Mental Substance
Mental substance, according to the idea held by dualists and idealists, is a non-physical substance of which minds are composed. This substance is often referred to as consciousness. This is opposed to the materialists, who hold that what we normally think of as mental substance is ultimately physical matter (i.e., brains). Descartes, who was most famous for the assertion " I think therefore I am", has had a lot of influence on the mind–body problem. He describes his theory of mental substance (which he calls ''res cogitans'' distinguishing it from the ''res extensa'') in the ''Second Meditation'' (II.8) and in ''Principia Philosophiae'' (2.002). He used a more precise definition of the word "substance" than is currently popular: that a substance is something which can exist without the existence of any other substance. For many philosophers, this word or the phrase "mental substance" has a special meaning. Gottfried Leibniz, belonging to the generation immediately after Des ...

Monad (philosophy)
The term ''monad'' () is used in some cosmic philosophy and cosmogony to refer to a most basic or original substance. As originally conceived by the Pythagoreans, the Monad is the Supreme Being, divinity or the totality of all things. In the philosophy of Gottfried Wilhelm Leibniz, there are infinite monads, which are the basic and immaterial elementary particles, or simplest units, that make up the universe. Historical background According to Hippolytus, the worldview was inspired by the Pythagoreans, who called the first thing that came into existence the "monad", which begat (bore) the dyad (from the Greek word for two), which begat the numbers, which begat the point, begetting lines or finiteness, etc. It meant divinity, the first being, or the totality of all beings, referring in cosmogony (creation theories) variously to source acting alone and/or an indivisible origin and equivalent comparators. Pythagorean and Platonic philosophers like Plotinus and Porphyry cond ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Consciousness
Consciousness, at its simplest, is sentience and awareness of internal and external existence. However, the lack of definitions has led to millennia of analyses, explanations and debates by philosophers, theologians, linguisticians, and scientists. Opinions differ about what exactly needs to be studied or even considered consciousness. In some explanations, it is synonymous with the mind, and at other times, an aspect of mind. In the past, it was one's "inner life", the world of introspection, of private thought, imagination and volition. Today, it often includes any kind of cognition, experience, feeling or perception. It may be awareness, awareness of awareness, or self-awareness either continuously changing or not. The disparate range of research, notions and speculations raises a curiosity about whether the right questions are being asked. Examples of the range of descriptions, definitions or explanations are: simple wakefulness, one's sense of selfhood or sou ...

Concepts In Metaphysics
Concepts are defined as abstract ideas. They are understood to be the fundamental building blocks of the concept behind principles, thoughts and beliefs. They play an important role in all aspects of cognition. As such, concepts are studied by several disciplines, such as linguistics, psychology, and philosophy, and these disciplines are interested in the logical and psychological structure of concepts, and how they are put together to form thoughts and sentences. The study of concepts has served as an important flagship of an emerging interdisciplinary approach called cognitive science. In contemporary philosophy, there are at least three prevailing ways to understand what a concept is: * Concepts as mental representations, where concepts are entities that exist in the mind (mental objects) * Concepts as abilities, where concepts are abilities peculiar to cognitive agents (mental states) * Concepts as Fregean senses, where concepts are abstract objects, as opposed to mental obje ...

Johannes Jacobus Poortman
Johannes Jacobus Poortman (April 26, 1896 in Rotterdam – December 21, 1970 in The Hague), studied philosophy and psychology at Groningen University under Professor Gerardus Heymans. In 1919 he received his Master of Arts; many years later he would also earn a Ph.D. He was also a theosophist. Biography Poortman studied at the universities of Hamburg, Geneva, the Sorbonne in Paris and at Vienna. From 1932 to 1938 he was member of the Council of the Dutch Society for Psychical Research. From 1958 to 1966 he was a Professor of metaphysics at the University of Leiden. After he retired his chair was successively occupied by Prof. Dubbink, Prof. van Vledder and Prof. Gerding. Poortman was the maker of the Repertory of Dutch philosophers, Repertorium der Nederlandse Wijsbegeerte, which can be consulted on line at the site of the Leiden University. He formulated the idea of a ''hylic pluralism'' (in Dutch ''hylisch pluralisme'') of the plurality of matter, a model of the universe in w ...

Pluralism (philosophy Of Mind)
Pluralism is a term used in philosophy, meaning "doctrine of multiplicity," often used in opposition to monism ("doctrine of unity") and dualism ("doctrine of duality"). The term has different meanings in metaphysics, ontology, epistemology and logic. In metaphysics, pluralism is the doctrine that contradicts the assertions of monism and dualism, and claims that there are in fact many different substances in nature that constitute reality. In ontology, pluralism refers to different ways, kinds, or modes of being. For example, a topic in ontological pluralism is the comparison of the modes of existence of things like 'humans' and 'cars' with things like 'numbers' and some other concepts as they are used in science. In epistemology, pluralism is the position that there is not one consistent means of approaching truths about the world, but rather many. Often this is associated with pragmatism, or conceptual, contextual, or cultural relativism. In the philosophy of science it may re ...

