Introduction Sally Shuttleworth and Geoffrey Cantor
1 Introduction Sally Shuttleworth and Geoffrey Cantor “Reviews are a substitute for all other kinds of reading—a new and royal road to knowledge,” trumpeted Josiah Conder in 1811.1 Conder, who sub- sequently became proprietor and editor of the Eclectic Review, recognized that periodicals were proliferating, rapidly increasing in popularity, and becoming a major sector in the market for print. Although this process had barely begun at the time Conder was writing, the number of peri- odical publications accelerated considerably over the ensuing decades. According to John North, who is currently cataloguing the wonderfully rich variety of British newspapers and periodicals, some 125,000 titles were published in the nineteenth century.2 Many were short-lived, but others, including the Edinburgh Review (1802–1929) and Punch (1841 on), possess long and honorable histories. Not only did titles proliferate, but, as publishers, editors, and proprietors realized, the often-buoyant market for periodicals could be highly profitable and open to entrepreneurial exploitation. A new title might tap—or create—a previously unexploited niche in the market. Although the expensive quarterly reviews, such as the Edinburgh Review and the Quarterly, have attracted much scholarly attention, their circulation figures were small (they generally sold only a few thousand copies), and their readership was predominantly upper middle class. By contrast, the tupenny weekly Mirror of Literature is claimed to have achieved an unprecedented circulation of 150,000 when it was launched in 1822. A few later titles that were likewise cheap and aimed at a mass readership also achieved circulation figures of this magnitude. -
Carl Gustav Jacob Jacobi
CARL GUSTAV JACOB JACOBI Along with Norwegian Niels Abel, German mathematician Carl Gustav Jacob Jacobi (December 10, 1804 – February 18, 1851) was one of the founders of the theory of elliptic functions, which he described in his 1829 work Fundamenta Nova Theoriae Functionum Ellipticarum (New Foundations of the Theory of Elliptic Functions). His achievements in this area drew praise from Joseph-Louis Lagrange, who had spent some 40 years studying elliptic integrals. Jacobi also investigated number theory, mathematical analysis, geometry and differential equations. His work with determinants, in particular the Hamilton-Jacobi theory, a technique of solving a system of partial differential equations by transforming coordinates, is important in the presentation of dynamics and quantum mechanics. V.I. Arnold wrote of the Hamilton-Jacobi method, “… this is the most powerful method known for exact integration.” Born in Potsdam, Jacobi was the son of a prosperous Jewish banker. His older brother Moritz Hermann Jacobi was a well-known physicist and engineer. The latter worked as a leading researcher at the Academy of Sciences in St. Petersburg. During their lifetimes Moritz was the better known of the two for his work on the practical applications of electricity and especially for his discovery in 1838 of galvanoplastics. Also called electrotyping, it is a process something like electroplating for making duplicate plates of relief, or letterpress, printing. Carl was constantly mistaken for his brother or even worse congratulated for having such a distinguished and accomplished brother. To one such compliment he responded with annoyance, “I am not his brother, he is mine.” Carl Jacobi demonstrated great talent for both languages and mathematics from an early age. -

Hamiltonian System and Dissipative System
Hamiltonian system and Dissipative system: Motivating example: (energy and DE) y00 + qy = 0 system: y0 = v, v0 = −qy y00 + py0 + qy = 0 system: y0 = v, v0 = −qy − pv 1 1 Energy function: E(y, v) = v2 + qy2 2 2 1 where v2 is the kinetic energy (note that m = 1) 2 1 and qy2 is the potential energy (example: q = g) 2 1 y00 + qy = 0 d d 1 1 E(y(t), v(t)) = v2(t) + qy2(t) = v(t)v0(t) + qy(t)y0(t) dt dt 2 2 = v(t)(−qy(t)) + qy(t) · v(t) = 0 (energy is conserved) y00 + py0 + qy = 0 d d 1 1 E(y(t), v(t)) = v2(t) + qy2(t) = v(t)v0(t) + qy(t)y0(t) dt dt 2 2 = v(t)(−qy(t) − pv(t)) + qy(t) · v(t) = −p[v(t)]2 ≤ 0 (energy is dissipated) 2 Definition: dx dy = f(x, y), = g(x, y). dt dt If there is a function H(x, y) such that for each solution orbit d (x(t), y(t)), we have H(x(t), y(t)) = 0, then the system is a dt Hamiltonian system, and H(x, y) is called conserved quantity. (or energy function, Hamiltonian) If there is a function H(x, y) such that for each solution orbit d (x(t), y(t)), we have H(x(t), y(t)) ≤ 0, then the system is a dt dissipative system, and H(x, y) is called Lyapunov function. (or energy function) 3 Example: If a satellite is circling around the earth, it is a Hamil- tonian system; but if it drops to the earth, it is a dissipative system. -
The Philosophy of Religion Contents
