Taught by Professor of Philosophy James D. Reid, of the Metropolitan State University of Denver, this course traces the revolution in ideas that marked the transition from the medieval worldview to modern rationalist thought, which forms the foundation of science, law, and ethics.

02: René Descartes’s Quest for Certainty
A pioneer of early modern philosophy, René Descartes set the goal of building a foundation for knowledge that is absolutely certain. Trace the chain of reasoning in his Meditations on First Philosophy that led him to the self-evident truth of his own thinking existence. From this foundation, he demonstrates the existence of God. Look at other conclusions reached by Descartes in this remarkably subtle work.

03: Descartes’s Method and Motives
Why was Descartes so obsessed with certainty? Delve into The Discourse on the Method, which includes an intellectual autobiography. A key step was the time he spent alone in a stove-heated room, when he concluded that a single individual using reason can get closer to the truth than the aggregate of learning contained in all books. Follow the revolutionary deductions he reached by applying this method.

04: Elisabeth of Bohemia and Cartesian Ethics
In his Discourse, Descartes outlines a provisional moral code, but the full development of his ethical system emerges through his correspondence with Princess Elisabeth of Bohemia. A gifted philosopher, she posed challenging questions that prompted him to rigorously refine his ideas. Their colloquy explored happiness, virtue, emotions, and the passions, with a strong emphasis on practical ethics.

05: Lady Anne Conway’s Vitalist Metaphysics
Descartes’s works prompted Lady Anne Conway, a reclusive English noblewoman and philosopher, to set down her own ideas, which bridged metaphysics, ethics, and theology in sharp contrast to Descartes’s system. Drawing on her posthumously published treatise, Dr. Reid summarizes her influential critique of Cartesian dualism and her vitalist conception of all reality, which incorporates reincarnation.

06: Baruch Spinoza on God and Nature
While Descartes argued that mind and body are two distinct substances, Baruch Spinoza, proposed that there is only one substance, which he identified as God or Nature. Everything else, including mind and body, are modes or expressions of this one substance. Spinoza’s God is not a personal deity but an infinite, impersonal substance that encompasses all of reality.

07: Spinoza on Mind and Emotion
Continue your study of Spinoza’s Ethics by focusing on his philosophy of mind, notably his theory of emotions. Spinoza held that despite their fluid nature, emotions are far from random or irrational. Instead, they are part of the natural order, arising from encounters with external objects or events that affect the body, which in turn affects the mind. This was a highly innovative view at the time.

08: Spinoza on Bondage and Freedom
Spinoza’s theory of emotions leads to his account of bondage and freedom. Bondage relates to actions over which we have no control, while freedom is detachment from those emotions that hold us captive. These represent two opposing ways of living—one that results in frustration and suffering, and another that brings fulfillment and peace. The latter is the fundamental goal of his Ethics.

09: Nicolas Malebranche’s Occasionalism
After reading Descartes, priest and philosopher Nicolas Malebranche broke with the medieval Scholastic view, which was inspired by Aristotle, and developed his own doctrine of occasionalism. This integrated Cartesian metaphysics with a vision of divine intervention. Although rooted in a theistic framework, Malebranche’s ideas influenced later, more secular thinkers such as Hume and Kant.

10: Gottfried Wilhelm Leibniz on Truth and Being
A co-inventor of calculus with Isaac Newton, Gottfried Wilhelm Leibniz is best known as a philosopher who built a unified explanation of reality. He called his explanatory agents monads—indivisible, non-physical entities that account for being, perception, consciousness, and other natural phenomena, and play a key role in Leibniz’s understanding of truth. Explore this powerful and subtle system.

11: Leibniz on Morality and the Problem of Evil
In his satire Candide, Voltaire makes fun of Leibniz’s idea that God has created “the best of all possible worlds.” What led Leibniz to this conclusion, and how does he account for the obvious shortcomings of the universe, notably evil? Examine his distinction between metaphysical, physical, and moral forms of evil. And consider his views on freedom, moral choice, and the aspiration to perfection.

12: Rationalism Then and Now
In this last lecture, Professor Reid asks how the thinkers presented in the course shed light on today’s debates. Although early modern philosophers often disagree, they are committed to reason as the only hope for a more truthful way of inhabiting the world. Being philosophers, they accept that on matters of fundamental philosophical importance, reasonable people should be free to disagree.
