From the author of the #1 New York Times bestseller On Bullshit, a landmark account of Descartes, reason, and truth In this classic work, philosopher and bestselling author Harry Frankfurt provides a compelling analysis of the question that not only lies at the heart of Descartes's Meditations, but also constitutes the central preoccupation of modern philosophy: on what basis can reason claim to provide any justification for the truth of our beliefs? Demons, Dreamers, and Madmen provides an ingenious account of Descartes's defense of reason against his own famously skeptical doubts that he might be a madman, dreaming, or, worse yet, deceived by an evil demon into believing falsely. Frankfurt's masterful and imaginative reading of Descartes's seminal work not only stands the test of time; one imagines Descartes himself nodding in agreement.

#1 New York Times bestseller Featured on The Daily Show and 60 Minutes The acclaimed book that illuminates our world and its politics by revealing why bullshit is more dangerous than lying One of the most prominent features of our world is that there is so much bullshit. Yet we have no clear understanding of what bullshit is, how it’s distinct from lying, what functions it serves, and what it means. In his acclaimed bestseller On Bullshit, Harry Frankfurt, who was one of the world’s most influential moral philosophers, explores this important subject, which has become a central problem of politics and our world. With his characteristic combination of philosophical acuity, psychological insight, and wry humor, Frankfurt argues that bullshitters misrepresent themselves to their audience not as liars do, that is, by deliberately making false claims about what is true. Rather, bullshitters seek to convey a certain impression of themselves without being concerned about whether anything at all is true. They quietly change the rules governing their end of the conversation so that claims about truth and falsity are irrelevant. Although bullshit can take many innocent forms, excessive indulgence in it can eventually undermine the bullshitter’s capacity to tell the truth in a way that lying does not. Liars at least acknowledge that the truth matters. Because of this, bullshit is a greater enemy of the truth than lies are. Remarkably prescient and insightful, On Bullshit is a small book that explains a great deal about our time.

From the author of the #1 New York Times bestseller On Bullshit, a profound meditation on how and why we love In The Reasons of Love, leading moral philosopher and bestselling author Harry Frankfurt argues that the key to a fulfilled life is to pursue wholeheartedly what one cares about, that love is the most authoritative form of caring, and that the purest form of love is, in a complicated way, self-love. Through caring, we infuse the world with meaning. Caring provides us with stable ambitions and concerns, and it shapes the framework of aims and interests within which we lead our lives. Love is a nonvoluntary, disinterested concern for the flourishing of what we love—and self-love, as distinct from self-indulgence, is at heart of this concern. The most elementary form of self-love is no more than the desire to love, and self-love is simply a commitment to finding meaning in our lives.

From the author of the #1 New York Times bestseller On Bullshit, the case for worrying less about the rich and more about the poor Economic inequality is one of the most divisive issues of our time. Yet few would argue that inequality is a greater evil than poverty. The poor suffer because they don't have enough, not because others have more, and some have far too much. So why do many people appear to be more distressed by the rich than by the poor? In this provocative book, the #1 New York Times bestselling author of On Bullshit presents a compelling and unsettling response to those who believe that the goal of social justice should be economic equality or less inequality. Harry Frankfurt, one of the most influential moral philosophers in the world, argues that we are morally obligated to eliminate poverty—not achieve equality or reduce inequality. Our focus should be on making sure everyone has a sufficient amount to live a decent life. To focus instead on inequality is distracting and alienating. At the same time, Frankfurt argues that the conjunction of vast wealth and poverty is offensive. If we dedicate ourselves to making sure everyone has enough, we may reduce inequality as a side effect. But it’s essential to see that the ultimate goal of justice is to end poverty, not inequality. A serious challenge to cherished beliefs on both the political left and right, On Inequality promises to have a profound impact on one of the great debates of our time.

First published in 1961, Perception and the Physical World contends that there are insuperable difficulties for the Representative and Phenomenalist theories. Unreflective common sense thinks of sense-perception as a direct grasping of the nature of the physical world. But when we are confronted with facts about sensory illusion, about the physical and physiological causes of perception, and with modern scientific views of the real nature of matter, it is hard to maintain such a ‘Direct Realist’ theory of perception. We tend to substitute a Copy or Representative theory which puts sense-impressions between ourselves and physical reality. Some philosophers overwhelmed by the difficulties of the Copy theory, retreat into Phenomenalism, which identifies the physical world with our sense-impressions. The author re-examines all the traditional objections to a Direct Realist theory and tries to show that they can be overcome. This book will be of interest to students of philosophy.
