Paul Henri Thiry, Baron d'Holbach was a philosopher, translator, and prominent social figure of the French Enlightenment. In his philosophical writings Holbach developed a deterministic and materialistic metaphysics which grounded his polemics against organized religion and his utilitarian ethical and political theory. As a translator, Holbach made significant contributions to the European Enlightenment in science and religion. He translated German works on chemistry and geology into French, summarizing many of the German advances in these areas in his entries in Diderot's Encyclopedia. Holbach also translated important English works on religion and political philosophy into French. Holbach remains best known, however, for his role in Parisian society. The close circle of intellectuals that Holbach hosted and, in various ways, sponsored produced the Encyclopedia and a number of revisionary religious, ethical, and political works that contributed to the ideological basis for the French Revolution. Despite the radical views of many members of his coterie, however, Holbach's broader visiting guest list included many of the most prominent intellectual and political figures in Europe. His salon, then, was at once a shelter for radical thought and a hub of mainstream culture

Spinoza's remarks about consciousness in the Ethics constitute two theories about conscious experience and knowledge. Several remarks, including 3p9 and 4p8, make the point that self knowledge—an especially valuable good for Spinoza—is not available to introspection. We are, as a matter of course, conscious of ourselves, but we do not, as a matter of course, know ourselves. A second group of remarks, all of which occur in part 5 of the Ethics, emphasizes a different point about consciousness and knowledge: the knowledge that distinguishes the minds of the most powerful or virtuous people is conscious. The characterization of human consciousness that underlies both theories is best understood as one on which a wide variety of ideas in human minds are conscious, and the intensity or degree of consciousness of a given idea is a function of its power. For human minds, because the power of any idea derives from the power of its causes and because many ideas have external causes, there are no grounds for taking the intensity of conscious experience to track a mind's power closely. Rather, as the second group of remarks suggests, power in a human mind tracks the degree to which knowledge characterizes a mind's conscious states

It is puzzling that Spinoza both urges people to seek to preserve themselves and also holds that, as a matter of fact, people do strive to preserve themselves. I argue that the striving for self-preservation that characterizes all individuals grounds, for Spinoza, the claim that human beings seek only whatever they anticipate will lead to pleasure (laetitia). People desire ends other than self-preservation because they anticipate pleasure in those ends, and Spinoza urges people to seek to preserve themselves because he thinks such desires misguided: the anticipation of pleasure in any end that does not conduce to self-preservation is mistaken
