Tree Of Porphyry
The Tree of Porphyry (also known as ''scala praedicamentalis'') is a classic device for illustrating what is also called a "scale of being". It was suggested—if not first, then most famously in the European philosophical tradition—by the 3rd century CE Greek neoplatonist philosopher and logician Porphyry and revived through the translations of Boethius. Porphyry suggests the Porphyrian tree in his introduction (in Greek, "''Isagoge''") to Aristotle's Categories. Porphyry presented Aristotle's classification of categories in a way that was later adopted into tree-like diagrams of two-way divisions, which indicate that a species is defined by a genus and a differentia and that this logical process continues until the lowest species is reached, which can no longer be so defined. No illustrations or diagrams occur in editions of Porphyry's original work. But, diagrams were eventually made, and became associated with the scheme that Porphyry describes, following Aristotle. ...

Sophist (dialogue)
The ''Sophist'' ( el, Σοφιστής; la, SophistaHenri Estienne (ed.), ''Platonis opera quae extant omnia'', Vol. 1, 1578p. 217) is a Platonic dialogue from the philosopher's late period, most likely written in 360 BC. In it the interlocutors, led by Eleatic Stranger employ the method of division in order to classify and define the sophist and describe his essential attributes and differentia vis a vis the philosopher and statesman. Like its sequel, the ''Statesman'', the dialogue is unusual in that Socrates is present but plays only a minor role. Instead, the Eleatic Stranger takes the lead in the discussion. Because Socrates is silent, it is difficult to attribute the views put forward by the Eleatic Stranger to Plato, beyond the difficulty inherent in taking any character to be an author's "mouthpiece". Background The main objective of the dialogue is to identify what a sophist is and how a sophist differs from a philosopher and statesman. Because each seems distinguish ...

Hegelian Dialectic
Dialectic ( grc-gre, διαλεκτική, ''dialektikḗ''; related to dialogue; german: Dialektik), also known as the dialectical method, is a discourse between two or more people holding different points of view about a subject but wishing to establish the truth through reasoned argumentation. Dialectic resembles debate, but the concept excludes subjective elements such as emotional appeal and the modern pejorative sense of rhetoric. Dialectic may thus be contrasted with both the eristic, which refers to argument that aims to successfully dispute another's argument (rather than searching for truth), and the didactic method, wherein one side of the conversation teaches the other. Dialectic is alternatively known as ''minor logic'', as opposed to ''major logic'' or critique. Within Hegelianism, the word ''dialectic'' has the specialised meaning of a contradiction between ideas that serves as the determining factor in their relationship. Dialectical materialism, a theory ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Infima Species
In mathematics, the infimum (abbreviated inf; plural infima) of a subset S of a partially ordered set P is a greatest element in P that is less than or equal to each element of S, if such an element exists. Consequently, the term ''greatest lower bound'' (abbreviated as ) is also commonly used. The supremum (abbreviated sup; plural suprema) of a subset S of a partially ordered set P is the least element in P that is greater than or equal to each element of S, if such an element exists. Consequently, the supremum is also referred to as the ''least upper bound'' (or ). The infimum is in a precise sense dual to the concept of a supremum. Infima and suprema of real numbers are common special cases that are important in analysis, and especially in Lebesgue integration. However, the general definitions remain valid in the more abstract setting of order theory where arbitrary partially ordered sets are considered. The concepts of infimum and supremum are close to minimum and max ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phenomenology Of Spirit
''The Phenomenology of Spirit'' (german: Phänomenologie des Geistes) is the most widely-discussed philosophical work of Georg Wilhelm Friedrich Hegel; its German title can be translated as either ''The Phenomenology of Spirit'' or ''The Phenomenology of Mind''. Hegel described the work, published in 1807, as an "exposition of the coming to be of knowledge". This is explicated through a necessary self-origination and dissolution of "the various shapes of spirit as stations on the way through which spirit becomes pure knowledge". The book marked a significant development in German idealism after Immanuel Kant. Focusing on topics in metaphysics, epistemology, ontology, ethics, philosophy of history, history, philosophy of religion, religion, philosophy of perception, perception, consciousness, existence, logic, and political philosophy, it is where Hegel develops his concepts of dialectic (including the master–slave dialectic, lord-bondsman dialectic), absolute idealism, ethical ...

