William James in the context of "Bernard Bosanquet (philosopher)"

Verificationism, also known as the verification principle or the verifiability criterion of meaning, is a doctrine in philosophy and the philosophy of language which holds that a declarative sentence is cognitively meaningful only if it is either analytic or tautological (true or false in virtue of its logical form and definitions) or at least in principle verifiable by experience. On this view, many traditional statements of metaphysics, theology, and some of ethics and aesthetics are said to lack truth value or factual content, even though they may still function as expressions of emotions or attitudes rather than as genuine assertions. Verificationism was typically formulated as an empiricist criterion of cognitive significance: a proposed test for distinguishing meaningful, truth-apt sentences from "nonsense".

As a self-conscious movement, verificationism was a central thesis of logical positivism (or logical empiricism), developed in the 1920s and 1930s by members of the Vienna Circle and their allies in early analytic philosophy. Drawing on earlier empiricism and positivism (especially David Hume, Auguste Comte and Ernst Mach), on pragmatism (notably C. S. Peirce and William James), and on the logical and semantic innovations of Gottlob Frege and the early Wittgenstein, these philosophers sought a "scientific" conception of philosophy in which meaningful discourse would either consist in empirical claims ultimately testable by observation or in analytic truths of logic and mathematics. The verification principle was intended to explain why many traditional metaphysical disputes seemed irresolvable, to demarcate science from pseudo-science and speculative metaphysics, and to vindicate the special status of the natural sciences by taking empirical testability as the paradigm of serious inquiry.

The specious present is defined as the "supposed time between past and future" or "a present that lasts a short stretch of physical time". The term was coined by E. R. Clay in his 1882 book The Alternative: A Study in Psychology, and cited by William James in The Principles of Psychology. It can be classed as a "thick" conception of time perception, to be contrasted with "thin" conceptions that see the present as instantaneous.

A mystical or religious experience, also known as a spiritual experience or sacred experience, is a subjective experience which is interpreted within a religious framework. In a strict sense, "mystical experience" refers specifically to an ecstatic unitive experience, or nonduality, of 'self' and other objects, but more broadly may also refer to non-sensual or unconceptualized sensory awareness or insight, while religious experience may refer to any experience relevant in a religious context. Mysticism entails religious traditions of human transformation aided by various practices and religious experiences.

The concept of mystical or religious experience developed in the 19th century, as a defense against the growing rationalism of western society. William James popularized the notion of distinct religious or mystical experiences in his Varieties of Religious Experience, and influenced the understanding of mysticism as a distinctive experience which supplies knowledge of the transcendental.

Self-reflection is the ability to witness and evaluate one's own cognitive, emotional, and behavioural processes. In psychology, other terms used for this self-observation include "reflective awareness" and "reflective consciousness", which originate from the work of William James.

Self-reflection depends upon a range of functions, including introspection and metacognition, which develop from infancy through adolescence, affecting how individuals interact with others, and make decisions.

The metaphor "stream of consciousness" suggests how thoughts seem to flow through the conscious mind. Research studies have shown that humans only experience one mental event at a time, as a fast-moving mind-stream. The full range of thoughts one can be aware of forms the content of this "stream".

The term was coined by Alexander Bain in 1855, when he wrote in The Senses and the Intellect, "The concurrence of Sensations in one common stream of consciousness (on the same cerebral highway) enables those of different senses to be associated as readily as the sensations of the same sense". But the man who popularized it is commonly credited instead: William James, often considered the father of American psychology, used it in 1890 in The Principles of Psychology.

Pragmatism is a philosophical tradition that views language and thought as tools for prediction, problem solving, and action, rather than describing, representing, or mirroring reality. Pragmatists contend that most philosophical topics—such as the nature of knowledge, language, concepts, meaning, belief, and science—are best viewed in terms of their practical uses and successes.

Pragmatism began in the United States in the 1870s. Its origins are often attributed to philosophers Charles Sanders Peirce, William James and John Dewey. In 1878, Peirce described it in his pragmatic maxim: "Consider the practical effects of the objects of your conception. Then, your conception of those effects is the whole of your conception of the object."

Empirical psychology (German: empirische Psychologie) is the work of a number of nineteenth century German-speaking pioneers of experimental psychology, including William James, Wilhelm Wundt and others. It also includes several philosophical theories of psychology which based themselves on the epistemological standpoint of empiricism, e.g., Franz Brentano's Psychology from an Empirical Standpoint (1874).

American philosophy is the activity, corpus, and tradition of philosophers affiliated with the United States. The Internet Encyclopedia of Philosophy notes that while it lacks a "core of defining features, American Philosophy can nevertheless be seen as both reflecting and shaping collective American identity over the history of the nation". The philosophy of the Founding Fathers of the United States is largely seen as an extension of the European Enlightenment. A small number of philosophies are known as American in origin, namely pragmatism and transcendentalism, with their most prominent proponents being the philosophers William James and Ralph Waldo Emerson respectively.

Georges Eugène Sorel (/səˈrɛl/; French: [ʒɔʁʒ øʒɛn sɔʁɛl]; 2 November 1847 – 29 August 1922) was a French social thinker, political theorist, historian, and later journalist. He has inspired theories and movements grouped under the name of Sorelianism. His social and political philosophy owed much to his reading of Proudhon, Karl Marx, Giambattista Vico, Henri Bergson (whose lectures at the Collège de France he attended), and later William James. His notion of the power of myth in collective agency inspired socialists, anarchists, Marxists, and fascists. Together with his defense of violence, the power of myth is the contribution for which he is most often remembered.

Politically he evolved from his early liberal-conservative positions towards Marxism, social-democracy, and eventually syndicalism. Between 1909 and 1910 he was marginally involved with Charles Maurras' Action Française, and between 1911 and 1913 he wrote for the politically transversal L'Indépendance, established together with Édouard Berth – one of Sorel's main disciples – and Georges Valois, closer to Maurrassian circles. After a long silence during the war, Sorel came out in favour of Lenin and moved towards Bolshevist positions until his death in 1922.

Suggestion is the psychological process by which a person guides their own or another person's desired thoughts, feelings, and behaviors by presenting stimuli that may elicit them as reflexes instead of relying on conscious effort.

Nineteenth-century writers on psychology such as William James used the words "suggest" and "suggestion" in the context of a particular idea which was said to suggest another when it brought that other idea to mind. Early scientific studies of hypnosis by Clark Leonard Hull and others extended the meaning of these words in a special and technical sense (Hull, 1933).
