THE SECRET CODES OF THE MIND: FROM MEDIEVAL PHILOSOPHY TO THE ENLIGHTENMENT, PART TWO (Paperback)

What happens when reason turns away from inherited systems—and demands a new foundation for knowledge?

Across the seventeenth and eighteenth centuries, philosophers pressed a new set of questions to the limit: what can the mind know with certainty, what comes from experience, and what kind of political and moral order follows from human nature? From Medieval Philosophy to the Enlightenment, Volume IV, Part Two traces these arguments through four decisive currents of early modern thought.

Lecture 23. René Descartes: From Doubt to Truth, a Lifelong Journey.

Descartes begins by doubting everything that can be doubted. The cogito, clear and distinct ideas, the existence of God, and the division between mind and body become elements in an attempt to rebuild knowledge from a secure foundation. Can the thinking self establish the reality of a world beyond thought?

Lecture 24. Empiricism: From Experiment to Experience (Bacon, Hobbes, and Locke).

Bacon exposes the “idols” that distort judgment and redirects inquiry toward observation and experiment. Hobbes builds a materialist account of human nature, conflict, sovereignty, and the social contract. Locke grounds knowledge in experience and connects personal identity, natural rights, property, and government to the freedom and responsibility of the individual.

Lecture 25. Rationalism: The Mathematics of the Mind and the Faith of the Heart (Leibniz and Blaise Pascal).

Leibniz seeks the rational order of creation through monads, sufficient reason, pre-established harmony, and the problem of evil. Pascal confronts the fragility of human beings, the limits of demonstration, the claims of faith, and the necessity of decision under uncertainty. Leibniz extends rational explanation to creation itself; Pascal shows why questions of faith cannot be settled by proof alone.

Lecture 26. David Hume and Adam Smith: Skepticism and the Nature of Human Knowledge.

Hume submits causation, induction, the self, religion, and morality to skeptical analysis. Habit and sentiment acquire a central place in judgment. Smith extends the inquiry through sympathy and the impartial spectator, then turns toward labor, exchange, markets, and the moral conditions of social life.

Can certainty survive radical doubt? Does experience set the limits of knowledge? Can political authority be derived from human nature? Do morality and social order arise from reason, sentiment, interest, or sympathy?
