Here Is One Hand
Here is one hand is an epistemological argument created by G. E. Moore in reaction against philosophical skepticism and in support of common sense. The argument takes the following form: * Here is one hand, * And here is another. * There are at least two external objects in the world. * Therefore, an external world exists. Introduction G. E. Moore wrote " A Defence of Common Sense" and ''Proof of an External World''. For the purposes of these essays, he posed skeptical hypotheses, such as " you may be dreaming" or " the world is 5 minutes old", and then provided his own response to them. Such hypotheses ostensibly create a situation where it is not possible to know that anything in the world exists. These hypotheses take the following form: The skeptical argument Where ''S'' is a subject, ''sp'' is a skeptical possibility, such as the brain in a vat hypothesis, and ''q'' is a knowledge claim about the world: :* If ''S'' doesn't know that not-''sp'', then ''S'' doesn't know t ...

Epistemology
Epistemology (; ), or the theory of knowledge, is the branch of philosophy concerned with knowledge. Epistemology is considered a major subfield of philosophy, along with other major subfields such as ethics, logic, and metaphysics. Epistemologists study the nature, origin, and scope of knowledge, epistemic justification, the rationality of belief, and various related issues. Debates in epistemology are generally clustered around four core areas: # The philosophical analysis of the nature of knowledge and the conditions required for a belief to constitute knowledge, such as truth and justification # Potential sources of knowledge and justified belief, such as perception, reason, memory, and testimony # The structure of a body of knowledge or justified belief, including whether all justified beliefs must be derived from justified foundational beliefs or whether justification requires only a coherent set of beliefs # Philosophical skepticism, which questions the possibili ...

Perception
Perception () is the organization, identification, and interpretation of sensory information in order to represent and understand the presented information or environment. All perception involves signals that go through the nervous system, which in turn result from physical or chemical stimulation of the sensory system.Goldstein (2009) pp. 5–7 Vision involves light striking the retina of the eye; smell is mediated by odor molecules; and hearing involves pressure waves. Perception is not only the passive receipt of these signals, but it is also shaped by the recipient's learning, memory, expectation, and attention. Gregory, Richard. "Perception" in Gregory, Zangwill (1987) pp. 598–601. Sensory input is a process that transforms this low-level information to higher-level information (e.g., extracts shapes for object recognition). The process that follows connects a person's concepts and expectations (or knowledge), restorative and selective mechanisms (such as ...

Determinism
Determinism is a philosophical view, where all events are determined completely by previously existing causes. Deterministic theories throughout the history of philosophy have developed from diverse and sometimes overlapping motives and considerations. The opposite of determinism is some kind of indeterminism (otherwise called nondeterminism) or randomness. Determinism is often contrasted with free will, although some philosophers claim that the two are compatible.For example, see Determinism is often used to mean ''causal determinism'', which in physics is known as cause-and-effect. This is the concept that events within a given paradigm are bound by causality in such a way that any state of an object or event is completely determined by its prior states. This meaning can be distinguished from other varieties of determinism mentioned below. Debates about determinism often concern the scope of determined systems; some maintain that the entire universe is a single determina ...

War And Peace
''War and Peace'' (russian: Война и мир, translit=Voyna i mir; pre-reform Russian: ; ) is a literary work by the Russian author Leo Tolstoy that mixes fictional narrative with chapters on history and philosophy. It was first published serially, then published in its entirety in 1869. It is regarded as Tolstoy's finest literary achievement and remains an internationally praised classic of world literature. The novel chronicles the French invasion of Russia and the impact of the Napoleonic era on Tsarist society through the stories of five Russian aristocratic families. Portions of an earlier version, titled ''The Year 1805'', were serialized in ''The Russian Messenger'' from 1865 to 1867 before the novel was published in its entirety in 1869.Knowles, A. V. ''Leo Tolstoy'', Routledge 1997. Tolstoy said that the best Russian literature does not conform to standards and hence hesitated to classify ''War and Peace'', saying it is "not a novel, even less is it a poem, and ...

Leo Tolstoy
Count Lev Nikolayevich TolstoyTolstoy pronounced his first name as , which corresponds to the romanization ''Lyov''. () (; russian: link=no, Лев Николаевич Толстой,In Tolstoy's day, his name was written as in pre-reformed Russian. ; ), usually referred to in English as Leo Tolstoy, was a Russian writer who is regarded as one of the greatest authors of all time. He received nominations for the Nobel Prize in Literature every year from 1902 to 1906 and for the Nobel Peace Prize in 1901, 1902, and 1909; the fact that he never won is a major controversy. Born to an aristocratic Russian family in 1828, Tolstoy's notable works include the novels ''War and Peace'' (1869) and ''Anna Karenina'' (1878), often cited as pinnacles of realist fiction. He first achieved literary acclaim in his twenties with his semi-autobiographical trilogy, ''Childhood'', '' Boyhood'', and ''Youth'' (1852–1856), and '' Sevastopol Sketches'' (1855), based upon his experiences in ...

