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. Nelson subsequently became influential in both philosophy and mathematics, as his 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'').

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 Voerd ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Post-Kantian
German idealism is a philosophical movement that emerged in Germany in the late 18th and early 19th centuries. It developed out of the work of Immanuel Kant in the 1780s and 1790s, and was closely linked both with Romanticism and the revolutionary politics of the Enlightenment. The period of German idealism after Kant is also known as post-Kantian idealism or simply post-Kantianism. One scheme divides German idealists into transcendental idealists, associated with Kant and Fichte, and absolute idealists, associated with Schelling and Hegel. Meaning of idealism As a philosophical position, idealism claims that the true objects of knowledge are "ideal," meaning mind-dependent, as opposed to material. The term stems from Plato's view that the " Ideas," the categories or concepts which our mind abstracts from our empirical experience of particular things, are more real than the particulars themselves, which depend on the Ideas rather than the Ideas depending on them. In the contex ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neo-Friesian School
In late modern philosophy, neo-Kantianism () 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 ethics, moral philosophy. Origins The "back to Kant" movement began in the 1860s, as a reaction to the German materialism, 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 material idealism and Mechanism (philosophy), mechanistic materialism. Fischer was earlier involved in a dispute with the Aristotelianism, Aristotelian German idealism, idealist Friedrich Adolf Trendelenburg concerning the interpretation of the results of the Trans ...

Socialist
Socialism is an economic ideology, economic and political philosophy encompassing diverse Economic system, economic and social systems characterised by social ownership of the means of production, as opposed to private ownership. It describes the Economic ideology, economic, Political philosophy, political, and Social theory, social theories and Political movement, movements associated with the implementation of such systems. Social ownership can take various forms, including State ownership, public, Community ownership, community, Collective ownership, collective, cooperative, or Employee stock ownership, employee.: "Just as private ownership defines capitalism, social ownership defines socialism. The essential characteristic of socialism in theory is that it destroys social hierarchies, and therefore leads to a politically and economically egalitarian society. Two closely related consequences follow. First, every individual is entitled to an equal ownership share that earns an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mathematician
A mathematician is someone who uses an extensive knowledge of mathematics in their work, typically to solve mathematical problems. Mathematicians are concerned with numbers, data, quantity, mathematical structure, structure, space, Mathematical model, models, and mathematics#Calculus and analysis, change. History One of the earliest known mathematicians was Thales of Miletus (); he has been hailed as the first true mathematician and the first known individual to whom a mathematical discovery has been attributed. He is credited with the first use of deductive reasoning applied to geometry, by deriving four corollaries to Thales's theorem. The number of known mathematicians grew when Pythagoras of Samos () established the Pythagorean school, whose doctrine it was that mathematics ruled the universe and whose motto was "All is number". It was the Pythagoreans who coined the term "mathematics", and with whom the study of mathematics for its own sake begins. The first woman math ...

Socratic Method
The Socratic method (also known as the method of Elenchus or Socratic debate) is a form of argumentative dialogue between individuals based on asking and answering questions. Socratic dialogues feature in many of the works of the ancient Greek philosopher Plato, where his teacher Socrates debates various philosophical issues with an "interlocutor" or "partner". In Plato's dialogue "Theaetetus (dialogue), Theaetetus", Socrates describes his method as a form of "midwifery" because it is employed to help his interlocutors develop their understanding in a way analogous to a Prenatal development, child developing in the womb. The Socratic method begins with commonly held beliefs and scrutinizes them by way of questioning to determine their internal consistency and their coherence with other beliefs and so to bring everyone closer to the truth. In modified forms, it is employed today in a variety of pedagogy, pedagogical contexts. Development In the second half of the 5th century B ...

Grelling–Nelson Paradox
The Grelling–Nelson paradox arises from the question of whether the term "non-self-descriptive" is self-descriptive. It was formulated in 1908 by Kurt Grelling and Leonard Nelson, and is sometimes mistakenly attributed to the German philosopher and mathematician Hermann Weyl thus occasionally called Weyl's paradox or Grelling's paradox. It is closely related to several other well-known paradoxes, in particular, the barber paradox and Russell's paradox. It is an antinomy, or a semantic self-referential paradox. 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 hyphen) and "monosy ...

Logic
Logic is the study of correct reasoning. It includes both formal and informal logic. Formal logic is the study of deductively valid inferences or logical truths. It examines how conclusions follow from premises based on the structure of arguments alone, independent of their topic and content. Informal logic is associated with informal fallacies, critical thinking, and argumentation theory. Informal logic examines arguments expressed in natural language whereas formal logic uses formal language. When used as a countable noun, the term "a logic" refers to a specific logical formal system that articulates a proof system. Logic plays a central role in many fields, such as philosophy, mathematics, computer science, and linguistics. Logic studies arguments, which consist of a set of premises that leads to a conclusion. An example is the argument from the premises "it's Sunday" and "if it's Sunday then I don't have to work" leading to the conclusion "I don't have to wor ...

Philosophy Of Science
Philosophy of science is the branch of philosophy concerned with the foundations, methods, and implications of science. Amongst its central questions are the difference between science and non-science, the reliability of scientific theories, and the ultimate purpose and meaning of science as a human endeavour. Philosophy of science focuses on metaphysical, epistemic and semantic aspects of scientific practice, and overlaps with metaphysics, ontology, logic, and epistemology, for example, when it explores the relationship between science and the concept of truth. Philosophy of science is both a theoretical and empirical discipline, relying on philosophical theorising as well as meta-studies of scientific practice. Ethical issues such as bioethics and scientific misconduct are often considered ethics or science studies rather than the philosophy of science. Many of the central problems concerned with the philosophy of science lack contemporary consensus, including whether ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Critical Philosophy
Critical philosophy () is a movement inaugurated by Immanuel Kant (1724–1804). It is dedicated to the self-examination of reason with the aim of exposing its inherent limitations, that is, to defining the possibilities of knowledge as a prerequisite to advancing to knowledge itself. According to Kant, only after such self-criticism does it become possible to develop metaphysics in a non-dogmatic way. The three critical texts of the Kantian corpus are the ''Critique of Pure Reason'', '' Critique of Practical Reason'' and ''Critique of Judgement'', published between 1781 and 1790 and primarily concerned, respectively, with metaphysics, morality, and teleology. Contemporaries of Kant such as Johann Georg Hamann and Johann Gottfried Herder rejected the notion of "pure" reason upon which this project depends. They claim that reason depends upon language, which always introduces historical contingencies. See also * Critical idealism *Critical thinking * Charles Bernard Renouv ...
