Here in one convenient volume are Volumes IV, V, and VI - complete and unabridged - of the acclaimed reference work that has dominated the field of phlosophy for two decades. Volume IV discusses the philosophies of Descartes, Pascal, Malebranche, Spinoza, and Leibniz. Volume V covers British philosophy during the seventeenth and eighteenth centuries, marked by such giants as Hobbes, Locke, Berkeley, and Hume, as well as other movements of far-reaching significance. Copleston takes up the eighteenth-century continental philosophers in Volume VI - beginning with the French Enlightenment (including Fontenelle, Helvétius, Robinet, Rousseau) and then going to the German Enlightenment (which includes the work of Lessing and Wolff) and finally to an intense treatment of Immanuel Kant.
