Bertrand Russell, a founding member of analytical philosophy, was born in the United Kingdom in 1872. Intelligent and versatile, Russell earned a career most notably as a philosopher, logician, political activist, and mathematician until his death in 1970. Influenced heavily by Gottfried Leibniz, Russell was conversant with and involved in every aspect of philosophy. Russell went on to influence the evolution of analytical philosophy along with philosophers Gottlob Frege and George Edward Moore. One of Russell’s most famous essays, “The Theory of Knowledge” analyzes knowledge through three discussions: the definition of knowledge, data, and methods of interference. Both Russell’s approach to and theories regarding metaphysics and epistemology*…show more content…*

The theory of types created a logical foundation for mathematics as presented by Russell in his 1908 paper Mathematical Logic as Based on the Theory of Types. Russell wrote his type theory in response to ambiguities he found in set theory. “Naive Set Theory”, as we now call it, defined sets vaguely and paradoxically allowed any variable to become a set without restriction. This confusion led Russell to publish his paradox explaining that no set consists of "all sets that do not contain themselves". Russell developed his type theory to be more precise than naive set theory. In Russell’s theory of types, each "term" has a "type" and operations are restricted to terms of a specific type. In Principia Mathematica, published in 1910, Russell and Whitehead attempt to avoid Russell’s paradox by asserting a hierarchy of types, after which each entity (mathematical or other) is assigned a type. In this way, Russell created his ramified theory of types compounded with an axiom of reducibility. As his work progressed Russell relied on the axiom of reducibility, a hierarchy of predicates, as an answer to the impredicative definitions that arose when he first introduced his ramified theory. Arguably, Russell and Whitehead’s analytical work in Principia Mathematica led to a redefinition of how logic is perceived*…show more content…*

The work garnerd new philosophical concepts such as the theory of types, logical construction, and propositional function. Significantly, Russell and Whitehead first defined a series as a set of terms with connected, asymmetrical, transitive properties. The analytical work presented in Principia Mathematica led T.S Eliot to claim, “The Principia Mathematica are perhaps a greater contribution to our language than they are to mathematics.” Regardless of some critical response, it is apparent that many contributions were made in Russell and Whitehead’s collaborative work that remain even in this century of

## Leibniz's Theory Of Morality

1585 Words | 7 PagesChristian was a man with a very wide range of interests. At the University of Halle he lectured in mathematics, physics and all aspects of philosophy. He was an extreme rationalist, basing his teaching on the work of Leibniz and emphasising the doctrine of pre - established harmony, but for the content of his rationalism, he appealed to experience. He divided the sciences into the theoretical and the practical. For many fields Wolf wrote textbooks, which were widely used in the universities.

## Rene Descartes: The Mind-Body Problem Of The Philosophy Of Mind

992 Words | 4 PagesDescartes’s works has led to the emergence of rationalism approach. His works influenced many philosophers, primarily Spinoza and Leibniz. Descartes ' s ideas are still spoken many times in our day, including ‘’I think therefore I am(cogito ergo sum)’’. For these reasons, he is considered the father of modern philosophy. In addition, Descartes also made studies about physics and the law of the nature and these studies were the source of information for the famous physicist Isaac Newton.

## Blaise Pascal Contribution To Religion

As an important side note, it is significant to mention the distinction that Pascal makes with regards to the two Gods. Before this intense vision, one could find him believing in the God of mathematical infiniteness and wisdom, much as the scholars would. Nevertheless, he finds that he had been visited by the same God as Abraham, Isaac and Jacob had. As such, this was not the result of reflection and reason, but of a vivid experience.

## Film Analysis: The Prisoner's Dilemma

927 Words | 4 PagesWhile also represented and studied in economics or philosophy, game theory takes a specific mathematical aspect. John von Neumann and Oskar Morgenstern are the first to develop it in 1944, in “The Theory of Games and Economic Behavior” because classical mathematics (often used to describe Physics for instance) revealed being inefficient to describe and explain Economics. To them, it was closer to a strategic game. Therefore, Game theory is a relatively recent branch of mathematics that studies situations in which players (sometimes called parties) make independent decisions and considering the other one possible choice while building their strategy. The decisions of the players that lead to an optimal outcome represent a solution to the game.

