, the original name, which had been used in a manner he did not approve of in the "literary journals". Peirce in 1905 announced his coinage "pragmaticism", saying that it was "ugly enough to be safe from kidnappers" (Collected Papers (CP) 5.414). Today, outside of philosophy, "pragmatism" is often taken to refer to a compromise of aims or principles, even a ruthless search for mercenary advantage. Peirce gave other or more specific reasons for the distinction in a surviving draft letter that year and in later writings. Peirce's pragmatism, that is, pragmaticism, differed in Peirce's view from other pragmatisms by its commitments to the spirit of strict logic, the immutability of truth, the reality of infinity, and the difference between (1) actively willing to control thought, to doubt, to weigh reasons, and (2) willing not to exert the will, willing to believe. In his view his pragmatism is, strictly speaking, not itself a whole philosophy, but instead a general method for the clarification of ideas. He first publicly formulated his pragmatism as an aspect of scientific logic along with principles of statistics

The clarification of ideas in inquiry

Pragmatism starts with the idea that belief is that upon which one is prepared to act. Peirce's pragmatism is about conceptions of objects. His pragmatism is a method for fruitfully sorting out conceptual confusions caused, for example, by distinctions that make (sometimes needful) formal yet not practical differences. It equates any conception of an object with a conception of that object's effects to a general extent of those conceived effects' conceivable implications for informed practice. Those conceivable practical implications are the conception's meaning. The meaning is the consequent form of conduct or practice that would be implied by accepting the conception as true. Peirce's pragmaticism, in the strict sense, is about the conceptual elucidation of conceptions into such meanings — about how to make our ideas clear. Making them true, in the sense of proving and bearing them out in fruitful practice, goes beyond that. A conception's truth is its correspondence to the real, to that which would be found by investigation taken far enough. A conception's actual confirmation (if it occurs) is neither its meaning nor its truth per se, but an actual upshot.

In "How to Make Our Ideas Clear", Peirce discusses three grades of clearness of conception:
1. Clearness of a conception familiar and readily used even if unanalyzed and undeveloped.
2. Clearness of a conception in virtue of clearness of its definition's parts, in virtue of which logicians called an idea distinct, that is, clarified by analysis of just what elements make the given idea applicable. Elsewhere, echoing Kant, Peirce calls such a definition "nominal" (CP 5.553).
3. Clearness in virtue of clearness of conceivable practical implications of the object's effects as conceived of, such as can lead to fruitful reasoning, especially on difficult problems. Here he introduces that which he later called the pragmatic maxim

.


By way of example of how to clarify conceptions, he addressed conceptions about truth and the real as questions of the presuppositions of reasoning in general. To reason is to presuppose (and at least to hope), as a principle of the reasoner's self-regulation, that the truth is independent of our vagaries of opinion and is discoverable. In clearness's second grade (the "nominal" grade), he defines truth as the correspondence of a sign (in particular, a proposition) to its object, and the real as the object (be it a possibility or quality, or an actuality or brute fact, or a necessity or norm or law) to which a true sign corresponds, such that truth and the real are independent of that which you or I or any actual, definite community of inquirers

 think. After that needful but confined step, next in clearness's third grade (the pragmatic, practice-oriented grade) he defines truth — not as actual consensus, such that to inquire would be to poll the experts — but as that which would be reached, sooner or later but still inevitably, by research taken far enough, such that the real does depend on that ideal final opinion—a dependence to which he appeals in theoretical arguments elsewhere, for instance for the long-run validity of the rule of induction. (Peirce held that one cannot have absolute theoretical assurance of having actually reached the truth, and later said that the confession of inaccuracy and one-sidedness is an essential ingredient of a true abstract statement.) Peirce argues that even to argue against the independence and discoverability of truth and the real is to presuppose that there is, about that very question under argument, a truth with just such independence and discoverability. For more on Peirce's theory of truth, see the Peirce section in Pragmatic theory of truth. Peirce's discussions and definitions of truth have influenced several epistemic truth theorists and been used as foil for deflationary

 theories of truth.

