Corcoran, J. 2007. Psychologism. American Philosophy: an Encyclopedia. Eds. John Lachs and Robert Talisse. New York: Routledge. Pages 628-9. -/- Psychologism with respect to a given branch of knowledge, in the broadest neutral sense, is the view that the branch is ultimately reducible to, or at least is essentially dependent on, psychology. The parallel with logicism is incomplete. Logicism with respect to a given branch of knowledge is the view that the branch is ultimately reducible to logic. Every branch of (...) knowledge depends on logic. Psychologism is found in several fields including history, political science, economics, ethics, epistemology, linguistics, aesthetics, mathematics, and logic. Logicism is found mainly in branches of mathematics: number theory, analysis, and, more rarely, geometry. Although the ambiguous term ‘psychologism’ has senses with entirely descriptive connotations, it is widely used in senses that are derogatory. No writers with any appreciation of this point will label their own views as psychologistic. It is usually used pejoratively by people who disapprove of psychologism. The term ‘scientism’ is similar in that it too has both pejorative and descriptive senses but its descriptive senses are rarely used any more. It is almost a law of linguistics that the negative connotations tend to drive out the neutral and the positive. Dictionaries sometimes mark both words with a usage label such as “Usually disparaging”. In this article, the word is used descriptively mainly because there are many psychologistic views that are perfectly respectable and even endorsed by people who would be offended to have their views labeled psychologism. A person who subscribes to logicism is called a logicist, but there is no standard word for a person who subscribes to psychologism. ‘Psychologist’, which is not suitable, occurs in this sense. ‘Psychologician’, with stress on the second syllable as in ‘psychologist’, has been proposed. In the last century, some of the most prominent forms of psychologism pertained to logic; the rest of this article treats only such forms. Psychologism in logic is very “natural”. After all, logic studies reasoning, which is done by the mind, whose nature and functioning is studied in psychology—using the word ‘psychology’ in its broadest etymological sense. (shrink)

The present paper deals thus with some fundamental agreements and disagreements between Peirce and James, on crucial issues such as perception and consciousness. When Peirce first read the Principles, he was sketching his theory of the categories, testing its applications in many fields of knowledge, and many investigations were launched, concerning indexicals, diagrams, growth and development. James's utterances led Peirce to make his own views clearer on a wide range of topics that go to the heart of the foundations of (...) psychology and that involve the relationship between perception and logic, between consciousness and the categories, between abstraction and the 'stream of thought'. The idea is to show that Peirce detected important discoveries and insights in the Principles, but felt that James could not make proper use of them because of logical confusions, and also because of his "clandestine" metaphysics. The point in this essay is thus not to look for remains of psychologism in Peirce's writings,13 but to look at Peirce's comments about James's psychology in an attempt to identify where and why Peirce amended James's views. Since the project to provide some insight on Peirce's extensive reading ofJames's Principles of Psycho/.ogy would deserve a full volume, I shall focus here on three occasions where Peirce explicidy commented on Jarnes's Principles. In the first section, I shall consider bis assessment of James's chapter on space, which was published as a series of articles in 1887, in Mind. I shall then turn to the 1891 review of the Principles in The Nation for important complements on perception as inference. In the third section, I shall deal with Peirce's manuscript "Questions on James's Principles"(Rl099). These "Questions" reveal a deep interest in psychological problems and suggest different ways along which Peirce's new advances in the field of the categories, of continuity, and abstraction could provide a proper basis for the philosophy of mind.

Charles Sanders Peirce was acknowledged by William James as the founder of pragmatism; however, while James’ appreciation for psychology is well taken into account in his philosophy, the role that psychological inquiry played in Peirce’s thought remains largely unexplored. Few excellent studies indicate Peirce as the first American experimental psychologist (Cadwallader 1974, 1975; Fisch 1986) and as the first to perform a truly modern experiment in psycho-physics (Hacking 1988). Nonetheless, Peirce’s commitment to psycho-physics fails to be fully integrated with the (...) broader project of his philosophy. This integration is crucial to gain a better understanding of the complexity of Peirce’s system of thought and of his position in the psychologistic-antipsychologistic divide. On the logical side, making Peirce’s position on psychology explicit leads to investigating his material logic; on the psychological side, Peirce’s scientific approach to psychology has its theoretical foundation in Kant and further marks the distinction between Peirce’s pragmatism and James’.

