De Arte Combinatoria
The ''Dissertatio de arte combinatoria'' ("Dissertation on the Art of Combinations" or "On the Combinatorial Art") is an early work by Gottfried Leibniz published in 1666 in Leipzig. It is an extended version of his first doctoral dissertation, written before the author had seriously undertaken the study of mathematics.Gottfried Wilhelm Leibniz. ''Hauptschriften zur Grundlegung der Philosophie. Zur allgemeinen Charakteristik.'' ''Philosophische Werke'' Band 1. p. 32. Translated in German by Artur Buchenau. Published, reviewed and added an introduction and notes by Ernst Cassirer. Hamburg: Felix Meiner, 1966, p. 32. The booklet was reissued without Leibniz' consent in 1690, which prompted him to publish a brief explanatory notice in the ''Acta Eruditorum''. During the following years he repeatedly expressed regrets about its being circulated as he considered it immature.Leibniz complained to various correspondents, e.g., to Morell (1 October 1697) or to Meier (23 January 1699); see ' ...

De Sphaera Mundi
''De sphaera mundi'' (Latin title meaning ''On the Sphere of the World'', sometimes rendered ''The Sphere of the Cosmos''; the Latin title is also given as ''Tractatus de sphaera'', ''Textus de sphaera'', or simply ''De sphaera'') is a medieval introduction to the basic elements of astronomy written by Johannes de Sacrobosco (John of Holywood) c. 1230. Based heavily on Ptolemy's ''Almagest'', and drawing additional ideas from Islamic astronomy, it was one of the most influential works of pre- Copernican astronomy in Europe. Reception Sacrobosco's ''De sphaera mundi'' was the most successful of several competing thirteenth-century textbooks on this topic. It was used in universities for hundreds of years and the manuscript copied many times before the invention of the printing press; hundreds of manuscript copies have survived. The first printed edition appeared in 1472 in Ferrara, and at least 84 editions were printed in the next two hundred years. The work was frequently supplem ...

This is the first year to be designated as an ''Annus mirabilis'', in John Dryden's 1667 poem so titled, celebrating England's failure to be beaten either by the Dutch or by fire. It is the only year to contain each Roman numeral once in descending order (1000(M)+500(D)+100(C)+50(L)+10(X)+5(V)+1(I) = 1666).

Philosophy Of Language Literature
Philosophy (from , ) is the systematized study of general and fundamental questions, such as those about existence, reason, knowledge, values, mind, and language. Such questions are often posed as problems to be studied or resolved. Some sources claim the term was coined by Pythagoras ( BCE), although this theory is disputed by some. Philosophical methods include questioning, critical discussion, rational argument, and systematic presentation. in . Historically, ''philosophy'' encompassed all bodies of knowledge and a practitioner was known as a '' philosopher''."The English word "philosophy" is first attested to , meaning "knowledge, body of knowledge." "natural philosophy," which began as a discipline in ancient India and Ancient Greece, encompasses astronomy, medicine, and physics. For example, Newton's 1687 '' Mathematical Principles of Natural Philosophy'' later became classified as a book of physics. In the 19th century, the growth of modern research univers ...

Combinatorics
Combinatorics is an area of mathematics primarily concerned with counting, both as a means and an end in obtaining results, and certain properties of finite structures. It is closely related to many other areas of mathematics and has many applications ranging from logic to statistical physics and from evolutionary biology to computer science. Combinatorics is well known for the breadth of the problems it tackles. Combinatorial problems arise in many areas of pure mathematics, notably in algebra, probability theory, topology, and geometry, as well as in its many application areas. Many combinatorial questions have historically been considered in isolation, giving an ''ad hoc'' solution to a problem arising in some mathematical context. In the later twentieth century, however, powerful and general theoretical methods were developed, making combinatorics into an independent branch of mathematics in its own right. One of the oldest and most accessible parts of combinatorics i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Argument From Motion
A cosmological argument, in natural theology, is an argument which claims that the existence of God can be inferred from facts concerning causation, explanation, change, motion, contingency, dependency, or finitude with respect to the universe or some totality of objects. A cosmological argument can also sometimes be referred to as an argument from universal causation, an argument from first cause, the causal argument, or prime mover argument. Whichever term is employed, there are two basic variants of the argument, each with subtle yet important distinctions: ''in esse'' (essentiality), and ''in fieri'' (becoming). The basic premises of all of these arguments involve the concept of causation. The conclusion of these arguments is that there exists a first cause (for whichever group of things it is being argued has a cause), subsequently deemed to be God. The history of this argument goes back to Aristotle or earlier, was developed in Neoplatonism and early Christianity and late ...

Proof Of The Existence Of God
The existence of God (or more generally, the existence of deities) is a subject of debate in theology, philosophy of religion and popular culture. A wide variety of arguments for and against the existence of God or deities can be categorized as logical, empirical, metaphysical, subjective or scientific. In philosophical terms, the question of the existence of God or deities involves the disciplines of epistemology (the nature and scope of knowledge) and ontology (study of the nature of being, existence, or reality) and the theory of value (since some definitions of God include "perfection"). The Western tradition of philosophical discussion of the existence of God or deities began with Plato and Aristotle, who made arguments that would now be categorized as cosmological. Other arguments for the existence of God or deities have been proposed by St. Anselm, who formulated the first ontological argument; Ibn Rushd (Averroes) and Thomas Aquinas, who presented ...

Characteristica Universalis
The Latin term ''characteristica universalis'', commonly interpreted as ''universal characteristic'', or ''universal character'' in English, is a universal and formal language imagined by Gottfried Leibniz able to express mathematical, scientific, and metaphysical concepts. Leibniz thus hoped to create a language usable within the framework of a universal logical calculation or '' calculus ratiocinator''. The ''characteristica universalis'' is a recurring concept in the writings of Leibniz. When writing in French, he sometimes employed the phrase ''spécieuse générale'' to the same effect. The concept is sometimes paired with his notion of a ''calculus ratiocinator'' and with his plans for an encyclopaedia as a compendium of all human knowledge. A universal pictographic language: the key to all the sciences International communication Many Leibniz scholars writing in English seem to agree that he intended his ''characteristica universalis'' or "universal character" to be a ...

Thomas Hobbes
Thomas Hobbes ( ; 5/15 April 1588 – 4/14 December 1679) was an English philosopher, considered to be one of the founders of modern political philosophy. Hobbes is best known for his 1651 book '' Leviathan'', in which he expounds an influential formulation of social contract theory. In addition to political philosophy, Hobbes contributed to a diverse array of other fields, including history, jurisprudence, geometry, theology, and ethics, as well as philosophy in general. Biography Early life Thomas Hobbes was born on 5 April 1588 (Old Style), in Westport, now part of Malmesbury in Wiltshire, England. Having been born prematurely when his mother heard of the coming invasion of the Spanish Armada, Hobbes later reported that "my mother gave birth to twins: myself and fear." Hobbes had a brother, Edmund, about two years older, as well as a sister named Anne. Although Thomas Hobbes's childhood is unknown to a large extent, as is his mother's name, it is known that Ho ...
