Category="Idealism"Category="Metaphysics"Category="Philosophy of mind"This article is about the philosophical notion of Idealism. Idealism is also a term in international relations theory and in Christian eschatology.Idealism is an approach to philosophical enquiry. The ideal, in these systems, relates to direct knowledge of subjective mental ideas, or images. It is usually juxtaposed with Realism in which the real is said to have absolute existence prior to and independent of our knowledge. Ontological idealists might insist that the only things that really exist are ideas. Epistemological idealists might insist that the only things which can be directly known for certain are ideas.
History
Idealism names a number of philosophical positions with quite different tendencies and implications. Plato
Plato proposed an idealist theory as a solution to the Problem of universals. A universal is that which all things share in virtue of having some particular property. So for example the wall, the moon and a blank sheet of paper are all white; white is the universal that all white things share. Plato argued that it is universals, The Forms, or Platonic Ideals that are real, not specific individual things. Confusingly, because this idea asserts that these mental entities are real, it is also called Platonic realism; in this sense realism contrasts with Nominalism, the notion that mental abstractions are merely names without an independent existence. Nevertheless, it is a form of idealism because it asserts the primacy of the idea of universals over material things. Plotinus
Schopenhauer wrote of this Neoplatonist philosopher: "With Plotinus there even appears, probably for the first time in Western philosophy, idealism that had long been current in the East even at that time, for it taught (Enneads, iii, lib. vii, c.10) that the Soul has made the world by stepping from Eternity into time, with the explanation: 'For there is for this Universe no other place than the soul or Mind' (neque est alter hujus universi locus quam anima), indeed the ideality of time is expressed in the words: 'We should not accept time outside the soul or mind' (oportet autem nequaquam extra animam tempus accipere)." (Parerga and Paralipomena, Volume I, "Fragments for the History of Philosophy," § 7)Malebranche
If the only things that we know for certain are the ideas within our mind, then the existence of the external world would be dubious and known only indirectly. Malebranche, however, disagreed. He declared that the real external world is actually God. All activity only appears to occur in the external world. In actuality, it is the activity of God. For Malebranche, we directly know internally the ideas in our mind. Externally, we directly know God's operations. This kind of idealism led to the pantheism of Spinoza.George Berkeley
Bishop Berkeley, in seeking to find out what we could know with certainty, decided that our knowledge must be based on our perceptions. This led him to conclude that there was indeed no "real" knowable object behind one's perception, that what was "real" was the perception itself. This Subjective idealism or dogmatic idealism led to his placing the full weight of justification on our perceptions. This left Berkeley with the problem, common to other forms of idealism, of explaining how it is that each of us apparently has much the same sort of perceptions of an object. He solved this problem by having God intercede, as the immediate cause of all of our perceptions. Schopenhauer wrote: "Berkeley was, therefore, the first to treat the subjective starting-point really seriously and to demonstrate irrefutably its absolute necessity. He is the father of idealism...." (Parerga and Paralipomena, Vol. I, "Fragments for the History of Philosophy," § 12)Arthur Collier
Arthur Collier published the same assertions that were made by Berkeley. However, there seemed to have been no influence between the two contemporary writers. Collier claimed that the represented image of an external object is the only knowable reality. Matter, as a cause of the representative image, is unthinkable and therefore nothing to us. An external world, as absolute matter, unrelated to an observer, does not exist for human perceivers. As an appearance in a mind, the universe cannot exist if there is no perceiving mind.Collier was influenced by John Norris's An Essay Towards the Theory of the Ideal or Intelligible World 1701. The idealist statements by Collier were generally dismissed by readers who were not able to reflect on the distinction between a mental idea or image and the object that it represents.
Edwards, an American theologian, went to Yale University in 1716 at the age of thirteen. After reading Locke's doctrine of ideas, he kept a notebook entitled "Mind." In it, he wrote, at the age of fourteen, that the only things that are real are minds. He contended that Matter exists only as an IDEA in a mind. Due to his theological manner of thinking, he asserted that space is God, due to its infinity. After adolescence, he never elaborated on these early idealistic notes.Immanuel Kant
Immanuel Kant held that the mind forces the world we perceive to take the shape of space-and-time. Kant focused on the idea drawn from British Empiricism, and its philosophers such as Locke, Berkeley, and Hume, that all we can know is the mental impressions, or phenomena, that an outside world which may or may not exist independently creates in our minds; our minds can never perceive that outside world directly. Kant's postscript to this added that the mind is not a "blank slate", but comes equipped with categories for organising our sense impressions. This Kantian sort of idealism opens up a world of abstractions to be explored by reason, but in sharp contrast to Plato's, leaves only uncertainties about a knowable world outside our own minds. We cannot approach the Noumenon, the "Thing in Itself" (German: Ding an Sich) outside our own mental world. This sort of idealism goes by the equally counterintuitive name of Transcendental idealism.Hegel
Hegel, another philosopher whose system has been called idealism, thought that history must be rational in something significantly like the way science is. His famous dictum is that "the Real is Rational"; Reason is the arbiter that shapes the world as it is, and gives us access to what is real. Hegel's idealism posits that since ideas about reality are products of the Mind, there must be a mind at work in the universe that establishes reality and gives it structure. Hegelian idealism goes by the name of Absolute idealism. Schopenhauer
In the first volume of his Parerga and Paralipomena, Schopenhauer wrote his Sketch of a History of the Doctrine of the Ideal and the Real. He defined the ideal as being mental pictures that constitute subjective Knowledge. The ideal, for him, is what can be attributed to our own minds. The images in our head are what comprise the ideal. Schopenhauer emphasized that we are restricted to our own Consciousness. The world that appears there is only a representation or mental picture of an object. We directly and immediately know only these representations. All objects that are external to the mind are known indirectly through the mediation of our Mind.Schopenhauer's history is an account of the Concept of the "ideal" in its meaning as "ideas in a subject's mind." In this sense, "ideal" means "ideational." He does not refer to the other meaning of "ideal" as being qualities of the highest perfection and excellence.