Georg Wilhelm Friedrich Hegel
Georg Wilhelm Friedrich Hegel (; ; 27 August 1770 – 14 November 1831) was a German philosopher. He is one of the most important figures in German idealism and one of the founding figures of modern Western philosophy. His influence extends across the entire range of contemporary philosophical topics, from metaphysical issues in epistemology and ontology, to political philosophy, the philosophy of history, philosophy of art, philosophy of religion, and the history of philosophy. Born in 1770 in Stuttgart during the transitional period between the Enlightenment and the Romantic movement in the Germanic regions of Europe, Hegel lived through and was influenced by the French Revolution and the Napoleonic wars. His fame rests chiefly upon ''The Phenomenology of Spirit'', ''The Science of Logic'', and his lectures at the University of Berlin on topics from his ''Encyclopedia of the Philosophical Sciences''. Throughout his work, Hegel strove to address and correct the probl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Summum Genus
Summum is a religion and philosophy that began in 1975 as a result of American citizen Claude "Corky" Nowell's claimed encounter with beings he described as "Summa Individuals". According to Nowell, these beings presented him with concepts regarding the nature of creation, concepts that have always existed and are continually re-introduced to humankind by advanced beings who work along the pathways of creation. As a result of his experience, Nowell founded Summum in order to share the "gift" he received with others. In 1980, as a reflection of his newfound path, he changed his name to Summum Bonum Amon Ra, but news stories indicate he went by Corky Ra. Summum religious practices draw upon both Ancient Egyptian religion and the Hebrew prophet Moses. Basis of the philosophy Summum's philosophy stems from what it considers to be principles of nature that cannot be attributed to any person. These principles flower in different forms and were outlined before in the wr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Differentia
In scholastic logic, differentia is one of the predicables. It is that part of a definition which is predicable in a given genus only of the definiendum; or the corresponding " metaphysical part" of the object. Origin Plato implicitly employed the concept of differentia when he conceived his method of ''diairesis''. Aristotle was the first to use the term ''diaphora'' (διαφορά) in a systematic fashion; but he had no explicit theory about it, and his understanding of the term is controversial. A theory was only provided by Porphyry's explicit treatment of the predicables presented in his ''Isagoge''. The elaborate scholastic theory of the predicables evolved οn the basis of Boethius' translation of the Isagoge, where the Greek term ''diaphora'' was rendered in Latin as "differentia". In ancient Greek ''adiaphora'' - is the negation of ''diaphora'' - is an important term in Hellenistic philosophy. However, only in Pyrrhonism does it appear to be a denial of Aristotle's ...

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Parmenides (dialogue)
''Parmenides'' ( el, Παρμενίδης) is one of the dialogues of Plato. It is widely considered to be one of the most challenging and enigmatic of Plato's dialogues. The ''Parmenides'' purports to be an account of a meeting between the two great philosophers of the Eleatic school, Parmenides and Zeno of Elea, and a young Socrates. The occasion of the meeting was the reading by Zeno of his treatise defending Parmenidean monism against those partisans of plurality who asserted that Parmenides' supposition that there is a one gives rise to intolerable absurdities and contradictions. The dialogue is set during a supposed meeting between Parmenides and Zeno of Elea in Socrates' hometown of Athens. This dialogue is chronologically the earliest of all as Socrates is only nineteen years old here. It is also notable that he takes the position of the student here while Parmenides serves as the lecturer. The dialogue is likely fictitious. Discussion with Socrates The heart of the ...
