fundamental and primary abduction, a hypothesis which we must embrace at the 
outset, however destitute of evidentiary support it may be. That hypothesis is 
that the facts in hand admit of rationalization, and of rationalization by us. 
That we must hope they do, for the same reason that a general who has to 
capture a position or see his country ruined, must go on the hypothesis that 
there is some way in which he can and shall capture it. We must be animated by 
that hope concerning the problem we have in hand, whether we extend it to a 
general postulate covering all facts, or not.

We are therefore bound to hope that, although the possible explanations of our 
facts may be strictly innumerable, yet our mind will be able, in some finite 
number of guesses, to guess the sole true explanation of them. That we are 
bound to assume, independently of any evidence that it is true. Animated by 
that hope, we are to proceed to the construction of a hypothesis.” (CP 7.218-19)

Given the fact that the primary subject matter of the “New Elements” essay is 
the normative science of logic, let us ask:  what are the data (i.e., the 
observations) for generating hypotheses in logic and then putting them to the 
test?  As we seek an answer the question, I believe that we need to focus our 
attention on the “data” part of the equation.  As he says, “the logician has to 
be recurring to reexamination of the phenomena all along the course of his 
investigations.” (EP, 311)

In the paragraphs leading up to his remarks about atomic weights, he considers 
the following examples:  a psychologist studying the experience of déjà vu, a 
logician studying of the experience of similarity and resemblance, a seamstress 
buying fabric from a shopkeeper, a homeowner buying a piece of furniture, and a 
chemist studying the weight of gold.  What is the point of these examples?  
Much of Peirce’s attention is fastened on the question of how we should arrive 
at a more scientific understanding of the conditions for making measurements.  
How should we measure a psychological feeling, or a length of silk, or a the 
size of a piece of furniture, or the chemical weight of an element—or the 
degree to which one feeling (or other idea) is, logically speaking, similar to 
an another. 

In some “comments on “The Basis of Pragmatism in the Normative Sciences,” I 
forwarded the claim that Peirce’s phenomenology is, at least in part, an 
attempt to answer the following question:  what are the formal features in 
experience that are necessary for us to draw valid synthetic inferences from 
our observations?  This is not an easy question to answer.  We’re looking for 
an answer because we want to understand how it is possible to put the qualities 
we’ve observed in a transitive ordering and make comparisons based on the 
degree to one resembles or does not resemble another.  I’d like to add the 
following to what I’ve said thus far:  discovering the formal conditions for 
putting things in such a transitive order and comparing them are essential 
aspects of what is needed to measure them.

The point he is making about using a yard stick to measure length is analogous 
to the point he is making about using a standard for measuring the chemical 
weight of gold.  In order to make measurements of length, we use something that 
is like a rigid bar that can be moved up and down the thing we are measuring 
(so that the finite length of the bar does not matter for purposes of making 
the measurements).  The remark that caught my attention is where he says that 
our theory of measurement is based on the idea that we need something that can 
serve as a more universal standard.  In an effort to make our standard more 
universal, scientists have designated one particular bar in Westminster as the 
object to which our concept of yard refers.  In order to determine whether or 
not any other yardstick we might use will lead us into error, we can—as a 
matter of principle—compare it to the protypical standard in Westminster.

Is this the best way to fix the reference for the concept of a yard?  Peirce 
thinks it is not the best way to remove some of the errors that will crop up in 
the process of making measurements of length.  Instead of relying on a single 
prototype sitting in a case in Westminster, we should rely on an average taken 
from a number of different bars made of different materials and kept under 
different conditions (e.g., at different ranges of temperature).  We use the 
concept of yard in such a way that it refers to the mean length of them all.  
This is the same kind of thing that a biologist does when she compares a number 
of different specimens and draws up a conception of a “type-specimen” as a kind 
of typical thing that has a normal size and shape.  

What is the weight of gold?  In saying that it is an elementary chemical 
substance having a particular atomic weight of about 197 ¼, we are relying upon 
some kind of standard in making the comparison.  The standard, of course, is 
the atomic weight of hydrogen, which is taken to have a weight of 1.  What is 
it to say that the weight of hydrogen is 1 unit?  His answer is that, in 
comparison to air, it is about 14 ½ times lighter. 