Peirce said that a conception's meaning consists in "all general modes of rational conduct" implied by "acceptance" of the conception—that is, if one were to accept, first of all, the conception as true, then what could one conceive to be consequent general modes of rational conduct by all who accept the conception as true?—the whole of such consequent general modes is the whole meaning. His pragmatism, since a conception is general, does not equate a conception's meaning, its intellectual purport, with any definite set of actual consequences or upshots corroborating or undermining the conception or its worth, nor does it equate its meaning, much less its truth (if it is true), with the conceived or actual benefit or cost of the conception itself, like a meme (or, say, propaganda), outside the perspective of its being true in what it purports. If it is true, its truth is not transitory but instead immutable and independent of actual trends of opinion. His pragmatism also bears no resemblance to "vulgar" pragmatism, which misleadingly connotes a ruthless and Machiavellian search for mercenary or political advantage. Rather, Peirce's pragmatic maxim is the heart of his pragmatism as a method of experimentational mental reflection arriving at conceptions in terms of conceivable confirmatory and disconfirmatory circumstances—a method hospitable to the generation of explanatory hypotheses, and conducive to the employment and improvement of verification to test the truth of putative knowledge.

Peirce's pragmatism, as method and theory of definitions and the clearness of ideas, is a department within his theory of inquiry, which he variously called "Methodeutic" and "Philosophical or Speculative Rhetoric". He applied his pragmatism as a method throughout his work.

Peirce called his pragmatism "the logic of abduction

A theory that proves itself more successful than its rivals in predicting and controlling our world is said to be nearer the truth. This is an operational notion of truth employed by scientists.

In "The Fixation of Belief", Peirce characterized inquiry in general not as the pursuit of truth per se but as the struggle to settle disturbances or conflicts of belief, irritating, inhibitory doubts, belief being that on which one is willing to act. That let Peirce frame scientific inquiry not only as a special kind of inquiry in a broader spectrum, but also, like inquiry generally, as based on actual doubts, not mere verbal doubts (such as hyperbolic doubt), which he held to be fruitless, and it let him also frame it, by the same stroke, as requiring that proof rest on propositions free from actual doubt, rather than on ultimate and absolutely indubitable propositions. He outlined four methods, ordered from least to most successful in achieving a secure fixation of belief:
  1. The method of tenacity (policy of sticking to initial belief) — which brings comforts and decisiveness, but leads to trying to ignore contrary information and others' views, as if truth were intrinsically private, not public. The method goes against the social impulse and easily falters since one may well fail to avoid noticing when another's opinion is as good as one's own initial opinion. Its successes can be brilliant but tend to be transitory.
  2. The method of authority — which overcomes disagreements but sometimes brutally. Its successes can be majestic and long-lasting, but it cannot regulate people thoroughly enough to suppress doubts indefinitely, especially when people learn about other societies present and past.
  3. The method of congruity or the a priori or the dilettante or "what is agreeable to reason" — which promotes conformity less brutally, but depends on taste and fashion in paradigm
    Paradigm
    The word paradigm has been used in science to describe distinct concepts. It comes from Greek "παράδειγμα" , "pattern, example, sample" from the verb "παραδείκνυμι" , "exhibit, represent, expose" and that from "παρά" , "beside, beyond" + "δείκνυμι" , "to show, to point out".The original Greek...

    s and can lead in circles over time, along with barren disputation. It is more intellectual and respectable but, like the first two methods, sustains capricious and accidental beliefs, destining some minds to doubts.
  4. The method of science — the only one whereby inquiry can, by its own account, go wrong (fallibilism
    Fallibilism
    Fallibilism is the philosophical principle that human beings could be wrong about their beliefs, expectations, or their understanding of the world...

    ), and purposely tests itself and criticizes, corrects, and improves itself.


Peirce held that, in practical affairs, slow and stumbling ratiocination is often dangerously inferior to instinct and traditional sentiment, and that the scientific method is best suited to theoretical research, which in turn should not be bound to the other methods and to practical ends; reason's "first rule" is that, in order to learn, one must desire to learn and, as a corollary, must not block the way of inquiry. What recommends the scientific method of inquiry above all others is that it is deliberately designed to arrive, eventually, at the ultimately most secure beliefs, upon which the most successful practices can eventually be based. Starting from the idea that people seek not truth per se but instead to subdue irritating, inhibitory doubt, Peirce shows how, through the struggle, some can come to submit to truth, seek as truth the guidance of potential practice correctly to its given goal, and wed themselves to the scientific method.

