Cogito Ergo Sum
The Latin , usually translated into English as "I think, therefore I am", is the "first principle" of René Descartes's philosophy. He originally published it in French as , in his 1637 ''Discourse on the Method'', so as to reach a wider audience than Latin would have allowed. It later appeared in Latin in his ''Principles of Philosophy'', and a similar phrase also featured prominently in his ''Meditations on First Philosophy''. The dictum is also sometimes referred to as the cogito. As Descartes explained in a margin note, "we cannot doubt of our existence while we doubt." In the posthumously published ''The Search for Truth by Natural Light'', he expressed this insight as ("I doubt, therefore I am — or what is the same — I think, therefore I am").. Antoine Léonard Thomas, in a 1765 essay in honor of Descartes presented it as ("I doubt, therefore I think, therefore I am"). Descartes's statement became a fundamental element of Western philosophy, as it purported to pr ...

Latin
Latin (, or , ) is a classical language belonging to the Italic branch of the Indo-European languages. Latin was originally a dialect spoken in the lower Tiber area (then known as Latium) around present-day Rome, but through the power of the Roman Republic it became the dominant language in the Italian region and subsequently throughout the Roman Empire. Even after the fall of Western Rome, Latin remained the common language of international communication, science, scholarship and academia in Europe until well into the 18th century, when other regional vernaculars (including its own descendants, the Romance languages) supplanted it in common academic and political usage, and it eventually became a dead language in the modern linguistic definition. Latin is a highly inflected language, with three distinct genders (masculine, feminine, and neuter), six or seven noun cases (nominative, accusative, genitive, dative, ablative, and vocative), five declensions, four verb conjuga ...

Certainty
Certainty (also known as epistemic certainty or objective certainty) is the epistemic property of beliefs which a person has no rational grounds for doubting. One standard way of defining epistemic certainty is that a belief is certain if and only if the person holding that belief could not be mistaken in holding that belief. Other common definitions of certainty involve the indubitable nature of such beliefs or define certainty as a property of those beliefs with the greatest possible justification. Certainty is closely related to knowledge, although contemporary philosophers tend to treat knowledge as having lower requirements than certainty. Importantly, epistemic certainty is not the same thing as psychological certainty (also known as subjective certainty or certitude), which describes the highest degree to which a person could be convinced that something is true. While a person may be completely convinced that a particular belief is true, and might even be psychologicall ...

Gisbertus Voetius
Gisbertus Voetius ( Latinized version of the Dutch name Gijsbert Voet ; 3 March 1589 – 1 November 1676) was a Dutch Calvinist theologian. Life He was born at Heusden, in the Dutch Republic, studied at Leiden, and in 1611 became Protestant pastor of Vlijmen, whence in 1617 he returned to Heusden. In 1619, he played an influential part in the Synod of Dort, at which he was the youngest delegate. In 1634, Voetius was made professor of theology and Oriental science at the University of Utrecht. Three years later he became pastor of the Utrecht congregation. He was an advocate of a strong form of Calvinism (Gomarism) against the Arminians. The city of Utrecht perpetuated his memory by giving his name to the street in which he had lived. Utrecht controversy with Descartes In March 1642, while serving as rector of the University of Utrecht, Voetius persuaded the university's academic senate to issue a formal condemnation of the Cartesian philosophy and its local defender, Henricus R ...

Martin Schoock
Martin Schoock (1 April 1614–1669) was a Dutch academic and polymath. Life He was born in Utrecht. His grandfather Anton van Voorst taught him Latin. His parents were Remonstrants and intended him for the law; he studied theology and philosophy from 1632 in Leiden under Antonius Walaeus. As a student of Gisbertus Voetius he acquired a doctorate in philosophy around 1636. About 1638 he became professor in classical literature, rhetoric and history at the University of Deventer, and then in 1640 in the University of Groningen professor in logic and physics. Schoock was combative and brought difficulties on himself. Descartes at one point felt Schoock had libeled him and complained to the French ambassador. Schoock was arrested and spent two days in jail. He exonerated himself by in effect proving that Voetius had put him up to it, citing letters from his former professor. After the death of his first wife, Angelica van Merck, with whom he had seven sons and a daughter, he c ...