In this passage, is Peirce making some kind of metaphysical point about the 
deeper “logic” of the chemical elements?  I don’t think so.  Rather, he is 
making a point about what is needed to make comparisons between things—and then 
he is asking what is needed to set up a standard for measuring those things.  
The system of measurement set up by Dalton in 1803 was a relative scale that 
used the weight of hydrogen as the base unit.  Technically speaking, scientists 
could say that the mass of hydrogen was exactly one only because it was the 
serving as the base unit of measurement in a relative scale.  It would not 
serve the goals of the scientists to say that the concept of the weight of 
hydrogen refers to protypical sample stored in a glass case in Westminster.  
Rather, the weight of hydrogen, like the length of a yard, should be taken to 
refer to a mean over many observations of the relative weights of gold, carbon, 
hydrogen and other elements.

What does this have to do with the normative theory of logic?  I believe that 
it bears on logic in two ways.  First, I believe that an analysis of the things 
we observe—in chemistry, biology, the selling of fabric, etc.—requires us to 
examine the underlying grounds for making measurements of the various 
phenomena.  We can draw on mathematics, phenomenology and logic in order to 
deepen our understanding of what is necessary to apply one or another kind of 
measurement to a given kind of phenomena that has been observed in one or 
another of the practical or theoretical sciences.   Second, this kind of 
question surfaces when we ask what the standards are for analyzing the 
phenomena we’re drawing on in the theory of logic.  Peirce says as much in his 
discussion of what is needed to make something as simple as a comparison 
between two qualities of feeling.  Take, for instance, a comparison between two 
experiences of the color of blue.  In the hospital room where I’m sitting with 
my daughter, there is a stool and a sheet that have just about the same hue.  
From this point on, I will probably refer to this shade of color as “hospital 
blue.”  When I compare the intensity of the color I experience when looking at 
the stool with the color I experience when looking at the sheet, it seems to me 
that the color of the stool is remarkably more intense than the color of the 
sheet.  The two objects are across the room from each other, so all I can do is 
to compare the intensity of the one with my memory of the intensity of the 
other.  What are my grounds for making such a comparison?

One of the points Peirce is making at this point in subsection 4 is that the 
comparison of the intensity of two experiences of the quality of blue is 
something that is “measured chiefly by aftereffects.” (EP, 320) He is laboring 
over this point, I believe, because he is keenly interested in set of related 
issues.  Consider, for instance, the following questions:

1)      What is the standard that we can use when comparing the feeling that an 
argument is a good inference to the feeling that an argument is an invalid 
inference?  Isn’t this similar in some respects to comparing the intensity of a 
one experience of a feeling of blue to another feeling of blue?  Isn’t it 
different in other respects? 

2)      Once we have formed a class of sample arguments that we take to be good 
and a class that we take to be bad, what kind of measurements can be made when 
comparing these classes?  At the very least, we can apply a nominal scale in 
saying that they are labeled as different classes.  For the sake of the logical 
theory, however, we need a stronger standard of measurement, don’t we?

3)      What is the standard for making the comparison of the goodness or 
badness of an argument?  Should we take it to be a prototypical argument that 
appears to be beyond criticism?  Perhaps we should take an argument, such as a 
cogito argument, or an ontological argument for God’s reality, or an argument 
for the indubitability of the axioms of logic as a prototype, and then place 
one or another of these arguments in a glass case in Westminster.  I suspect 
that this would fail to serve the purpose we have in removing possible errors 
from our measurements of the goodness or badness of any given argument.