## Empiricism According To Lawhead's Epistemological Theory

1397 Words | 6 PagesLawhead uses the example of mathematics and logic to describe that we come to conclusions by means of reason.(192). Rationalist answer the third question of epistemology by claiming that beliefs that are based on reason are inline with reality. While Plato set up many of the beginning ideas of rationalism, it was Renee Desecrettes who gave birth to modern philosophy in the 17th century. (Lawhead, 200). Desecrettes is important because he made a rationalist connection in how we have ideas of perfection.

## Spinoza's Argument

2161 Words | 9 PagesThe Cartesian axiom declares that there is as much formal reality in the cause of an idea as the objective reality of the idea itself. Spinoza debunks the idea with his axioms of powers: “The power of Thought to think about or to comprehend things, is not greater than the power of Nature to exist and to act.” Spinoza’s emphasis on power in the Short Treatise and the Correction of the Understanding has proven a thorough argument. He expounds his thought in an array of syllogisms, they can be encapsulated in the following: The more reality something has, the more existence it involves. The possible existence Descartes proposes has finite degrees of perfection while necessary existence has infinite perfection. Whatever has the power

## Critical Thinking Definition

1012 Words | 5 PagesCritical Thinking Since critical thinking is a complicated concept, there are different definitions concerning its various aspects. The first definition may be that given by Dewey (1909, as cited in Fahim & Pezeshki, 2012), father of the new tradition in critical thinking, who first called this notion “reflective thinking” and defined it precisely as an “active, persistent, careful consideration of a belief or supposed form of knowledge in the lights of grounds which support it and the further conclusions to which it tends” (p. 154). Alternatively, Glaser (1942) a psychologist, defines critical thinking as an attitude and rational use of skills in problem-solving contexts. Siegel (1988, as cited in Liaw, 2007, p.50) calls critical thinking

## Isaac Newton Influence

1513 Words | 7 PagesInfluence of Isaac Newton in the Development of Economic Thought What makes academia so beautiful is the similar strand of thought that run through different disciplines creating familiar and similar foundation of their development. The juxtaposition of Newton with economic thought may be seen with an element of surprise and curiosity. Newton, as we all know, made large and mighty contributions to the field of science but what we may not know is how he played a crucial role in influencing thinkers of different fields to follow the similar direction of thought. Isaac Newton was a physicist, mathematician, and one of the first scientific intellects of his time in England. He was born at Woolsthorpe, near Lincolnshire in 1616.

## Dugald Stewart's Absolute Mind

1237 Words | 5 PagesDugald Stewart (1753-1828) [Edinburgh]. He taught mathematics at the University of Edinburgh, standing in for his father, until 1785, when he was appointed professor of moral philosophy. In 1792, his Elements of the Philosophy of the Human Mind appeared, and his Outlines of Moral Philosophy was published in 1793. His philosophy followed that of Reid and represented a reaction against that of Berkley and Hume. He professed to follow the method of Francis Bacon but held that it was possible to establish fundamental laws of certainty and principles of knowledge.

## The Age Of Reason Of The 17th Century And The Age Of Enlightenment

1906 Words | 8 PagesThis revolution in philosophical thought was sparked by the French philosopher and mathematician René Descartes, the first figure in the movement known as Rationalism, and much of subsequent Western philosophy can be seen as a response or a reaction to his ideas. His method was to get rid of everything about which there could be even a suspicion of doubt to arrive at the single unquestionable principle that he possessed consciousness and was able to think "I think, therefore I am" in Latin "Cogito ergo sum" When François Marie Arouet de Voltaire (1694–1778) was visiting London, he found that philosophy like many other things there had changed significantly. He had left the world a plenum, and now he now found it was a vacuum. At Paris the universe was seen composed of vortices of subtle matter but nothing
