Brain-in-a-vat
In philosophy, the brain in a vat (BIV) is a scenario used in a variety of thought experiments intended to draw out certain features of human conceptions of knowledge, reality, truth, mind, consciousness, and meaning. It is a modern incarnation of René Descartes's evil demon thought experiment, originated by Gilbert Harman. Found in many science fiction stories, it outlines a scenario in which a mad scientist, machine, or other entity might remove a person's brain from the body, suspend it in a vat of life-sustaining liquid, and connect its neurons by wires to a supercomputer that would provide it with electrical impulses identical to those a brain normally receives. According to such stories, the computer would then be simulating reality (including appropriate responses to the brain's own output) and the "disembodied" brain would continue to have perfectly normal conscious experiences, such as those of a person with an embodied brain, without these being related to objec ...

Philosophical Skepticism
Philosophical skepticism ( UK spelling: scepticism; from Greek σκέψις ''skepsis'', "inquiry") is a family of philosophical views that question the possibility of knowledge. It differs from other forms of skepticism in that it even rejects very plausible knowledge claims that belong to basic common sense. Philosophical skeptics are often classified into two general categories: Those who deny all possibility of knowledge, and those who advocate for the suspension of judgment due to the inadequacy of evidence. This distinction is modeled after the differences between the Academic skeptics and the Pyrrhonian skeptics in ancient Greek philosophy. In the latter sense, skepticism is understood as a way of life that helps the practitioner achieve inner peace. Some types of philosophical skepticism reject all forms of knowledge while others limit this rejection to certain fields, for example, to knowledge about moral doctrines or about the external world. Some theorists criti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Meditations On First Philosophy
''Meditations on First Philosophy, in which the existence of God and the immortality of the soul are demonstrated'' ( la, Meditationes de Prima Philosophia, in qua Dei existentia et animæ immortalitas demonstratur) is a philosophical treatise by René Descartes first published in Latin in 1641. The French translation (by the Duke of Luynes with Descartes' supervision) was published in 1647 as ''Méditations Métaphysiques''. The title may contain a misreading by the printer, mistaking ''animae immortalitas'' for ''animae immaterialitas'', as suspected by A. Baillet. The book is made up of six meditations, in which Descartes first discards all belief in things that are not absolutely certain, and then tries to establish what can be known for sure. He wrote the meditations as if he had meditated for six days: each meditation refers to the last one as "yesterday". (In fact, Descartes began work on the ''Meditations'' in 1639.) One of the most influential philosophical texts ever w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zhuangzi (book)
The ''Zhuangzi'' (Chinese: , historically romanized ''Chuang Tzŭ'') is an ancient Chinese text from the late Warring States period (476221) which contains stories and anecdotes that exemplify the carefree nature of the ideal Taoist sage. Named for its traditional author, "Master Zhuang" (Zhuangzi), the ''Zhuangzi'' is one of the two foundational texts of Taoism, along with the ''Tao Te Ching''. The ''Zhuangzi'' consists of a large collection of anecdotes, allegories, parables, and fables, which are often humorous or irreverent. Its main themes are of spontaneity in action and of freedom from the human world and its conventions. The fables and anecdotes in the text attempt to illustrate the falseness of human distinctions between good and bad, large and small, life and death, and human and nature. While other ancient Chinese philosophers focused on moral and personal duty, Zhuangzi promoted carefree wandering and becoming one with "the Way" (''Dào'' ) by following nature. T ...

Zhuang Zhou
Zhuang Zhou (), commonly known as Zhuangzi (; ; literally "Master Zhuang"; also rendered in the Wade–Giles romanization as Chuang Tzu), was an influential Chinese philosopher who lived around the 4th century BCE during the Warring States period, a period of great development in Chinese philosophy, the Hundred Schools of Thought. He is credited with writing—in part or in whole—a work known by his name, the ''Zhuangzi'', which is one of the foundational texts of Taoism. Life The only account of the life of Zhuangzi is a brief sketch in chapter 63 of Sima Qian's ''Records of the Grand Historian'', and most of the information it contains seems to have simply been drawn from anecdotes in the ''Zhuangzi'' itself. In Sima's biography, he is described as a minor official from the town of Meng (in modern Anhui) in the state of Song, living in the time of King Hui of Liang and King Xuan of Qi (late fourth century BC). Sima Qian writes that Chuang-Tze was especially influe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Allegory Of The Cave
The Allegory of the Cave, or Plato's Cave, is an allegory presented by the Ancient Greece, Greek philosopher Plato in his work ''Republic (Plato), Republic'' (514a–520a) to compare "the effect of education (Wiktionary:παιδεία, παιδεία) and the lack of it on our physis, nature". It is written as a dialogue between Plato's brother Glaucon and his mentor Socrates, narrated by the latter. The allegory is presented after the analogy of the sun (508b–509c) and the analogy of the divided line (509d–511e). In the allegory "The Cave," Plato describes a group of people who have lived chained to the wall of a cave all their lives, facing a blank wall. The people watch shadows projected on the wall from objects passing in front of a fire behind them and give names to these shadows. The shadows are the prisoners' reality, but are not accurate representations of the real world. The shadows represent the fragment of reality that we can normally perceive through our senses, ...

