Logica Nova
In the history of logic, the term ''logica nova'' (Latin, meaning "new logic") refers to a subdivision of the logical tradition of Western Europe, as it existed around the middle of the twelfth century. The ''Logica vetus'' ("old logic") referred to works of Aristotle that had long been known and studied in the Latin West, whereas the ''Logica nova'' referred to forms of logic derived from Aristotle's works which had been unavailable until they were translated by James of Venice in the 12th century. Study of the ''Logica nova'' was part of the Renaissance of the 12th century. Overview The division of works was as follows: *''Logica vetus'' (sometimes ''ars vetus'') **The '' Categories'' **The '' De Interpretatione'' **The '' Isagoge'' of Porphyry **The ''Liber sex principiorum'', an anonymous commentary on the latter part of the ''Categories'' that has often been attributed to Gilbert de la Porrée *Sometimes included are works of Boethius **The ''De topicis differentiis'' **Th ...

History Of Logic
The history of logic deals with the study of the development of the science of valid inference (logic). Formal logics developed in ancient times in India, China, and Greece. Greek methods, particularly Aristotelian logic (or term logic) as found in the '' Organon'', found wide application and acceptance in Western science and mathematics for millennia.Boehner p. xiv The Stoics, especially Chrysippus, began the development of predicate logic. Christian and Islamic philosophers such as Boethius (died 524), Ibn Sina (Avicenna, died 1037) and William of Ockham (died 1347) further developed Plato's logic in the Middle Ages, reaching a high point in the mid-fourteenth century, with Jean Buridan. The period between the fourteenth century and the beginning of the nineteenth century saw largely decline and neglect, and at least one historian of logic regards this time as barren.Oxford Companion p. 498; Bochenski, Part I Introduction, ''passim'' Empirical methods ruled the day, as evidenc ...

Topics (Aristotle)
The ''Topics'' ( grc-gre, Τοπικά; la, Topica) is the name given to one of Aristotle's six works on logic collectively known as the '' Organon''. The treatise presents the art of dialectic — the invention and discovery of arguments in which the propositions rest upon commonly held opinions or endoxa ( in Greek). ''Topoi'' () are "places" from which such arguments can be discovered or invented. What is a topic? In his treatise ''Topics'', Aristotle does not explicitly define topic, though it is "at least primarily a strategy for argument not infrequently justified or explained by a principle." He characterises it in the ''Rhetoric'' thus: "I call the same thing element and topic; for an element or a topic is a heading under which many enthymemes fall." By element, he means a general form under which enthymemes of the same type can be included. Thus, a topic is a general argument source, from which the individual arguments are instances, and is a template from which many ...

Latin Translations Of The 12th Century
Latin translations of the 12th century were spurred by a major search by European scholars for new learning unavailable in western Europe at the time; their search led them to areas of southern Europe, particularly in central Spain and Sicily, which recently had come under Christian rule following their reconquest in the late 11th century. These areas had been under Muslim rule for a considerable time, and still had substantial Arabic-speaking populations to support their search. The combination of this accumulated knowledge and the substantial numbers of Arabic-speaking scholars there made these areas intellectually attractive, as well as culturally and politically accessible to Latin scholars. A typical story is that of Gerard of Cremona (c. 1114–87), who is said to have made his way to Toledo, well after its reconquest by Christians in 1085, because he Many Christian theologians were highly suspicious of ancient philosophies and especially of the attempts to synthesize th ...

Johannes Clauberg
Johannes Clauberg (24 February 1622 – 31 January 1665) was a German theologian and philosopher. Clauberg was the founding Rector of the first University of Duisburg, where he taught from 1655 to 1665. He is known as a "scholastic cartesian". Biography He was born in Solingen, and educated in the Aristotelian tradition in Köln, Moers and Bremen, then in Groningen, where he discovered what came to be called the reformed variation of Aristotelianism. He gave his first disputations in Groningen under the supervision of Tobias Andreae. His first treatise in metaphysics was written in those student years: ''Elementa philosophiae sive Ontosophia'' (1647). Travelling in France and England, he came to study the Cartesian philosophy under Johannes de Raey at Leiden. In 1649, he became professor of philosophy and theology at Herborn, but subsequently (1651), in consequence of the jealousy of his colleagues, accepted an invitation to a similar post at Duisburg. Clauberg was one ...

Paul Of Venice
Paul of Venice (or Paulus Venetus; 1369–1429) was a Catholic philosopher, theologian, logician and metaphysician of the Order of Saint Augustine. Life Paul was born, according to the chroniclers of his order, at Udine, about 1369 and died at Venice on 15 June 1429, as Paolo Nicoletti. He joined the Augustinian Order at the age of 14, at the convent of Santo Stefano in Venice. In 1390 he is said to have been sent to Oxford for his studies in theology, but returned to Italy, and finished his course at the University of Padua, becoming a Doctor of Arts and Theology in 1405. He lectured in the Universities of Padua, Siena, Perugia, and Bologna during the first quarter of the fifteenth century. He was also a teacher to Paolo da Pergola. Paul was also appointed Prior General of the Augustinian Order in 1409 by Pope Gregory XII, and also served as an ambassador to the Republic of Venice. Paul was one of the theologians called to Rome in 1427 by Pope Martin V to defend the orthodoxy ...

