Universality (philosophy)In philosophy, universality or absolutism is the idea that universal facts exist and can be progressively discovered, as opposed to relativism, which asserts that all facts are relative to one's perspective. Absolutism and relativism have been explored at length in contemporary analytic philosophy. Also see Kantian and Platonist notions of "universal", which are considered by most philosophers to be separate notions. Moral universalism When used in the context of ethics, the meaning of universal refers to that which is true for "all similarly situated individuals".
Substantial formSubstantial form is a central philosophical concept in Aristotelianism and, afterwards, in Scholasticism. The form is the idea, existent or embodied in a being, that completes or actualizes the potentiality latent in the matter composing the being itself. For Aristotle, in fact, matter is the basis of all that exists; it comprises the potentiality of everything, but of itself is not actually anything. A determinate thing only comes into being when the potentiality in matter is converted into actuality; this is achieved by the substantial form.
Sum of LogicThe Summa Logicae ("Sum of Logic") is a textbook on logic by William of Ockham. It was written around 1323. Systematically, it resembles other works of medieval logic, organised under the basic headings of the Aristotelian Predicables, , terms, propositions, and syllogisms. These headings, though often given in a different order, represent the basic arrangement of scholastic works on logic. This work is important in that it contains the main account of Ockham's nominalism, a position related to the problem of universals.
Parmenides (dialogue)Parmenides (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.
Scotistic realismScotistic realism (also Scotist realism or Scotist formalism) is the Scotist position on the problem of universals. It is a form of moderate realism, which is sometimes referred to as 'scholastic realism'. The position maintains that universals exist both in particular objects and as concepts in the mind. The "problem of universals" was an ancient problem in metaphysics about whether universals exist. For John Duns Scotus, a Franciscan philosopher, theologian and Catholic priest, universals such as "greenness" and "goodness" exist in reality.
HaecceityHaecceity (hɛkˈsiːɪti,_hiːk-; from the Latin haecceitas, which translates as "thisness") is a term from medieval scholastic philosophy, first coined by followers of Duns Scotus to denote a concept that he seems to have originated: the irreducible determination of a thing that makes it this particular thing. Haecceity is a person's or object's thisness, the individualising difference between the concept "a man" and the concept "Socrates" (i.e., a specific person). In modern philosophy of physics, it is sometimes referred to as primitive thisness.
RoscellinusRoscelin of Compiègne (1050-1125), better known by his Latinized name Roscellinus Compendiensis or Rucelinus, was a French philosopher and theologian, often regarded as the founder of nominalism. Roscellinus was born in Compiègne, France. Little is known of his life, and knowledge of his doctrines is mainly derived from Anselm and Abelard. He studied at Soissons and Reims, was afterwards attached to the cathedral of Chartres and became canon of Compiègne. As a monk of Compiègne, he was teaching as early as 1087.
Trope (philosophy)Trope denotes figurative and metaphorical language and one which has been used in various technical senses. The term trope derives from the Greek τρόπος (tropos), "a turn, a change", related to the root of the verb τρέπειν (trepein), "to turn, to direct, to alter, to change"; this means that the term is used metaphorically to denote, among other things, metaphorical language. The term is also used in technical senses, which do not always correspond to its linguistic origin.
Relations (philosophy)Relations are ways in which things, the relata, stand to each other. Relations are in many ways similar to properties in that both characterize the things they apply to. Properties are sometimes treated as a special case of relations involving only one relatum. In philosophy (especially metaphysics), theories of relations are typically introduced to account for repetitions of how several things stand to each other. The concept of relation has a long and complicated history.
Allegory of the caveThe Allegory of the Cave, or Plato's Cave, is an allegory presented by the Greek philosopher Plato in his work Republic (514a–520a) to compare "the effect of education (παιδεία) and the lack of it on our 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.