Diogenes
Diogenes ( ; grc, Διογένης, Diogénēs ), also known as Diogenes the Cynic (, ) or Diogenes of Sinope, was a Greek philosopher and one of the founders of Cynicism (philosophy). He was born in Sinope, an Ionian colony on the Black Sea coast of Anatolia (Asia Minor''Diogenes of Sinope'' ) in 412 or 404 BC and died at Corinth in 323 BC., Plutarch, ''Moralia'', 717c. says that he died on the same day as Alexander the Great, which puts his death at 323 BC. Diogenes Laërtius's statement that Diogenes died "nearly 90" would put his year of birth at 412 BC. But Censorinus (''De die natali'', 15.2) says that he died at age 81, which puts his year of birth at 404 BC. The Suda puts his birth at the time of the Thirty Tyrants, which also gives 404 BC. Diogenes was a controversial figure. He was allegedly banished, or fled from, Sinope for debasement of currency. He was the son of the mintmaster of Sinope, and there is some debate as to whether or not he alone had debased the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Immaterialism
Subjective idealism, or empirical idealism, is a form of philosophical monism that holds that only minds and mental contents exist. It entails and is generally identified or associated with immaterialism, the doctrine that material things do not exist. Subjective idealism rejects dualism, neutral monism, and materialism; indeed, it is the contrary of eliminative materialism, the doctrine that all or some classes of mental phenomena (such as emotions, beliefs, or desires) do not exist, but are sheer illusions. Overview Subjective idealism is a fusion of phenomenalism or empiricism, which confers special status upon the immediately perceived, with idealism, which confers special status upon the mental. Idealism denies the knowability or existence of the non-mental, while phenomenalism serves to restrict the mental to the empirical. Subjective idealism thus identifies its mental reality with the world of ordinary experience, and does not comment on whether this reality is "divine ...

George Berkeley
George Berkeley (; 12 March 168514 January 1753) – known as Bishop Berkeley (Bishop of Cloyne of the Anglican Church of Ireland) – was an Anglo-Irish philosopher whose primary achievement was the advancement of a theory he called "immaterialism" (later referred to as " subjective idealism" by others). This theory denies the existence of material substance and instead contends that familiar objects like tables and chairs are ideas perceived by the mind and, as a result, cannot exist without being perceived. Berkeley is also known for his critique of abstraction, an important premise in his argument for immaterialism. In 1709, Berkeley published his first major work, '' An Essay Towards a New Theory of Vision'', in which he discussed the limitations of human vision and advanced the theory that the proper objects of sight are not material objects, but light and colour. This foreshadowed his chief philosophical work, ''A Treatise Concerning the Principles of Human Knowledg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Samuel Johnson
Samuel Johnson (18 September 1709 – 13 December 1784), often called Dr Johnson, was an English writer who made lasting contributions as a poet, playwright, essayist, moralist, critic, biographer, editor and lexicographer. The ''Oxford Dictionary of National Biography'' calls him "arguably the most distinguished man of letters in English history". Born in Lichfield, Staffordshire, he attended Pembroke College, Oxford until lack of funds forced him to leave. After working as a teacher, he moved to London and began writing for ''The Gentleman's Magazine''. Early works include ''Life of Mr Richard Savage'', the poems ''London'' and ''The Vanity of Human Wishes'' and the play ''Irene''. After nine years' effort, Johnson's '' A Dictionary of the English Language'' appeared in 1755, and was acclaimed as "one of the greatest single achievements of scholarship". Later work included essays, an annotated ''The Plays of William Shakespeare'', and the apologue ''The History of R ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

On Certainty
''On Certainty'' (german: Über Gewissheit, original spelling ) is a philosophical book composed from notes written by Ludwig Wittgenstein over four separate periods in the eighteen months before his death on 29 April 1951. He left his initial notes at the home of Elizabeth Anscombe, who linked them by theme with later passages in Wittgenstein's personal notebooks and (with G. H. von Wright), compiled them into a German/English parallel text book published in 1969. The translators were Denis Paul and Anscombe herself. (The editors also numbered and grouped the 676 passages; citations to the work are standardly given as OC1..OC676 rather than by page number.) The book's concerns are largely epistemological, a recurrent theme being that there are some things which must be exempt from doubt in order for human practices to be possible, including the activity of raising doubts: "A doubt that doubted everything would not be a doubt" (OC450). The book takes as its starting point the 'her ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wittgenstein
Ludwig Josef Johann Wittgenstein ( ; ; 26 April 1889 – 29 April 1951) was an Austrians, Austrian-British people, British philosopher who worked primarily in logic, the philosophy of mathematics, the philosophy of mind, and the philosophy of language. He is considered by some to be the greatest philosopher of the 20th century. From 1929 to 1947, Wittgenstein taught at the University of Cambridge. In spite of his position, during his entire life only one book of #Legacy, his philosophy was published, the 75-page ''Logisch-Philosophische Abhandlung'' (''Logical-Philosophical Treatise'', 1921), which appeared, together with an English translation, in 1922 under the Latin title ''Tractatus Logico-Philosophicus''. His only other published works were an article, "Some Remarks on Logical Form" (1929); a book review; and a children's dictionary. #Works, His voluminous manuscripts were edited and published posthumously.