Monism
Monism attributes oneness or singleness (Greek: μόνος) to a concept e.g., existence. Various kinds of monism can be distinguished: * Priority monism states that all existing things go back to a source that is distinct from them; e.g., in Neoplatonism everything is derived from The One. In this view only the One is ontologically basic or prior to everything else. * Existence monism posits that, strictly speaking, there exists only a single thing, the universe, which can only be artificially and arbitrarily divided into many things. * Substance monism asserts that a variety of existing things can be explained in terms of a single reality or substance. Substance monism posits that only one kind of substance exists, although many things may be made up of this substance, e.g., matter or mind. * Dual-aspect monism is the view that the mental and the physical are two aspects of, or perspectives on, the same substance. * Neutral monism believes the fundamental nature of reality ...

Dualism (philosophy Of Mind)
Dualism most commonly refers to: * Mind–body dualism, a philosophical view which holds that mental phenomena are, at least in certain respects, not physical phenomena, or that the mind and the body are distinct and separable from one another ** Property dualism, a view in the philosophy of mind and metaphysics which holds that, although the world is composed of just one kind of substance—the physical kind—there exist two distinct kinds of properties: physical properties and mental properties * Cosmological dualism, the theological or spiritual view that there are only two fundamental concepts, such as "good" and "evil", and that these two concepts are in every way opposed to one another Dualism may also refer to: * Dualism (cybernetics), systems or problems in which an intelligent adversary attempts to exploit the weaknesses of the investigator * Dualism (Indian philosophy), the belief held by certain schools of Indian philosophy that reality is fundamentally composed of two ...

Monadology
The ''Monadology'' (french: La Monadologie, 1714) is one of Gottfried Leibniz's best known works of his later philosophy. It is a short text which presents, in some 90 paragraphs, a metaphysics of simple substances, or '' monads''. Text During his last stay in Vienna from 1712 to September 1714, Leibniz wrote two short texts in French which were meant as concise expositions of his philosophy. After his death, ''Principes de la nature et de la grâce fondés en raison'', which was intended for prince Eugene of Savoy, appeared in French in the Netherlands. Christian Wolff and collaborators published translations in German and Latin of the second text which came to be known as ''The Monadology''. Without having seen the Dutch publication of the ''Principes'' they had assumed that it was the French original of the ''Monadology,'' which in fact remained unpublished until 1840. The German translation appeared in 1720 as ''Lehrsätze über die Monadologie'' and the following year ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gottfried Leibniz
Gottfried Wilhelm (von) Leibniz . ( – 14 November 1716) was a German polymath active as a mathematician, philosopher, scientist and diplomat. He is one of the most prominent figures in both the history of philosophy and the history of mathematics. He wrote works on philosophy, theology, ethics, politics, law, history and philology. Leibniz also made major contributions to physics and technology, and anticipated notions that surfaced much later in probability theory, biology, medicine, geology, psychology, linguistics and computer science. In addition, he contributed to the field of library science: while serving as overseer of the Wolfenbüttel library in Germany, he devised a cataloging system that would have served as a guide for many of Europe's largest libraries. Leibniz's contributions to this vast array of subjects were scattered in various learned journals, in tens of thousands of letters and in unpublished manuscripts. He wrote in several languages, primarily in Latin, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Idealism
In philosophy, the term idealism identifies and describes metaphysical perspectives which assert that reality is indistinguishable and inseparable from perception and understanding; that reality is a mental construct closely connected to ideas. Idealist perspectives are in two categories: subjective idealism, which proposes that a material object exists only to the extent that a human being perceives the object; and objective idealism, which proposes the existence of an ''objective'' consciousness that exists prior to and independently of human consciousness, thus the existence of the object is independent of human perception. The philosopher George Berkeley said that the essence of an object is to be perceived. By contrast, Immanuel Kant said that idealism "does not concern the existence of things", but that "our modes of representation" of things such as ''space'' and ''time'' are not "determinations that belong to things in themselves", but are essential features of the ...

Principia Philosophiae
''Principles of Philosophy'' ( la, Principia Philosophiae) is a book by René Descartes. In essence, it is a synthesis of the ''Discourse on Method'' and ''Meditations on First Philosophy''.Guy Durandin, ''Les Principes de la Philosophie. Introduction et notes'', Librairie Philosophique J. Vrin, Paris, 1970. It was written in Latin, published in 1644 and dedicated to Elisabeth of Bohemia, with whom Descartes had a long-standing friendship. A French version (''Les Principes de la Philosophie'') followed in 1647. The book sets forth the principles of nature—the Laws of Physics—as Descartes viewed them. Most notably, it set forth the principle that in the absence of external forces, an object's motion will be uniform and in a straight line. Newton borrowed this principle from Descartes and included it in his own '' Principia''; to this day, it is still generally referred to as Newton's First Law of Motion. The book was primarily intended to replace the Aristotelian curriculum ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