The Philosophy of Religion Course notes by Richard Baron This document is available at www.rbphilo.com/coursenotes Contents Page Introduction to the philosophy of religion 2 Can we show that God exists? 3 Can we show that God does not exist? 6 If there is a God, why do bad things happen to good people? 8 Should we approach religious claims like other factual claims? 10 Is being religious a matter of believing certain factual claims? 13 Is religion a good basis for ethics? 14 1 Introduction to the philosophy of religion Why study the philosophy of religion? If you are religious: to deepen your understanding of your religion; to help you to apply your religion to real-life problems. Whether or not you are religious: to understand important strands in our cultural history; to understand one of the foundations of modern ethical debate; to see the origins of types of philosophical argument that get used elsewhere. The scope of the subject We shall focus on the philosophy of religions like Christianity, Islam and Judaism. Other religions can be quite different in nature, and can raise different questions. The questions in the contents list indicate the scope of the subject. Reading You do not need to do extra reading, but if you would like to do so, you could try either one of these two books: Brian Davies, An Introduction to the Philosophy of Religion. Oxford University Press, third edition, 2003. Chad Meister, Introducing Philosophy of Religion. Routledge, 2009. 2 Can we show that God exists? What sorts of demonstration are there? Proofs in the strict sense: logical and mathematical proof Demonstrations based on external evidence Demonstrations based on inner experience How strong are these different sorts of demonstration? Which ones could other people reject, and on what grounds? What sort of thing could have its existence shown in each of these ways? What might we want to show? That God exists That it is reasonable to believe that God exists The ontological argument Greek onta, things that exist. -
Introduction Setting the Scene
Introduction Setting the Scene On 7 April, 1875, mathematics students turning up for their morning lecture at University College London were surprised to see a message chalked on the blackboard. It read, ‘I am obliged to be absent on important business which will probably not occur again.’ The Professor of Applied Mathematics and Mechanics, William Kingdon Clifford, was getting married on that day. He had come to London from Trinity College, Cambridge, in 1871 and was twenty-nine years old. He was highly intellectual, tremendously popular, slightly eccentric and such a brilliant lecturer that he had taken the academic world by storm. His bride to be was Sophia Lucy Jane Lane. She was one year younger than William Clifford and had already begun to establish herself as a novelist and journalist. He and Lucy made a most attractive and lively couple and they drew around them a wide circle of friends from all walks of life. In 1874, when their engagement had been announced, William Clifford received this letter: Few things have given us more pleasure than the intimation in your note that you had a fiancée. May she be the central happiness and motive force of your career, and by satisfying the affections, leave your rare intellect free to work out its glorious destiny. For, if you don’t become a glory to your age and time, it will be a sin and a shame. Nature doesn’t often send forth such gifted sons, and when she does, Society usually cripples them. Nothing but marriage – a happy marriage – has seemed to Mrs Lewes and myself wanting to your future.1 The letter was from his close friend, the publisher, writer, and philosopher George Henry Lewes.SAMPLE Mrs Lewes was, of course, George Eliot. -

Dewey and Rorty on Kant
WHY NOT ALLIES RATHER THAN ENEMIES? DEWEY AND RORTY ON KANT István Danka E-mail: [email protected] In my paper I shall investigate Rorty's claim how Kant's philosophy is a reductio ad absurdum of the traditional object-subject distinction. I shall argue that most of the common arguments against Rorty's philosophy are based on the same mistake as some of the common arguments against Kant (shared by Dewey and Rorty as well). Though their philosophies differ in several aspects with no doubt, in their anti-skeptical and hence Anti-Cartesian strategy, central to all three of them, they follow the same sort of argumentation. First I shall make some methodological remarks, distinguishing my sort of critique from traditional Anti-Rortyan strategies. Then I shall identify the two main distinctive features between Dewey and Rorty as the latter's return to certain idealist issues. Third, I shall investigate three Kantian topics in pragmatism: the denial of the subject-object dualism, constructivism, and transcendental argumentation. Finally, I shall focus on the question how transcendental idealism could help a Rortyan in order to avoid the same critique as by which Rorty, following Dewey, attacked Kantians. 1. Methodological remarks 1.1. How not to argue against Rorty Richard Rorty is one of the most criticised contemporary philosophers. In order to avoid a misleading reading of my paper, according to which my purpose would be similar to the most common critiques of him, I must say a word or two why my present line of thought is a radically Rortyan one. -
