Leonard Nelson
Leonard Nelson (; ; 11 July 1882 – 29 October 1927), sometimes spelt Leonhard, was a German mathematician, critical philosopher, and socialist. He was part of the neo-Friesian school (named after post-Kantian philosopher Jakob Friedrich Fries) of neo-Kantianism and a friend of the mathematician David Hilbert. He devised the Grelling–Nelson paradox in 1908 and the related idea of autological words with Kurt Grelling. Neo-Friesian subsequently became an influencer in fields of both philosophy and mathematics, as Nelson's close contacts with scientists and mathematicians influenced their ideas. Despite dying earlier than many of his friends and assistants, his ISK organization lived on after his death, even after being banned by the Nazi Regime in 1933. It is even claimed that Albert Einstein supported it. He's also credited with popularizing the Socratic method in his book ''Die sokratische Methode'' (''The Socratic Method'').

Berlin
Berlin ( , ) is the capital and largest city of Germany by both area and population. Its 3.7 million inhabitants make it the European Union's most populous city, according to population within city limits. One of Germany's sixteen constituent states, Berlin is surrounded by the State of Brandenburg and contiguous with Potsdam, Brandenburg's capital. Berlin's urban area, which has a population of around 4.5 million, is the second most populous urban area in Germany after the Ruhr. The Berlin-Brandenburg capital region has around 6.2 million inhabitants and is Germany's third-largest metropolitan region after the Rhine-Ruhr and Rhine-Main regions. Berlin straddles the banks of the Spree, which flows into the Havel (a tributary of the Elbe) in the western borough of Spandau. Among the city's main topographical features are the many lakes in the western and southeastern boroughs formed by the Spree, Havel and Dahme, the largest of which is Lake Müggelsee. Due to its l ...

Gustav Heckmann
Gustav Heckmann (22 April 1898 – 8 June 1996) was a German philosopher and teacher. He is particularly associated with philosophical extrapolations from the Socratic Dialogue format, pioneered by his mentor and friend Leonard Nelson, with which Heckmann continued to work after Nelson died. In 1932 he was an instigator of the so-called Urgent Call for Unity (''"Dringender Appell für die Einheit"''), a public appeal, signed by 32 high-profile intellectuals, urging the principal left wing parties to unite ahead of the first 1932 General election in order to block Nazi success. The Appeal failed in its objective, but it marked out its instigators as prominent opponents of the Nazi party: Heckmann went into exile in 1933. Twelve years later, on returning to Germany, in 1945 he became, for a few years, an influential member of the Social Democratic Party (SPD). Life Provenance and early years Gustav Heckmann was born into a traditional "church and emperor" family at ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Immanuel Kant
Immanuel Kant (, , ; 22 April 1724 – 12 February 1804) was a German philosopher and one of the central Enlightenment thinkers. Born in Königsberg, Kant's comprehensive and systematic works in epistemology, metaphysics, ethics, and aesthetics have made him one of the most influential figures in modern Western philosophy. In his doctrine of transcendental idealism, Kant argued that space and time are mere "forms of intuition" which structure all experience, and therefore that, while " things-in-themselves" exist and contribute to experience, they are nonetheless distinct from the objects of experience. From this it follows that the objects of experience are mere "appearances", and that the nature of things as they are in themselves is unknowable to us. In an attempt to counter the skepticism he found in the writings of philosopher David Hume, he wrote the '' Critique of Pure Reason'' (1781/1787), one of his most well-known works. In it, he developed his theory of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
David Hilbert
David Hilbert (; ; 23 January 1862 – 14 February 1943) was a German mathematician, one of the most influential mathematicians of the 19th and early 20th centuries. Hilbert discovered and developed a broad range of fundamental ideas in many areas, including invariant theory, the calculus of variations, commutative algebra, algebraic number theory, the foundations of geometry, spectral theory of operators and its application to integral equations, mathematical physics, and the foundations of mathematics (particularly proof theory). Hilbert adopted and defended Georg Cantor's set theory and transfinite numbers. In 1900, he presented a collection of problems that set the course for much of the mathematical research of the 20th century. Hilbert and his students contributed significantly to establishing rigor and developed important tools used in modern mathematical physics. Hilbert is known as one of the founders of proof theory and mathematical logic. Life Early life and edu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jakob Friedrich Fries
Jakob Friedrich Fries (; 23 August 1773 – 10 August 1843) was a German post-KantianTerry Pinkard, ''German Philosophy 1760-1860: The Legacy of Idealism'', Cambridge University Press, 2002, pp. 199–212. philosopher and mathematician. Biography Fries studied theology at the academy of the Moravian Brethren at Niesky and philosophy at the Universities of Leipzig and Jena. After travelling, in 1806 he became professor of philosophy and elementary mathematics at the University of Heidelberg. Though the progress of his psychological thought compelled him to abandon the positive theology of the Moravians, he retained an appreciation of its spiritual or symbolic significance. His philosophical position with regard to his contemporaries had already been made clear in his critical work ''Reinhold, Fichte und Schelling'' (1803), and in the more systematic treatises ''System der Philosophie als evidente Wissenschaft'' (1804) and ''Wissen, Glaube und Ahnung'' (1805).