Ramón Lull
Ramon Llull (; c. 1232 – c. 1315/16) was a philosopher, theologian, poet, missionary, and Christian apologist from the Kingdom of Majorca. He invented a philosophical system known as the ''Art'', conceived as a type of universal logic to prove the truth of Christian doctrine to interlocutors of all faiths and nationalities. The ''Art'' consists of a set of general principles and combinatorial operations. It is illustrated with diagrams. A prolific writer, he is also known for his literary works written in Catalan, which he composed to make his ''Art'' accessible to a wider audience. In addition to Catalan and Latin he also probably wrote in Arabic (although no texts in Arabic survive). His books were translated into Occitan, French, and Castilian during his lifetime. Although his work did not enjoy huge success during his lifetime, he has had a rich and continuing reception. In the early modern period his name became associated with alchemical works. More recently he has ...

Pontifical University Of Saint Thomas Aquinas
A pontifical ( la, pontificale) is a Christian liturgical book containing the liturgies that only a bishop may perform. Among the liturgies are those of the ordinal for the ordination and consecration of deacons, priests, and bishops to Holy Orders. While the '' Roman Pontifical'' and closely related '' Ceremonial of Bishops'' of the Roman Rite are the most common, pontificals exist in other liturgical traditions. History Pontificals in Latin Christianity first developed from sacramentaries by the 8th century. Besides containing the texts of exclusively episcopal liturgies such as the Pontifical High Mass, liturgies that other clergymen could celebrate were also present. The contents varied throughout the Middle Ages, but eventually a pontifical only contained those liturgies a bishop could perform. The ''Pontificale Egberti'', a pontifical that once belonged to and was perhaps authored by Ecgbert of York, is regarded as one of the most notable early pontificals and ma ...

Santa Sabina
The Basilica of Saint Sabina ( la, Basilica Sanctae Sabinae, it, Basilica di Santa Sabina all'Aventino) is a historic church on the Aventine Hill in Rome, Italy. It is a titular minor basilica and mother church of the Roman Catholic Order of Preachers, better known as the Dominicans. Santa Sabina is the oldest extant ecclesiastical basilica in Rome that preserves its original colonnaded rectangular plan with apse and architectural style. Its decorations have been restored to their original restrained design. Other basilicas, such as Santa Maria Maggiore, have been ornately decorated in later centuries. Because of its simplicity, the Santa Sabina represents the adaptation of the architecture of the roofed Roman forum or basilica to the basilica churches of Christendom. It is especially well-known for its cypress wood doors carved in AD 430-432 with Biblical scenes, the most famous being the first known publicly displayed depiction of the crucifixion of Jesus Christ and the two th ...

Dominican Order
The Order of Preachers ( la, Ordo Praedicatorum) abbreviated OP, also known as the Dominicans, is a Catholic mendicant order of Pontifical Right for men founded in Toulouse, France, by the Spanish priest, saint and mystic Dominic of Caleruega. It was approved by Pope Honorius III via the papal bull '' Religiosam vitam'' on 22 December 1216. Members of the order, who are referred to as ''Dominicans'', generally carry the letters ''OP'' after their names, standing for ''Ordinis Praedicatorum'', meaning ''of the Order of Preachers''. Membership in the order includes friars, nuns, active sisters, and lay or secular Dominicans (formerly known as tertiaries). More recently there has been a growing number of associates of the religious sisters who are unrelated to the tertiaries. Founded to preach the Gospel and to oppose heresy, the teaching activity of the order and its scholastic organisation placed the Preachers in the forefront of the intellectual life of the ...

Organon
The ''Organon'' ( grc, Ὄργανον, meaning "instrument, tool, organ") is the standard collection of Aristotle's six works on logical analysis and dialectic. The name ''Organon'' was given by Aristotle's followers, the Peripatetics. The six works are as follows: Constitution of the texts The order of the works is not chronological (which is now hard to determine) but was deliberately chosen by Theophrastus to constitute a well-structured system. Indeed, parts of them seem to be a scheme of a lecture on logic. The arrangement of the works was made by Andronicus of Rhodes around 40 BC. Aristotle's ''Metaphysics'' has some points of overlap with the works making up the ''Organon'' but is not traditionally considered part of it; additionally, there are works on logic attributed, with varying degrees of plausibility, to Aristotle that were not known to the Peripatetics. # The '' Categories'' (Latin: ) introduces Aristotle's 10-fold classification of that which exists: su ...

Sophisms (Aristotle)
''Sophistical Refutations'' ( el, Σοφιστικοὶ Ἔλεγχοι, Sophistikoi Elenchoi; la, De Sophisticis Elenchis) is a text in Aristotle's ''Organon'' in which he identified thirteen fallacies.Sometimes listed as twelve. According to Aristotle, this is the first work to treat the subject of deductive reasoning in ancient Greece (''Soph. Ref.'', 34, 183b34 ff.). Overview ''On Sophistical Refutations'' consists of 34 chapters. The book naturally falls in two parts: chapters concerned with tactics for the Questioner (3–8 and 12–15) and chapters concerned with tactics for the Answerer (16–32). Besides, there is an introduction (1–2), an interlude (9–11), and a conclusion (33–34). Fallacies identified The fallacies Aristotle identifies in Chapter 4 (formal fallacies) and 5 (informal fallacies) of this book are the following: :Fallacies in the language or formal fallacies (''in dictionem'') # Equivocation # Amphibology # Composition # Division # Accent # Figu ...
