In other fields of philosophy
Mientras que el pragmatismo comenzó simplemente como un criterio de significado, rápidamente se expandió para convertirse en una epistemología completa con implicaciones de amplio alcance para todo el campo filosófico. Los pragmáticos que trabajan en estos campos comparten una inspiración común, pero su trabajo es diverso.
Philosophy of Science
In the philosophy of science, instrumentalism is the view that concepts and theories are merely useful instruments and progress in science cannot be expressed in terms of concepts and theories that somehow reflect reality. Instrumentalist philosophers often define scientific progress as nothing more than an improvement in the explanation and prediction of phenomena. Instrumentalism does not claim that truth does not matter, but rather provides a specific answer to the question of what truth and falsehood mean and how they function in science.
One of C. I. Lewis's main arguments in Mind and the World Order is: "The outline of a theory of knowledge is that science not only provides a copy of reality, but must work with conceptual systems and that they are chosen for pragmatic reasons, that is, because they aid research. Lewis's own development of multiple modal logics is a good example. Lewis is sometimes called a "conceptual pragmatist" because of this." (Lewis 1929).
Another development is the cooperation of logical positivism and pragmatism in the works of Charles W. Morris and Rudolf Carnap. The influence of pragmatism on these writers is mainly limited to the incorporation of the pragmatic maxim into their epistemology. Pragmatists with a broader conception of the movement often do not refer to them.
W. V. Quine's document "Two Dogmas of Empiricism", published in 1951, is one of the most famous articles in the philosophy of the century in the analytical tradition. The document is an attack on two central tenets of the philosophy of logical positivists. One is the distinction between analytical statements (tautologies and contradictions) whose truth (or falsity) is a function of the meanings of the words in the statement ("all bachelors are not married") and synthetic statements, whose truth (or falsity) is a function of (contingent) states of affairs. The other is reductionism, the theory that every meaningful statement derives its meaning from a logical construction of terms that refers exclusively to immediate experience. Quine's argument brings to mind Peirce's insistence that axioms are not a priori truths but synthetic statements.
Logic
Later in his life, F.C.S. Schiller became famous for his attacks on logic in his textbook, Formal Logic. By then, Schiller's pragmatism had become the closest of any of the classical pragmatists to an ordinary philosophy of language. Schiller sought to undermine the very possibility of formal logic by showing that words only had meaning when used in context. The least famous of Schiller's major works was the constructive sequel to his destructive book Formal Logic. In this sequel, Logic for Use, Schiller attempted to construct a new logic to replace the formal logic he had criticized in Formal Logic. What he offers is something that philosophers would recognize today as a logic that covers the context of discovery and the hypothetico-deductive method.
Considering that F.C.S. Schiller ruled out the possibility of formal logic, most pragmatists are more critical of its claim to ultimate validity and see logic as one tool among others, or perhaps, considering the multitude of formal logics, one set of tools among others. C.S. Peirce developed multiple methods for making formal logic.
Stephen Toulmin's uses of argument inspired scholars in informal logic and rhetorical studies (although it is an epistemological work).
Metaphysics
James and Dewey were empirical thinkers in the most direct way: experience is the definitive proof and experience is what needs to be explained. They were not satisfied with ordinary empiricism because, according to the tradition dating back to Hume, empiricists tended to think that experience was nothing more than individual sensations. For pragmatists, this goes against the spirit of empiricism: we should try to explain everything that occurs in experience, including connections and meaning, rather than explaining them away and positing sense data as the ultimate reality. Radical empiricism, or immediate empiricism in Dewey's words, wants to give a place to meaning and value rather than explaining them as subjective additions to a world of humming atoms.
William James offers an interesting example of this philosophical deficiency:
F. C. S. Schiller's first book, Riddles of the Sphinx, was published before he became aware of the growing pragmatic movement taking place in the United States. In it, Schiller advocates a middle ground between materialism and absolute metaphysics. These opposites are comparable to what William James called hard-minded empiricism and soft-minded rationalism. Schiller argues, on the one hand, that mechanistic naturalism cannot make sense of the "higher" aspects of our world. These include free will, consciousness, purpose, universals and some would add God. On the other hand, abstract metaphysics cannot make sense of the "lower" aspects of our world (e.g., imperfection, change, physicality). While Schiller is vague about the exact kind of middle ground he is trying to establish, he suggests that metaphysics is a tool that can aid investigation, but is only valuable to the extent that it aids in explanation.
In the second half of the century, Stephen Toulmin argued that the need to distinguish between reality and appearance only arises within an explanatory scheme, and therefore that it is pointless to ask what "ultimate reality" consists of. More recently, a similar idea has been suggested by the post-analytic philosopher Daniel Dennett, who argues that anyone who wants to understand the world must recognize both the "syntactic" aspects of reality (i.e., atoms humming) and its emergent or "semantic" properties (i.e., meaning and value).
Radical empiricism gives interesting answers to questions about the limits of science if there are any, the nature of meaning and value, and the viability of reductionism. These questions figure prominently in current debates about the relationship between religion and science, where it is often assumed - although most pragmatists would disagree - that science degrades all that is meaningful into "merely" physical phenomena.