Plato
Plato ( ; grc-gre, Πλάτων ; 428/427 or 424/423 – 348/347 BC) was a Greek philosopher born in Athens during the Classical period in Ancient Greece. He founded the Platonist school of thought and the Academy, the first institution of higher learning on the European continent. Along with his teacher, Socrates, and his student, Aristotle, Plato is a central figure in the history of Ancient Greek philosophy and the Western and Middle Eastern philosophies descended from it. He has also shaped religion and spirituality. The so-called neoplatonism of his interpreter Plotinus greatly influenced both Christianity (through Church Fathers such as Augustine) and Islamic philosophy (through e.g. Al-Farabi). In modern times, Friedrich Nietzsche diagnosed Western culture as growing in the shadow of Plato (famously calling Christianity "Platonism for the masses"), while Alfred North Whitehead famously said: "the safest general characterization of the European philosophical tra ...

Maya (illusion)
''Maya'' (; Devanagari: , IAST: ), literally "illusion" or "magic", has multiple meanings in Indian philosophies depending on the context. In later Vedic texts, connotes a "magic show, an illusion where things appear to be present but are not what they seem"; the principle which shows "attributeless Absolute" as having "attributes". also connotes that which "is constantly changing and thus is spiritually unreal" (in opposition to an unchanging Absolute, or Brahman), and therefore "conceals the true character of spiritual reality".Lynn Foulston and Stuart Abbott (2009), ''Hindu Goddesses: Beliefs and Practices'', Sussex Academic Press, , pp. 14-16. In the Advaita Vedanta school of Hindu philosophy, , "appearance", is "the powerful force that creates the cosmic illusion that the phenomenal world is real." In this nondualist school, at the individual level appears as the lack of knowledge () of the real Self, ''Atman-Brahman'', mistakingly identifying with the body-mind comp ...

Hinduism
Hinduism () is an Indian religion or '' dharma'', a religious and universal order or way of life by which followers abide. As a religion, it is the world's third-largest, with over 1.2–1.35 billion followers, or 15–16% of the global population, known as Hindus. The word ''Hindu'' is an exonym, and while Hinduism has been called the oldest religion in the world, many practitioners refer to their religion as '' Sanātana Dharma'' ( sa, सनातन धर्म, lit='the Eternal Dharma'), a modern usage, which refers to the idea that its origins lie beyond human history, as revealed in the Hindu texts. Another endonym is ''Vaidika dharma'', the dharma related to the Vedas. Hinduism is a diverse system of thought marked by a range of philosophies and shared concepts, rituals, cosmological systems, pilgrimage sites, and shared textual sources that discuss theology, metaphysics, mythology, Vedic yajna, yoga, agamic rituals, and temple building, among other to ...

Philosophy Of Language
In analytic philosophy, philosophy of language investigates the nature of language and the relations between language, language users, and the world. Investigations may include inquiry into the nature of meaning, intentionality, reference, the constitution of sentences, concepts, learning, and thought. Gottlob Frege and Bertrand Russell were pivotal figures in analytic philosophy's "linguistic turn". These writers were followed by Ludwig Wittgenstein ('' Tractatus Logico-Philosophicus''), the Vienna Circle, logical positivists, and Willard Van Orman Quine. In continental philosophy, language is not studied as a separate discipline. Rather, it is an inextricable part of many other areas of thought, such as phenomenology, structural semiotics, language of mathematics, hermeneutics, existentialism, deconstruction and critical theory. History Ancient philosophy In the West, inquiry into language stretches back to the 5th century BC with Socrates, Plato, Aristotl ...

Metaphysics
Metaphysics is the branch of philosophy that studies the fundamental nature of reality, the first principles of being, identity and change, space and time, causality, necessity, and possibility. It includes questions about the nature of consciousness and the relationship between mind and matter, between substance and attribute, and between potentiality and actuality. The word "metaphysics" comes from two Greek words that, together, literally mean "after or behind or among he study ofthe natural". It has been suggested that the term might have been coined by a first century CE editor who assembled various small selections of Aristotle's works into the treatise we now know by the name ''Metaphysics'' (μετὰ τὰ φυσικά, ''meta ta physika'', 'after the ''Physics'' ', another of Aristotle's works). Metaphysics studies questions related to what it is for something to exist and what types of existence there are. Metaphysics seeks to answer, in an abstract and fu ...

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 ...