Victor Cousin
Victor Cousin (; 28 November 179214 January 1867) was a French philosopher. He was the founder of "eclecticism", a briefly influential school of French philosophy that combined elements of German idealism and Scottish Common Sense Realism. As the administrator of public instruction for over a decade, Cousin also had an important influence on French educational policy. Biography Early years The son of a watchmaker, he was born in Paris, in the Quartier Saint-Antoine. At the age of ten he was sent to the local grammar school, the Lycée Charlemagne, where he studied until he was eighteen. ''Lycées'' being organically linked to the University of France and its Faculties since their Napoleonic institution (the ''baccalauréat'' was awarded by juries made of university professors) Cousin was "crowned" in the ancient hall of the Sorbonne for a Latin oration he wrote which owned him a first prize at the ''concours général'', a competition between the best pupils at ''lycées'' ...

Marginalia
Marginalia (or apostils) are marks made in the margins of a book or other document. They may be scribbles, comments, glosses (annotations), critiques, doodles, drolleries, or illuminations. Biblical manuscripts Biblical manuscripts have liturgical notes at the margin, for liturgical use. Numbers of texts' divisions are given at the margin (, Ammonian Sections, Eusebian Canons). There are some scholia, corrections and other notes usually made later by hand in the margin. Marginalia may also be of relevance because many ancient or medieval writers of marginalia may have had access to other relevant texts that, although they may have been widely copied at the time, have since then been lost due to wars, prosecution, or censorship. As such, they might give clues to an earlier, more widely known context of the extant form of the underlying text than is currently appreciated. For this reason, scholars of ancient texts usually try to find as many still existing manuscripts of the ...

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 ...

Modern French
French ( or ) is a Romance language of the Indo-European family. It descended from the Vulgar Latin of the Roman Empire, as did all Romance languages. French evolved from Gallo-Romance, the Latin spoken in Gaul, and more specifically in Northern Gaul. Its closest relatives are the other langues d'oïl—languages historically spoken in northern France and in southern Belgium, which French (Francien) largely supplanted. French was also influenced by native Celtic languages of Northern Roman Gaul like Gallia Belgica and by the ( Germanic) Frankish language of the post-Roman Frankish invaders. Today, owing to France's past overseas expansion, there are numerous French-based creole languages, most notably Haitian Creole. A French-speaking person or nation may be referred to as Francophone in both English and French. French is an official language in 29 countries across multiple continents, most of which are members of the ''Organisation internationale de la Francophonie'' (OI ...

Middle French
Middle French (french: moyen français) is a historical division of the French language that covers the period from the 14th to the 16th century. It is a period of transition during which: * the French language became clearly distinguished from the other competing Oïl languages, which are sometimes subsumed within the concept of Old French () * the French language was imposed as the official language of the Kingdom of France in place of Latin and other Oïl and Occitan languages * the literary development of French prepared the vocabulary and grammar for the Classical French () spoken in the 17th and 18th centuries. It is the first version of French that is largely intelligible to Modern French speakers, contrary to Old French. History The most important change found in Middle French is the complete disappearance of the noun declension system (already underway for centuries). There is no longer a distinction between nominative and oblique forms of nouns, and plurals are indi ...

Pierre Gassendi
Pierre Gassendi (; also Pierre Gassend, Petrus Gassendi; 22 January 1592 – 24 October 1655) was a French philosopher, Catholic priest, astronomer, and mathematician. While he held a church position in south-east France, he also spent much time in Paris, where he was a leader of a group of free-thinking intellectuals. He was also an active observational scientist, publishing the first data on the transit of Mercury in 1631. The lunar crater Gassendi is named after him. He wrote numerous philosophical works, and some of the positions he worked out are considered significant, finding a way between skepticism and dogmatism. Richard Popkin indicates that Gassendi was one of the first thinkers to formulate the modern "scientific outlook", of moderated skepticism and empiricism. He clashed with his contemporary Descartes on the possibility of certain knowledge. His best known intellectual project attempted to reconcile Epicurean atomism with Christianity.

Self
The self is an individual as the object of that individual’s own reflective consciousness. Since the ''self'' is a reference by a subject to the same subject, this reference is necessarily subjective. The sense of having a self—or ''selfhood''—should, however, not be confused with subjectivity itself. Ostensibly, this sense is directed outward from the subject to refer inward, back to its "self" (or itself). Examples of psychiatric conditions where such "sameness" may become broken include depersonalization, which sometimes occurs in schizophrenia: the self appears different from the subject. The first-person perspective distinguishes selfhood from personal identity. Whereas "identity" is (literally) sameness and may involve categorization and labeling, selfhood implies a first-person perspective and suggests potential uniqueness. Conversely, we use "person" as a third-person reference. Personal identity can be impaired in late-stage Alzheimer's disease and in other neurode ...