British idealism
British idealism enjoyed ascendancy in English-speaking philosophy in the later part of the 19th century. F. H. Bradley of Merton College, Oxford, saw reality as a monistic whole, which is apprehended through "feeling", a state in which there is no distinction between the perception and the thing perceived. Bradley was the apparent target of G. E. Moore's radical rejection of idealism.J. M. E. McTaggart of Cambridge University, argued that minds alone exist, and that they only relate to each other through love. Space, time and material objects are for McTaggart unreal. He argued, for instance, in The Unreality of Time that it was not possible to produce a coherent account of a sequence of events in time, and that therefore time is an illusion.
Karl Pearson
In The Grammar of Science, Preface to the 2nd Edition, 1900, Karl Pearson wrote, "There are many signs that a sound idealism is surely replacing, as a basis for natural philosophy, the crude Materialism of the older physicists." This book influenced Einstein's regard for the importance of the observer in scientific measurements. In § 5 of that book, Pearson asserted that "...science is in reality a classification and analysis of the contents of the Mind...." Also, "...the field of science is much more Consciousness than an external world."Critique of Idealism
G. E. Moore
The most influential criticism of Idealism is Moore's The Refutation of Idealism. This was the first application of Moore's analytic philosophical method, which greatly influenced Analytic philosophy.Moore proceeds by examining the Berkeleian aphorism esse is percipi: "to be is to be perceived". He examines in detail each of the three terms in the aphorism, finding that it must mean that the object and the subject are necessarily connected. So, he argues, for the idealist, "yellow" and "the sensation of yellow" are necessarily identical - to be yellow is necessarily to be experienced as yellow. But, in a move similar to the open question argument, it also seems clear that there is a difference between "yellow" and "the sensation of yellow". For Moore, the idealist is in error because "that esse is held to be percipi, solely because what is experienced is held to be identical with the experience of it".
David Stove
The Australian philosopher David Stove argued in typically acerbic style that idealism rested on what he called "the worst argument in the world". He named one version of this argument, deriving from Berkeley, "the Gem". Berkeley claimed that "(the mind) is deluded to think it can and does conceive of bodies existing unthought of, or without the mind, though at the same time they are apprehended by, or exist in, itself". Stove argued that this claim proceeds from the tautology that nothing can be thought of without its being thought of, to the conclusion that nothing can exist without its being thought of. Presented in this way, the argument is not even a syllogism - hardly an argument at all.John Searle
In The Construction of Social Reality John Searle offers an attack on some versions of idealism. Searle conveniently summarises two important arguments for idealism. The first is based on our perception of reality:- 1. All we have access to in perception are the contents of our own experiences
- 2. The only epistemic basis we can have for claims about the external world are our perceptual experiences
therefore,
- 3. the only reality we can meaningfully speak of is the reality of perceptual experiences (The Construction of Social Reality p. 172)
Whilst agreeing with (2), Searle argues that (1) is false, and points out that (3) does not follow from (1) and (2).
The second argument for idealism runs as follows:
- Premise: Any cognitive state occurs as part of a set of cognitive states and within a cognitive system
- Conclusion 1: It is impossible to get outside of all cognitive states and systems to survey the relationships between them and the reality they are used to cognize
- Conclusion 2: No cognition is ever of a reality that exists independently of cognition (The Construction of Social Reality p. 174)
Searle goes on to point out that conclusion 2 simply does not follow from its precedents.
Idealism in religious thought
Not all Religion and belief in the Supernatural is, strictly speaking, anti-materialist in nature. While many types of religious belief are indeed specifically idealist, for example, Hindu beliefs about the nature of the Brahman, Zen Buddhism stands in the middle way of dialectics between idealism and materialism, and mainstream Christian doctrine affirms the importance of the materiality of Christ's human body and the necessity of self-restraint when dealing with the material world.Several modern religious movements and texts, for example the organisations within the New Thought Movement (especially the Unity Church) and the book, A Course In Miracles, may be said to have a particularly idealist orientation. The Theology of Christian Science is explicitly idealist.
More accurately, Idealism is based on the root word "Ideal," meaning a perfect form of, and is most accurately described as a belief in perfect forms of virtue, truth, and the absolute. Idea-ism may be a more appropriate term for the definitions listed above. There is a clear distinction between an idea and an ideal (i.e. Websters Dictionary says "conforming exactly to an ideal, law, or standard: perfect.").
Other uses
In general parlance, "idealism" or "idealist" is also used to describe a person having high ideals, sometimes with the connotation that those ideals are unrealisable or at odds with "practical" life.The word "ideal" is commonly used as an adjective to designate qualities of perfection, desirability, and excellence. This is foreign to the epistemological use of the word "idealism" which pertains to internal mental Representations. These internal ideas represent objects that are assumed to exist outside of the mind.
