Inverted Spectrum
The inverted spectrum is the hypothetical concept, pertaining to the philosophy of color, of two people sharing their color vocabulary and discriminations, although the colors one sees—one's qualia—are systematically different from the colors the other person sees. Overview The concept dates back to John Locke. It invites us to imagine that we wake up one morning, and find that for some unknown reason all the colors in the world have been inverted, i.e. swapped to the hue on the opposite side of a color wheel, the complementary color. Furthermore, we discover that no physical changes have occurred in our brains or bodies that would explain this phenomenon. Supporters of the hypothesis of qualia as non-physical entities argue that, since we can imagine this happening without contradiction, it follows that we are imagining a change in a property that determines the way things look to us, but that has no physical basis.

Hypothesis
A hypothesis (plural hypotheses) is a proposed explanation for a phenomenon. For a hypothesis to be a scientific hypothesis, the scientific method requires that one can test it. Scientists generally base scientific hypotheses on previous observations that cannot satisfactorily be explained with the available scientific theories. Even though the words "hypothesis" and "theory" are often used interchangeably, a scientific hypothesis is not the same as a scientific theory. A working hypothesis is a provisionally accepted hypothesis proposed for further research in a process beginning with an educated guess or thought. A different meaning of the term ''hypothesis'' is used in formal logic, to denote the antecedent of a proposition; thus in the proposition "If ''P'', then ''Q''", ''P'' denotes the hypothesis (or antecedent); ''Q'' can be called a consequent. ''P'' is the assumption in a (possibly counterfactual) ''What If'' question. The adjective ''hypothetical'', meaning "hav ...

Skepticism
Skepticism, also spelled scepticism, is a questioning attitude or doubt toward knowledge claims that are seen as mere belief or dogma. For example, if a person is skeptical about claims made by their government about an ongoing war then the person doubts that these claims are accurate. In such cases, skeptics normally recommend not disbelief but suspension of belief, i.e. maintaining a neutral attitude that neither affirms nor denies the claim. This attitude is often motivated by the impression that the available evidence is insufficient to support the claim. Formally, skepticism is a topic of interest in philosophy, particularly epistemology. More informally, skepticism as an expression of questioning or doubt can be applied to any topic, such as politics, religion, or pseudoscience. It is often applied within restricted domains, such as morality ( moral skepticism), atheism (skepticism about the existence of God), or the supernatural. Some theorists distinguish "good" or moder ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ontological Argument
An ontological argument is a philosophical argument, made from an ontological basis, that is advanced in support of the existence of God. Such arguments tend to refer to the state of being or existing. More specifically, ontological arguments are commonly conceived ''a priori'' in regard to the organization of the universe, whereby, if such organizational structure is true, God must exist.

"There are three main periods in the history of ontological arguments. The first was in 11th century, when St. Anselm of Canterbury came up with the first ontological argument" (p. 22). was proposed by Saint Anselm of Canterbury in his 1078 work, ''Proslogion'' (), in which he defines God as "a being than which no greater can be conceived," and argues that such being must exist in the mind, even in that of the person who denies the existence of God.

Mary's Room
The knowledge argument (also known as Mary's room or Mary the super-scientist) is a philosophical thought experiment proposed by Frank Jackson in his article "Epiphenomenal Qualia" (1982) and extended in "What Mary Didn't Know" (1986). The experiment describes Mary, a scientist who exists in a black and white world where she has extensive access to physical descriptions of color, but no actual human perceptual experience of color. The central question of the thought experiment is whether Mary will gain new knowledge when she goes outside the black and white world and experiences seeing in color. The experiment is intended to argue against physicalism—the view that the universe, including all that is mental, is entirely physical. The debate that emerged following its publication became the subject of an edited volume—''There's Something About Mary'' (2004)—which includes replies from such philosophers as Daniel Dennett, David Lewis, and Paul Churchland. Thought experiment Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Further Facts
In philosophy, further facts are facts that do not follow logically from the physical facts of the world. Reductionists who argue that at bottom there is nothing more than the physical facts thus argue against the existence of further facts. The concept of further facts plays a key role in some of the major works in analytic philosophy of the late 20th century, including in Derek Parfit's ''Reasons and Persons'', and David Chalmers's ''The Conscious Mind''. One context in which the existence of further facts is debated is that of personal identity across time: in what sense is Alice today really the ''same'' person as Alice yesterday, given that across the two days the state of her brain is different and the atoms that constitute her are different? One may believe that at bottom, there is nothing more than the atoms and their arrangement at different points in time; while we may for practical purposes come up with some notion of sameness of a person, this notion does not reflec ...

