The Unconscious of Thought in Leibniz, Spinoza, and Hume

Three early modern philosophers - Spinoza, Leibniz and Hume - understood that minds necessarily involve ideas and patterns of thinking that are not conscious. Morejon shows that in this way they sharply distinguish themselves from other major early modern thinkers whose conceptions of the mind tended to identify thinking with consciousness, such as Descartes, Malebranche and Locke. This conception of the thinking mind as conscious remains popular even today.By contrast, Leibniz, Spinoza and Hume argue instead that thought is not, as such, a matter of consciousness. Morejon explores the significance of this insight for their conceptions of freedom and ethics. By systematically analyzing the major writings of these three thinkers and placing them in the context of the history of Western philosophy, he shows that together they provide us with a metaphysics of ideas that is uniquely helpful for thinking through important problems in contemporary political theory.In particular, it allows us to understand how it is possible for people to act against their own interests and in spite of their consciously knowing better. Readers will gain a sophisticated understanding of what Leibniz, Spinoza and Hume thought about the metaphysics of ideas, the nature of the human mind and the limits of individual freedom.