Philosophy of mind
Both John Dewey in Experience and Nature (1929) and half a century later Richard Rorty in his Philosophy and the Mirror of Nature (1979) argued that much of the debate about the relationship of the mind to the body results from conceptual confusions. Instead, they argue that there is no need to place mind as an ontological category.
Pragmatists disagree about whether philosophers should take a quietist or a naturalist stance toward the mind-body problem. The former (Rorty, among them) want to put an end to the problem because they believe it is a pseudo-problem, while the latter believe it is a significant empirical question.
Ethics
Pragmatism sees no fundamental difference between practical and theoretical reason, nor any ontological difference between facts and values. Both facts and values have cognitive content: knowledge is what we must believe; Values are hypotheses about what is good in action. Pragmatic ethics is broadly humanistic because it sees no definitive test of morality beyond what matters to us as humans. Good values are those for which we have good reasons. The pragmatic formulation predates those of other philosophers who have stressed important similarities between values and facts such as Jerome Schneewind and John Searle.
William James attempted to show the significance of (some types of) spirituality, but, like other pragmatists, he did not see religion as the basis of meaning or morality.
William James's contribution to ethics, as presented in his essay The Will to Believe, has often been misunderstood as a plea for relativism or irrationality. In his own terms, he argues that ethics always involves a certain degree of trust or faith and that we cannot always expect adequate evidence when making moral decisions.
Of the classical pragmatists, John Dewey wrote most extensively on morality and democracy. (Edel 1993) In his classic article Three Independent Factors in Morals (Dewey 1930), he tried to integrate three basic philosophical perspectives on morality: right, virtue, and good. He argued that while all three provide meaningful ways of thinking about moral issues, the possibility of conflict between the three elements cannot always be easily resolved. (Anderson, SEP).
Dewey also criticized the dichotomy between means and ends that he considered responsible for the degradation of our daily working and educational lives. He emphasized the need for meaningful work and a conception of education that considered it not as preparation for life but as life itself. (Dewey 2004 [1910] chapter 7, Dewey 1997 [1938], p.47).
Dewey opposed other ethical philosophies of his time, especially the emotivism of Alfred Ayer. Dewey envisioned the possibility of ethics as an experimental discipline, and the values of thought could best be characterized not as feelings or imperatives, but as hypotheses about what actions will lead to satisfactory results or what he called consummatory experience. A further implication of this view is that ethics is a fallible enterprise, since human beings often cannot know what would satisfy them.
During the transition from the 21st century to the 21st century, many accepted pragmatism in the field of bioethics led by philosophers John Lachs and his student Glenn McGee, whose 1997 book "The Perfect Baby: A Pragmatic Approach to Genetic Engineering" (see designer baby) won praise within American classical philosophy and bioethics criticism for its development of a pragmatic theory of bioethics and its rejection of the theory of principalism then in vogue in ethics. medical. An anthology published by The MIT Press, included philosophers' responses to that debate, including Micah Hester, Griffin Trotter, and others, many of whom developed their own theories based on the work of Dewey, Peirce, Royce, and others. Lachs himself developed several applications of pragmatism to bioethics independently of the work of Dewey and James, but expanding on it.
Aesthetics
Art as Experience by John Dewey, based on the William James Lectures he gave at Harvard, was an attempt to show the integrity of art, culture, and everyday experience. Art, for Dewey, is or should be part of everyone's creative life and not just the privilege of a select group of artists. It also emphasizes that the audience is more than a passive recipient. Dewey's treatment of art was a departure from the transcendental approach to aesthetics following Immanuel Kant, who emphasized the uniqueness of art and the disinterested nature of aesthetic appreciation.
A prominent contemporary pragmatic esthetician is Joseph Margolis. He defines a work of art as "a physically embodied, culturally emergent entity", a human "expression" that is not an ontological whim but is in line with other human activity and culture in general. It emphasizes that works of art are complex and difficult to understand, and that no particular interpretation can be given.
Philosophy of religion
Both Dewey and James investigated the role that religion can continue to play in contemporary society, the former in A Common Faith and the latter in The Varieties of Religious Experience.
From a general point of view, for William James, something is true only to the extent that it works. Therefore, the claim, for example, that prayer is heard may work on a psychological level but (a) may not help you achieve the things you pray for, and (b) may be better explained by referring to its sedative effect than that prayers are heard.
As such, pragmatism is not antithetical to religion, but neither is it an apology for faith. However, James's metaphysical position leaves open the possibility that the ontological claims of religions are true. As he observed at the end of the Varieties, his position is not equivalent to denying the existence of transcendent realities. On the contrary, he defended the legitimate epistemic right to believe in such realities, since such beliefs do make a difference in the life of an individual and refer to statements that cannot be verified or falsified either by intellectual or common sensory reasons.
Joseph Margolis, in Historied Thought, Constructed World (California, 1995), makes a distinction between "existence" and "reality." He suggests using the term "exists" only for those things that adequately exhibit Peirce's alterity: things that offer brute physical resistance to our movements. In this way, things that affect us, such as numbers, can be said to be "real," even though they do not "exist." Margolis suggests that God, in such linguistic usage, might well be "real," causing believers to act in such and such a way, but might not "exist."