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 ...

Musical Note
In music, a note is the representation of a musical sound. Notes can represent the Pitch (music), pitch and Duration (music), duration of a sound in musical notation. A note can also represent a pitch class. Notes are the building blocks of much written music: musical analysis#Discretization, discretizations of musical phenomena that facilitate performance, comprehension, and musical analysis, analysis. The term ''note'' can be used in both generic and specific senses: one might say either "the piece 'Happy Birthday to You' begins with two notes having the same pitch", or "the piece begins with two repetitions of the same note". In the former case, one uses ''note'' to refer to a specific musical event; in the latter, one uses the term to refer to a class of events sharing the same pitch. (See also: Key signature names and translations.) Two notes with fundamental frequency, fundamental frequencies in a ratio equal to any integer power of two (e.g., half, twice, or four times ...

Voice Inversion
Voice inversion scrambling is an analog method of obscuring the content of a transmission. It is sometimes used in public service radio, automobile racing, cordless telephones and the Family Radio Service. Without a descrambler, the transmission makes the speaker "sound like Donald Duck". It is called "voice inversion", but the technique operates on the passband of the information and so can be applied to any information being transmitted. Forms and details There are various forms of voice inversion which offer differing levels of security. Overall, voice inversion scrambling offers little true security as software and even hobbyist kits are available from kit makers for scrambling and descrambling. The cadence of the speech is not changed. It is often easy to guess what is happening in the conversation by listening for other audio cues like questions, short responses and other language cadences. In the simplest form of voice inversion, the frequency p of each component is replaced ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Imprisonment
Imprisonment is the restraint of a person's liberty, for any cause whatsoever, whether by authority of the government, or by a person acting without such authority. In the latter case it is "false imprisonment". Imprisonment does not necessarily imply a place of confinement, with bolts and bars, but may be exercised by any use or display of force (such as placing one in handcuffs), lawfully or unlawfully, wherever displayed, even in the open street. People become prisoners, wherever they may be, by the mere word or touch of a duly authorized officer directed to that end. Usually, however, imprisonment is understood to imply an actual confinement in a jail or prison employed for the purpose according to the provisions of the law. Sometimes incarceration of women, gender imbalances occur in imprisonment rates, with incarceration of males proportionately more likely than incarceration of females.

Liberty
Liberty is the ability to do as one pleases, or a right or immunity enjoyed by prescription or by grant (i.e. privilege). It is a synonym for the word freedom. In modern politics, liberty is understood as the state of being free within society from control or oppressive restrictions imposed by authority on one's way of life, behavior, or political views. In theology, liberty is freedom from the effects of "sin, spiritual servitude, rworldly ties". Sometimes liberty is differentiated from freedom by using the word "freedom" primarily, if not exclusively, to mean the ability to do as one wills and what one has the power to do; and using the word "liberty" to mean the absence of arbitrary restraints, taking into account the rights of all involved. In this sense, the exercise of liberty is subject to capability and limited by the rights of others. Thus liberty entails the responsible use of freedom under the rule of law without depriving anyone else of their freedom. Liberty can be ...

Political Spectrum
A political spectrum is a system to characterize and classify different political positions in relation to one another. These positions sit upon one or more geometric axes that represent independent political dimensions. The expressions political compass and political map are used to refer to the political spectrum as well, especially to popular two-dimensional models of it. Most long-standing spectra include the left–right dimension as a measure of social, political and economic hierarchy which originally referred to seating arrangements in the French parliament after the Revolution (1789–1799), with radicals on the left and aristocrats on the right. While communism and socialism are usually regarded internationally as being on the left, conservatism and reactionism are generally regarded as being on the right. Liberalism can mean different things in different contexts, being sometimes on the left (social liberalism) and other times on the right (conservative liberalis ...

Solipsism
Solipsism (; ) is the philosophical idea that only one's mind is sure to exist. As an epistemological position, solipsism holds that knowledge of anything outside one's own mind is unsure; the external world and other minds cannot be known and might not exist outside the mind. Varieties There are varying degrees of solipsism that parallel the varying degrees of skepticism: Metaphysical Metaphysical solipsism is a variety of solipsism. Based on a philosophy of subjective idealism, metaphysical solipsists maintain that the self is the only existing reality and that all other realities, including the external world and other persons, are representations of that self, and have no independent existence. There are several versions of metaphysical solipsism, such as Caspar Hare's egocentric presentism (or perspectival realism), in which other people are conscious, but their experiences are simply not ''present''. Epistemological Epistemological solipsism is the variety of ideali ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