How can the examples of measuring silk against a yardstick, comparing 
biological specimens to a “type-specimen”, and comparing the weight of carbon 
and gold to hydrogen help us think more clearly about the grounds we having for 
comparing arguments and saying that one class contains a sample of good 
inferences and that another class contains a sample of bad inferences.  In 
making such comparisons, we need something more than just a nominal assignment 
of the term ‘good’ to one class and ‘bad’ to another.  Having said that, don’t 
we need more than an ordinal scale that enables us to make relative comparisons 
of goodness and badness?  How might we arrive in our theory of logic at a 
standard of measuring the validity of inferences that is richer than a nominal 
or ordinal scale?  After all, we are relying on our standards for comparing 
arguments for the sake of arriving at conclusions about what, really, is true 
and false.

These are the kinds of questions that I’m particularly interested in trying to 
answer.  My hunch is that, rabbit hole or not, Peirce is pointing us to the 
resources needed to answer these kinds of questions.  As he points us in a 
specific direction, however, he is assuming that we will "actively think" and 
draw on his sentences as "so many blazes to enable him to follow the track of 
the reader's thought."   The real danger is not one of following the blazes and 
heading down the rabbit hole.  Rather, it is one of sticking with our personal 
assumptions and convictions in such a fashion that we make ourselves impervious 
to the fruitful suggestions that are around us and, in doing so, fail to see 
that we are sitting in a hole of our own making with no sense of which 
direction is up and which is down. 

That, at least, is my abiding worry.  Hopefully, it is one that will spur me to 
active inquiry.

theory

Dear Jeff:

Thank you for your exposition on your views on the relations between material 
and formal categories.
(From your post below)
First off, if things are sounding mystical to your ears, I hope it is a by 
product of the richness of the ideas Peirce is examining--and not a by-product 
of the comments I'm offering.

Your hopefulness is partially realized. And partially not.

Your may recall Clark’s perceptive’s postings from Kainia Stoichia on CSP views 
on causality. In subsequent sentences, CSP gives a crisp example of his 
deductions about relations between gold (as a relative weight) when compared to 
hydrogen and then to air.
"What is gold? It is an elementary substance having an atomic weight of about 
197¼. In saying that it is elementary, we mean undecomposable in the present 
state of chemistry, which can only be recognized by real reactional experience. 
In saying that its atomic weight is 197¼, we mean that it is so compared with 
hydrogen. What, then, is hydrogen? It is an elementary gas 14¼ times as light 
as air. And what is air? Why, it is this with which we have reactional 
experience about us. The reader may try instances of his own until no doubt 
remains in regard to symbols of things experienced, that they are always 
denotative through indices; such proof will be far surer than any apodictic 
demonstration.  From KS.

This crisp example of material and formal categories (and the logical phenomena 
inferred by mathematics) about material categories is worthy of careful study.  
He presents a logic of relatives. Classification of categories inevitably 
brings forth issues of causality, Aristotelian or otherwise, which he 
illustrates.  You may find it useful to contrast this example with other direct 
examples from biology or medicine as you pursue your thinking about these 
matters.

My personal feeling about your exposition is that such a view of material and 
formal categories leads one into an extra-ordinarily deep philosophical morass 
from which you may never emerge.  For me, the choice of rhetorical terms in 
your exposition leads not to calculations but to a Luciferic network of 
semantic entanglements.

Thanks again for clarifying your thoughts.

Cheers

Jerry

Hi Jerry, List,

First off, if things are sounding mystical to your ears, I hope it is a by 
product of the richness of the ideas Peirce is examining--and not a by-product 
of the comments I'm offering.

To a large degree, the answers to the questions you are trying to raise are 
going to be found in the larger story that is articulated in the theory of 
semiotics.  At this point, I am trying to offer some comments on some of 
Peirce's explanations and definitions as a kind of run up to the 
phenomenological categories--and especially the distinction between the formal 
and material aspects of those categories.  The general suggestion I'm making is 
that Peirce is not providing two entirely separate lists of the categories, one 
formal and that other material. Rather, there is a close connection between the 
two even if they do not, in experience, match perfectly because our experience 
of the material categories of quality, brute fact and mediation is always so 
richly complex.  My general suggestion may seem controversial because some 
interpreters seem to be offering a different reading of the relevant texts.