Neo-Kantianism
In late modern continental philosophy, neo-Kantianism (german: Neukantianismus) was a revival of the 18th-century philosophy of Immanuel Kant. The Neo-Kantians sought to develop and clarify Kant's theories, particularly his concept of the "thing-in-itself" and his moral philosophy. It was influenced by Arthur Schopenhauer's critique of the Kantian philosophy in his work ''The World as Will and Representation'' (1818), as well as by other post-Kantian philosophers such as Jakob Friedrich Fries and Johann Friedrich Herbart. Origins The "back to Kant" movement began in the 1860s, as a reaction to the German materialist controversy in the 1850s. In addition to the work of Hermann von Helmholtz and Eduard Zeller, early fruits of the movement were Kuno Fischer's works on Kant and Friedrich Albert Lange's ''History of Materialism'' (''Geschichte des Materialismus'', 1873–75), the latter of which argued that transcendental idealism superseded the historic struggle between materia ...

Socratic Method
The Socratic method (also known as method of Elenchus, elenctic method, or Socratic debate) is a form of cooperative argumentative dialogue between individuals, based on asking and answering questions to stimulate critical thinking and to draw out ideas and underlying presuppositions. It is named after the Classical Greek philosopher Socrates and is introduced by him in Plato's Theaetetus as midwifery ( maieutics) because it is employed to bring out definitions implicit in the interlocutors' beliefs, or to help them further their understanding. The Socratic method is a method of hypothesis elimination, in that better hypotheses are found by steadily identifying and eliminating those that lead to contradictions. The Socratic method searches for general commonly held truths that shape beliefs and scrutinizes them to determine their consistency with other beliefs. The basic form is a series of questions formulated as tests of logic and fact intended to help a person or group di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grelling–Nelson Paradox
The Grelling–Nelson paradox is an antinomy, or a semantic self-referential paradox, concerning the applicability to itself of the word "heterological", meaning "inapplicable to itself". It was formulated in 1908 by Kurt Grelling and Leonard Nelson, and is sometimes mistakenly attributed to the German philosopher and mathematician Hermann Weyl. It is thus occasionally called Weyl's paradox and Grelling's paradox. It is closely related to several other well-known paradoxes, in particular, the barber paradox and Russell's paradox. The paradox Suppose one interprets the adjectives "autological" and "heterological" as follows: # An adjective is ''autological'' (sometimes ''homological'') if it describes itself. For example, the English word "English" is autological, as are "unhyphenated" and "pentasyllabic". # An adjective is ''heterological'' if it does not describe itself. Hence "long" is a heterological word (because it is not a long word), as are "hyphenated" (because it has no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Logic
Logic is the study of correct reasoning. It includes both formal and informal logic. Formal logic is the science of deductively valid inferences or of logical truths. It is a formal science investigating how conclusions follow from premises in a topic-neutral way. When used as a countable noun, the term "a logic" refers to a logical formal system that articulates a proof system. Formal logic contrasts with informal logic, which is associated with informal fallacies, critical thinking, and argumentation theory. While there is no general agreement on how formal and informal logic are to be distinguished, one prominent approach associates their difference with whether the studied arguments are expressed in formal or informal languages. Logic plays a central role in multiple fields, such as philosophy, mathematics, computer science, and linguistics. Logic studies arguments, which consist of a set of premises together with a conclusion. Premises and conclusions are usually un ...

Philosophy Of Science
Philosophy of science is a branch of philosophy concerned with the foundations, methods, and implications of science. The central questions of this study concern what qualifies as science, the reliability of scientific theories, and the ultimate purpose of science. This discipline overlaps with metaphysics, ontology, and epistemology, for example, when it explores the relationship between science and truth. Philosophy of science focuses on metaphysical, epistemic and semantic aspects of science. Ethical issues such as bioethics and scientific misconduct are often considered ethics or science studies rather than the philosophy of science. There is no consensus among philosophers about many of the central problems concerned with the philosophy of science, including whether science can reveal the truth about unobservable things and whether scientific reasoning can be justified at all. In addition to these general questions about science as a whole, philosophers of science consi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Critical Philosophy
The critical philosophy (german: kritische Philosophie) movement, attributed to Immanuel Kant (1724–1804), sees the primary task of philosophy as criticism rather than justification of knowledge. Criticism, for Kant, meant judging as to the possibilities of knowledge before advancing to knowledge itself (from the Greek ''kritike (techne)'', or "art of judgment"). The basic task of philosophers, according to this view, is not to establish and demonstrate theories about reality, but rather to subject all theories—including those about philosophy itself—to critical review, and measure their validity by how well they withstand criticism. "Critical philosophy" is also used as another name for Kant's philosophy itself. Kant said that philosophy's proper inquiry is not about what is out there in reality, but rather about the character and foundations of experience itself. We must first judge how human reason works, and within what limits, so that we can afterwards correctly apply ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
