A new, scholarly and accessible translation of this seventeenth-century philosophical text, including an introduction, glossary and chronology.

Baruch Spinoza’s Ethics is a dense masterpiece of sustained argumentative reasoning. It earned its place as one of the most important and influential books in Western philosophy by virtue of its uncompromisingly direct arguments about the nature of God, the universe, free will, and human morals. Though it remains one of the densest and most challenging texts in the entire canon of Western philosophy, Ethics is also famous for Spinoza’s unique approach to ordering and constructing its arguments. As its full title – Ethics, Demonstrated in Geometrical Order – suggests, Spinoza decided to use the rigorous format of mathematical-style propositions to lay out his arguments, just as the Ancient Greek mathematician Euclid had used geometrical propositions to lay out the basic rules of geometry. In choosing such a systematic method, Spinoza’s masterwork shows the crucial aspects of good reasoning skills being employed at the highest level. The key use of reasoning is the production of an argument that is well-organised, supports its conclusions and proceeds logically towards its end. Just as a mathematician might demonstrate a geometrical proof, Spinoza sought to lay out a comprehensive philosophy for human existence – an attempt that has influenced generations of philosophers since.

Ethics, Demonstrated in Geometrical Order (Latin: Ethica, ordine geometrico demonstrata), usually known as the Ethics, is a philosophical treatise written by Benedict de Spinoza. It was written between 1664 and 1665 and was first published in 1677.The book is perhaps the most ambitious attempt to apply the method of Euclid in philosophy. Spinoza puts forward a small number of definitions and axioms from which he attempts to derive hundreds of propositions and corollaries, such as "When the Mind imagines its own lack of power, it is saddened by it", "A free man thinks of nothing less than of death", and "The human Mind cannot be absolutely destroyed with the Body, but something of it remains which is eternal."

Ethics - Part 3, is many of the old books which have been considered important throughout the human history. They are now extremely scarce and very expensive antique. So that this work is never forgotten we republish these books in high quality, using the original text and artwork so that they can be preserved for the present and future generations. This whole book has been reformatted, retyped and designed. These books are not made of scanned copies of their original work and hence the text is clear and readable.

This work examines the unique way in which Benedict de Spinoza (1632–77) combines two significant philosophical principles: that real existence requires causal power and that geometrical objects display exceptionally clearly how things have properties in virtue of their essences. Valtteri Viljanen argues that underlying Spinoza's psychology and ethics is a compelling metaphysical theory according to which each and every genuine thing is an entity of power endowed with an internal structure akin to that of geometrical objects. This allows Spinoza to offer a theory of existence and of action - human and non-human alike - as dynamic striving that takes place with the same kind of necessity and intelligibility that pertain to geometry. Viljanen's fresh and original study will interest a wide range of readers in Spinoza studies and early modern philosophy more generally.

Autonomous cars, drones, and electronic surveillance systems are examples of technologies that raise serious ethical issues. In this analytic investigation, Martin Peterson articulates and defends five moral principles for addressing ethical issues related to new and existing technologies: the cost-benefit principle, the precautionary principle, the sustainability principle, the autonomy principle, and the fairness principle. It is primarily the method developed by Peterson for articulating and analyzing the five principles that is novel. He argues that geometric concepts such as points, lines, and planes can be put to work for clarifying the structure and scope of these and other moral principles. This geometric account is based on the Aristotelian dictum that like cases should be treated alike, meaning that the degree of similarity between different cases can be represented as a distance in moral space. The more similar a pair of cases are from a moral point of view, the closer is their location in moral space. A case that lies closer in moral space to a paradigm case for some principle p than to any paradigm for any other principle should be analyzed by applying principle p. The book also presents empirical results from a series of experimental studies in which experts (philosophers) and laypeople (engineering students) have been asked to apply the geometric method to fifteen real-world cases. The empirical findings indicate that experts and laypeople do in fact apply geometrically construed moral principles in roughly, but not exactly, the manner advocates of the geometric method believe they ought to be applied.

Spinoza's Ethics, published in 1677, is considered his greatest work and one of history's most influential philosophical treatises. This volume brings established scholars together with new voices to engage with the complex system of philosophy proposed by Spinoza in his masterpiece. Topics including identity, thought, free will, metaphysics, and reason are all addressed, as individual chapters investigate the key themes of the Ethics and combine to offer readers a fresh and thought-provoking view of the work as a whole. Written in a clear and accessible style, the volume sets out cutting-edge research that reflects, challenges, and promotes the most recent scholarly advances in the field of Spinoza studies, tackling old issues and bringing to light new subjects for debate.
