"Principles of Philosophy is an attempt, by a self-taught genius, to persuade the Yiddish speaking public that philosophy has not lost its central importance vis a vis both religion and science. He does this, first, by identifying religion with philosophy - and he is the first Orthodox rabbi since Maimonides to do so. Next, he argues that philosophical principles, which are broader than those of science, are at the basis of all existence, and that the same principles that account for the organization of matter can account for the varieties of human organization (and disorganization). He argues, finally, that the study of philosophy itself can lead to the weakening of egotism and the strengthening of altruism."--BOOK JACKET.

Preface gives a synopsis of Spinoza, his life, and where he was at during this time period. The book gives a huge depth into Cartesian Philosophy which is the philosophical doctrine of Rene Descartes. It also speaks of metaphysics in relation to Spinoza and Cartesian Philosophy. Baruch or Benedict de Spinoza was a Dutch philosopher of Portuguese Jewish origin. Revealing considerable scientific aptitude, the breadth and importance of Spinoza's work was not fully realized until years after his death. Today, he is considered one of the great rationalists of 17th-century philosophy, laying the groundwork for the 18th century Enlightenment and modern biblical criticism. By virtue of his magnum opus, the posthumous Ethics, in which he opposed Descartes' mind-body dualism, Spinoza is considered to be one of Western philosophy's most important philosophers. Philosopher and historian Georg Wilhelm Friedrich Hegel said of all modern philosophers, "You are either a Spinozist or not a philosopher at all." All of Spinoza's works were listed on the Index Librorum Prohibitorum (List of Prohibited Books) by the Roman Catholic Church. Spinoza lived quietly as a lens grinder, turning down rewards and honors throughout his life, including prestigious teaching positions, and gave his family inheritance to his sister. Spinoza's moral character and philosophical accomplishments prompted 20th century philosopher Gilles Deleuze to name him "the 'prince' of philosophers." Spinoza died at the age of 44 of a lung illness, perhaps tuberculosis or silicosis exacerbated by fine glass dust inhaled while tending to his trade. Spinoza is buried in the churchyard of the Nieuwe Kerk on Spui in The Hague.

" Le Discours de la méthode (sous-titré : Pour bien conduire sa raison, et chercher la vérité dans les sciences) est un texte philosophique publié anonymement par René Descartes à Leyde le 8 juin 1637. Il devait originellement servir d'introduction générale aux traités scientifiques écrits par l'auteur (La Dioptrique, Les Météores et La Géométrie). Il s'agissait pour Descartes « d’en dire assez pour faire juger que les nouvelles opinions, qui se verraient dans la Dioptrique et dans les Météores, n’étaient point conçues à la légère. Toutefois, la célébrité du texte est devenue telle, qu’il est désormais souvent publié seul, comme un essai indépendant. Il est reconnu comme l'une des œuvres fondatrices de la philosophie occidentale."

The Principles of Philosophy By Rene Descartes The only apprehension I entertain is lest the title should deter some who have not been brought up to letters, or with whom philosophy is in bad repute, because the kind they were taught has proved unsatisfactory; and this makes me think that it will be useful to add a preface to it for the purpose of showing what the MATTER of the work is, what END I had in view in writing it, and what UTILITY may be derived from it. But although it might be my part to write a preface of this nature, seeing I ought to know those particulars better than any other person, I cannot nevertheless prevail upon myself to do anything more than merely to give a summary of the chief points that fall, as I think, to be discussed in it: and I leave it to your discretion to present to the public such part of them as you shall judge proper.

The Cambridge Descartes Lexicon is the definitive reference source on René Descartes, 'the father of modern philosophy' and arguably among the most important philosophers of all time. Examining the full range of Descartes' achievements and legacy, it includes 256 in-depth entries that explain key concepts relating to his thought. Cumulatively they uncover interpretative disputes, trace his influences, and explain how his work was received by critics and developed by followers. There are entries on topics such as certainty, cogito ergo sum, doubt, dualism, free will, God, geometry, happiness, human being, knowledge, Meditations on First Philosophy, mind, passion, physics, and virtue, which are written by the largest and most distinguished team of Cartesian scholars ever assembled for a collaborative research project - 92 contributors from ten countries.

Descartes's Principles 0. / Philosophy is his longest and most ambitious work; it is the only work in which he attempted to actually deduce scientific knowledge from Cartesian metaphysics, as he repeatedly claimed was possible. Whatever the success of this attempt, there can be no doubt that it was enormously influential. Cartesian celestial mechanics held sway for well over a century, and some of the best minds of that period, including Leibniz, Malebranche, Euler, and the Bernoullis, attempted to modify and quantify the Cartesian theory of vortices into an acceptable alternative to Newton's theory of universal gravitation. Thus, the Principles is not only of inherent and historical interest philosophically but is also a seminal document in the history of science and of 17th Century thought. Principles of Philosophy was first published in Latin, in 1644. In 1647, a French translation, done by the Abbe Claude Picot and containing a great deal of additional material and a number of alterations in the original text, was published with Descartes's enthusiastic approval. Unlike some English translations of portions of the Principles, this translation uses the Latin text as its primary source; however, a good deal of additional material from Picot's translation has been included. There are several reasons for this. First, there is good evidence that Descartes himself was responsible for some of the additional material, including, of course, the Preface to the French translation.
