"e;Love is joy with the accompanying idea of an external cause."e; Spinoza's definition of love (Ethics Book 3, Prop. LIX) manifests a major paradigm shift achieved by seventeenth century Europe in which the emotions, formerly seen as normative "e;forces of nature,"e; were embraced by the new science of the mind. We are determined to volition by causes. This shift has often been seen as a transition from a philosophy laden with implicit values and assumptions to a more scientific and value-free way of understanding human action. But is this rational approach really value-free? Today we incline to believe that values are inescapable, and that the descriptive-mechanical method implies its own set of values. Yet the assertion by Spinoza, Malebranche, Leibniz, and Enlightenment thinkers that love guides us to wisdom-and even that the love of a God who creates and maintains order and harmony in the world forms the core of ethical behaviour-still resonates powerfully with us. It is, evidently, an idea we are unwilling to relinquish. This collection of insightful essays emerged from two "e;ContactFora"e; organized within the framework of the research project Actuality of the Enlightenment: The Moral Science of Emotions, conducted under the auspices of Koninklijke Vlaamse Academie van Belgie voor Wetenschappen en Kunsten. It offers a range of important and fascinating perspectives on how the triumph of "e;reason"e; affected not only our scientific-philosophical understanding of the emotions and especially of love, but our everyday understanding as well.