Pragmaticism's name

It is sometimes stated that James' and other philosophers' use of the word pragmatism so dismayed Peirce that he renamed his own variant pragmaticism. Susan Haack

 has disagreed, pointing out the context in which Peirce publicly introduced the latter term in 1905. Haack's excerpt of Peirce begins below at the words "But at present...," and continues with some ellipses. The fuller excerpt below supports her case further:
Then, in a surviving draft letter to Calderoni, dated by the CP editors as circa that same year 1905, Peirce said regarding his above-quoted discussion:

Indeed in the Monist article Peirce had said that the coinage "pragmaticism" was intended "to serve the precise purpose of expressing the original definition". Of course this does not mean that Peirce regarded his fellow pragmatist philosophers as word-kidnappers. To the contrary he had said, regarding James's and Schiller's uses of the word "pragmatism": "So far, all went happily." So it would seem that Peirce intended the coinage "pragmaticism" for two distinguishable purposes: (1) protection from literary journals and word-kidnappers, and (2) reference strictly to his own form of pragmatism, as opposed even to other pragmatisms that had not moved him to the new name. In the letter to Calderoni, Peirce did not reject all significant affiliation with fellow pragmatists, and instead said "the rest of us". Nor did he reject all such affiliation in later discussions.

However, in the following year 1906, in a manuscript "A Sketch of Logical Critics", Peirce wrote:

(Peirce proceeded to criticize J. S. Mill but acknowledged probable aid from Mill's Examination.)

Then, in 1908, in his article "A Neglected Argument for the Reality of God", mentioning both James and the journalist, pragmatist, and literary author Giovanni Papini
Giovanni Papini
Giovanni Papini was an Italian journalist, essayist, literary critic, poet, and novelist.-Early life:...

, Peirce wrote:
In 1871, in a Metaphysical Club in Cambridge, Mass., I used to preach this principle as a sort of logical gospel, representing the unformulated method followed by Berkeley, and in conversation about it I called it "Pragmatism." In December 1877 and January 1878 I set forth the doctrine in the Popular Science Monthly, and the two parts of my essay were printed in French in the Revue Philosophique, volumes vi. and vii. Of course, the doctrine attracted no particular attention, for, as I had remarked in my opening sentence, very few people care for logic. But in 1897 Professor James remodelled the matter, and transmogrified it into a doctrine of philosophy, some parts of which I highly approved, while other and more prominent parts I regarded, and still regard, as opposed to sound logic. About the time Professor Papini discovered, to the delight of the Pragmatist school, that this doctrine was incapable of definition, which would certainly seem to distinguish it from every other doctrine in whatever branch of science, I was coming to the conclusion that my poor little maxim should be called by another name; and accordingly, in April 1905, I renamed it Pragmaticism.


Peirce proceeded in "A Neglected Argument" to express both deep satisfaction and deep dismay with his fellow pragmatists. He singled F.C.S. Schiller

 out by name and was vague about which among the others he most particularly referred to. Peirce wrote "It seems to me a pity they should allow a philosophy so instinct with life to become infected with seeds of death...."
Peirce remained allied with them about:
  • the reality of generals and habits, to be understood, as are hypostatic abstraction

    s, in terms of potential concrete effects even if unactualized;
  • the falsity of necessitarianism;
  • the character of consciousness as only "visceral or other external sensation".
but was dismayed with their "angry hatred of strict logic" and saw seeds of philosophical death in:
  • their view that "truth is mutable";
  • their view that infinity is unreal; and
  • "such confusions of thought as of active willing (willing to control thought, to doubt, and to weigh reasons) with willing not to exert the will (willing to believe)".

  • There has been some controversy over Peirce's relation to other pragmatists over the years and over the question of what is owed to Peirce, with visible crests in titles such as literary essayist Edward Dahlberg
    Edward Dahlberg

    , that of Achilles and the Tortoise, in terms of James's and others' difficulties with it. Peirce therein expressed regret at having used a "contemptuous" manner about such difficulties in his 1903 Harvard lectures on pragmatism (which James had arranged), and said of James, who had died in August 1910: "Nobody has a better right to testify to the morality of his attitude toward his own thoughts than I, who knew and loved him for forty-nine or fifty years. But owing to his almost unexampled incapacity for mathematical thought, combined with intense hatred for logic — probably for its pedantry, its insistence on minute exactitude — the gêne of its barbarous formulations, etc. rendered him an easy victim to Zeno and the Achilles....", called James "about as perfect a lover of truth as it is possible for a man to be...." and said: "In speaking, then, of William James as I do, I am saying the most that I could of any man's intellectual morality; and with him this was but one of a whole diadem of virtues."