Confining myself to the subject of the phenomenological categories and the role 
of mathematics in informing our understanding of the essential formal elements 
of the monad, dyad and triad, I do take Peirce to be offering an account of the 
elements needed for setting up the frameworks necessary for referring to 
grounds, objects and interpretants.  One might call them three interrelated 
"frames of reference."

What do the signs that we use in mathematics refer to?  Much depends upon 
whether we are using the signs to seeks answer to questions in pure or applied 
mathematics.  Let's consider the case of pure mathematics.  What do the signs 
used in topology refer to?  In the account he offers in the New Elements, the 
key operations for setting up a system of mathematical diagrams are those of 
generation and intersection.  These are the operations used to generate a line 
by moving a particle from a point, or for determining the location of a point 
on a line by intersecting it with another line.

As we try to understand the conditions that make it possible for the different 
representations to refer, we'll need to be clear in identifying the 
representations we're talking about.  It is one thing to ask:  what does that 
particle in the diagram that is being moved refer to?  It is another thing to 
ask, what does the symbol "particle" refer to?  I hope it is clear that the 
conditions under which the symbol "particle" refers is dependent, in many 
respects, on the conditions under which the iconic particle that is draw on the 
page is able to refer.  As a hypo-icon, the particle we move as we draw the 
line is remarkably rich as a sign.  At any time in the act of drawing the line 
on the paper, there are qualisigns, sinsigns and legisigns working together so 
that the particle can function as a rich sign complex in a larger process of 
interpretation.  What is more, the particle embodies the idea of a generator. 
That is, it embodies a more general rule that determines how we might generate 
innumerable other possible lines from the point.  This is a more general rule 
that enables us to interpret the larger mathematical space in which the line is 
being constructed.  It enables us to understand how one line my be transformed 
continuously to give us a line that is homeomorphic with the first, or how 
various kinds of discontinuities might be introduced to give us another 
different line altogether.

I hope you can see that I'm trying to bracket some of the questions you've 
raised about the role of real things (i.e., chemical compounds, protein or DNA 
molecules, and the like) in serving as the grounds or objects to which one or 
another kind of representation might refer.  I'm bracketing those questions for 
a reason.  I'd like to keep the phenomenological analysis of the conditions 
under which the signs used in pure mathematics refer free from big metaphysical 
assumptions about what is really the case as a positive matter of fact.  There 
is a long line of philosophers who have tried to import such metaphysical 
assumptions into their accounts of the reference and meaning of the signs used 
in math and formal logic (e.g., Mill, Quine, etc.), but Peirce is resisting 
this move--at least until we're ready to address questions in metaphysics.  
Once we are ready and we're using the methods appropriate for answering 
questions in metaphysics, we'll need to think about the real nature of an ideal 
system of mathematical definitions, hypotheses, theorems, etc., and what it is 
for that system to be real as a rich and consistent network of possible formal 
relations.

Jeffrey:

Your posts become increasingly mystical.

This is not a judgement, merely an observation from a philosophy of mathematics 
perspective.

At issue is how to you assign meaning to mathematical symbols.
In particular, in light of K.S. and his comments on the meaning of number in 
the context of his description of gold?

More to the point, does the meaning of mathematical symbols reside in 
mathematics itself or do the meanings refer to the reference systems for the 
symbol system, that is the application to a particular material reality, such 
as the atomic numbers?  Or the sequence numbers for a genetic sequence? Or 
protein sequence?
In yet other terms, does the concept of order infer a universal meaning or a 
meaning dependent on the nouns of the copulative proposition?

Perhaps you can address these vexing issue?

Cheers

Gary F., Gary R., List,

In an effort to think a bit more about the form/matter distinction as it 
applies to the phenomenological categories, let me add few comments about an 
explanation that Peirce provides concerning the mathematical form of a state of 
things.  I'd like to add some remarks about this explanation because I think it 
offers us a nice way of responding to a concern Gary F. raised.  Here is the 
concern:

Gary F. says:  "Jeff, I’m interested in your question, 'is there any kind of 
formal relation between the parts of a figure, image, diagram (i.e., any 
hypoicon) that does not have the form of a monad, dyad or triad?' . . . I 
confess that I have no idea how we would go about investigating that question."