Kelly suggested that it was useful to consider anyone as functioning as a scientist, in the business of applying theories, making hypotheses and predictions and testing them out in the practice of everyday life. One of Charles Peirce’s major contributions was to develop the disciplines of logic and the philosophy of science. We can deepen and enrich our understanding of Kelly’s vision by looking at what Peirce has to say about the process of science. For Peirce, the essence of science (...) was the application of the laws of inference. He developed a much broader concept of logic, elaborating the processes of deduction and induction and adding to these the logic of hypothetical inference, or ‘abduction’, even as Kelly broadened it further in his “departure from classical logic”. Examining the implications of these three forms of inference allows us to elaborate the dynamics involved in the process of construing, ordinacy and the cycles of experience, creativity and decision making. This is the second of a three part series examining the relationship between the work of Peirce and Kelly. The third will include a look at phenomenology, bipolarity, the self, dialogical process and sociological considerations. (shrink)

This essay discusses Peirce’s appeal to logical machines as an argument against psychologism. It also contends that some of Peirce’s anti-psychologistic remarks on logic contain interesting premonitions arising from his perception of the asymmetry of proof complexity in monadic and relational logical calculi that were only given full formulation and explication in the early twentieth century through Church’s Theorem and Hilbert’s broad-ranging Entscheidungsproblem.

The main purpose of this article is, from a semiotic perspective, arguing for the recognizing of a semantic role of the imagination as a necessary condition to our linguistic experience, regarded as an essential feature of the relations of our thought with the world through signification processes ; processes centered in but not reducible to discourse. The text is divided into three parts. The first part presents the traditional position in philosophy and cognitive sciences that had barred until recent times (...) the possibility to investigate the semantic function performed by imagination, mainly due to the anti-psychologist arguments on which it is based. After that, I situate my perspective inside of the recent research panorama in philosophy and cognitive science. The second part presents the semiotic framework on the relation between thought, language, and world, conceived through the concepts of signification processes and sense-conditions. Within this framework, I introduce the concept of linguistic experience, characterizing semantic imagination as one of its sense-conditions. In the third part, several pieces of evidence for corroborating the semantic function of imagination are discussed. These pieces come from the fields of phenomena denoted as diagrammatic thought and counterfactual thought. Diagrammatic thought, briefly discussed, points out the semantic work of imagination in the semi-discursive sign systems constructed in mathematics, logic, and natural science. After defending a widening of the concept of counterfactual thought, and its intrinsic relation with semantic imagination, the role of semantic imagination is briefly discussed in some types of counterfactual thought found in our conceptions of modal concepts, in thought experiments, in apagogical arguments, and in the creative discursive devices.

The aim of the paper is to try and make one’s ideas clearer about such concepts as “logic,” “psychology,” “mind,” “normativity,” rationality,” as they were conceived by Peirce, in order to elucidate his genuine position as far as the relationship between logic and pychology is concerned, whether he was or was not a straightforward “anti psychologist” in logic, and from such analyses, to make some suggestions about the contemporary relevance of Peirce’s original views on such isues.

A variety of commentators have explored the similarities between pragmatism and Thomas Reid’s Philosophy of Common Sense. Peirce himself claims his version of pragmatism either (loosely) is, or entails, a Critical Common-sensism, a blend of what is best in Kant and Reid. In this paper I argue for a neglected aspect of the relation between Peirce and Reid, and of each to common sense: linguistics. First, I summarize Peirce’s account of what distinguishes his common-sensism from Reid’s. Second, I argue for (...) the importance of appeals to linguistic universals by Reid as both a source for identifying common sense beliefs, and a basis for justifying them. While Peirce is occasionally tempted by such appeals, overall he is critical of appeals to language, especially as most Western philosophers have been familiar with a small set of (Indo-)European languages; say, English, French, German, Greek, Italian, and Latin. This leads to the third section, which concerns Peirce’s familiarity with major nineteenth century linguists, and his contention that the ‘peculiarity’ of Western European languages has impeded the development of logic and philosophy. In particular, I look at unpublished manuscripts where Peirce summarizes his own study of non-European languages, ranging from Arabic, to Ngarrindjeri, to Xhosa. Peirce was only an amateur linguist, and also aware of the challenges of doing cross-cultural linguistics through comparative grammar; e.g., the temptation to force unfamiliar languages onto the “Procrustean Bed of Aryan grammar” (CP 2.211). Nonetheless, this study left him suspicious of any claims of linguistic universals, and supported his anti-psychologism. That is, not only should logic and philosophy not be based upon psychology (at least as a special science), they should also be independent of linguistics. However, Peirce also advances something like the so-called Sapir-Whorf hypothesis, that language determines, or at least conditions, thought. The question now becomes what is the nature of a philosophy of common sense, even a critical one, without a common language, or possibly no commonalities across languages? (shrink)