My initial response was:  "The answer to the question involves the whole of 
Peirce's semiotic--and not just his account of the iconic function of signs.  
So Peirce is bringing quite a lot to bear on the question.  For starters, 
however, I think we should consider the examples he thinks are most important 
in formulating an answer. What Peirce sees is that, in mathematics, the 
examples we need are as 'plenty as blackberries' in the late summer.  (CP 
5.483)  What do you know, it is late August.  Let's go picking."

As a first stop on our way to the briar patch, let's consider the following 
definition from "The Basis of Pragmaticism in the Normative Sciences."

"A mathematical form of a state of things is such a representation of that 
state of things as represents only the samenesses and diversities involved in 
that state of things, without definitely qualifying the subjects of the 
samenesses and diversities.  It represents not necessarily all of these; but if 
it does represent all, it is the complete mathematical form. Every mathematical 
form of a state of things is the complete mathematical form of some state of 
things. The complete mathematical form of any state of things, real or 
fictitious, represents every ingredient of that state of things except the 
qualities of feeling connected with it. It represents whatever importance or 
significance those qualities may have; but the qualities themselves it does not 
represent." (EP, vol. 2, 378)

Peirce suggests that this explanation is "almost self-evident."  At this point 
in his discussion, however, he merely ventures the explanation as a "private 
opinion."  I cite this passage because it bears directly on the question of how 
our understanding of the mathematical form of something such as a figure or 
diagram is supposed to inform our understanding of the formal categories of 
monad, dyad and triad (or, firstness, secondness, thirdness)--and how we might 
use those categories in performing a phenomenological analysis of something 
that has been observed.

Peirce says that he has introduced this explanation in order to account for the 
emphatic dualism we find in the normative sciences.  The dualism is especially 
marked in logic and ethics (e.g., true and false, valid and invalid, right and 
wrong, good and bad), but it is also found in aesthetics.  As such, he is 
noticing a phenomena that has been widely observed to be a part of our common 
experience in thinking about how we ought to act and think, and he is getting 
ready to venture a hypothesis to explain what is surprising about the 
phenomena. The explanation of the dualism that follows might seem a bit hard to 
make out, but I think it is clear that this is what he is trying to do.

That might have seemed a bit opaque, so let me try to restate the point.  I 
think Peirce is drawing on an understanding of mathematical form for the sake 
of performing an analysis of a particular phenomenon that calls out for 
explanation.  We need to see what it is in the phenomena (i.e., the dualism in 
the normative sciences) that really calls out for explanation.  Otherwise, we 
will not have a clear sense of whether one or another hypothesis is adequate or 
inadequate to explain what needs to be explained.

He says the following about his account of the mathematical form of a state of 
a things:  "Should the reader become convinced that the importance of 
everything resides entirely in its mathematical form, he too, will come to 
regard this dualism as worthy of close attention?"

Why does Peirce say that the importance of everything resides in its 
mathematical form?  On my reading of this passage and what follows in the next 
several pages of the essay, I think he is developing the claim I asserted 
above.  That is, every kind of formal relation that might be found between the 
parts of a figure, image, diagram and the space in which such things are 
constructed must have the form of what we are calling, in our phenomenological 
theory, a monad, dyad or triad.

It might sound ridiculous to suggest that the dualism present in our experience 
of what is valid or invalid as a reasoning or what is right or wrong as an 
action can be clarified by using a mathematical diagram, such as a drawing on a 
piece of paper of two dots that we might count by saying "one' and "two," but 
he says that we shouldn't disregard such a suggestion.  He has argued elsewhere 
that every observation we might make must involve some kind of figure or 
diagram--and the form of such a figure or diagram can be understood in terms of 
having the structure of a skeleton set (CP, 7.420-32), or a network figure (CP, 
6.211), or some other kind of really basic mathematical structure.  I refer to 
those particular mathematical structures because the first can be applied to 
things in our experience that are more discrete in character, and the second 
can placed over things more continuous in character.
