The most recommended books on rationalism

Foucault’s groundbreaking work from the 1960s looks at how systems of order and classification came into being during the age of rationalism with Descartes, culminating in the 18th-century Enlightenment’s project of subjecting every field of knowledge to its own self-enclosed order. It remains of the great works of theoretical synthesis, patiently dissecting the structures of knowledge, of order and priority, that western learning continues to take for granted. At half a century’s distance, Foucault is the one French thinker whose legacy remains intact for his lucidity, polemical edge, and refusal of esoteric linguistic games.

Feyerabend argues against monism in science.

Drawing on the history of science, he demonstrates that science has progressed from pluralism. In other words, there is no the scientific method. 

Currently, mainstream economics education does not include history or philosophy in its curriculum. And economists are enthusiastically adopting a monist approach to knowledge production.

Feyerabend’s book tells us why such a naïve and narrow approach to knowledge dissemination (and production) is problematic. I feel extremely lucky to have been exposed to his work along with other philosophers of science during my master’s.

Political scientists and economists have long argued that voters are rationally ignorant.

On this theory, people tend to acquire and retain information only if the expected benefits exceed the expected costs. This explains why students cram material to pass a test but let themselves forget it afterward, why Americans who speak English at home don’t usually bother to learn a foreign language but so many people learn English, or why you don’t bother attempt to memorize your local phonebook.

It also explains why voters know so little. Since individual votes make so little difference, individual voters can afford to remain ignorant. Political information is a collective action problem: what we know matters, but what any one of us knows does not. 

Caplan adds an innovation. This point also applies to how we think, not just what we know. Political psychologists have long found that voters process what little information they… show more.

This is another important contribution to our understanding of Spinoza as a moral philosopher. It is a denser read than the first three books, but fascinating nonetheless for those already with a little Spinoza under their belt. Rather than concentrating on just the latter parts of the Ethics, where most scholars interested in Spinoza’s moral philosophy focus and where we find the mature discussion of the “free person” who lives under the “guidance of reason”, Sangiacomo is especially concerned with the evolution of Spinoza’s moral thought from his earliest writings to his final, uncompleted work. He considers tensions within, and pressures upon, Spinoza’s understanding of the “Supreme Good” and how to achieve it, and the changes that that account consequently undergoes. Sangiacomo’s thesis is thus both historical and philosophical.

I am tempted to say: Because Frank is a delightful writer and leave it at that.

This book reiterates similar themes in discussing how a variety of supposedly non-economic factors affect economic decisions.

In this book Frank discusses how noble human tendencies (moral sentiments) may have not only survived the pressures of the material world, but actually have been nurtured by them. The title is a play on the David Hume quote that “Reason is, and ought to be the slave of the passions, and can never pretend to any other office than to serve and obey them.”

To those interested, I also recommend any of Frank’s other books including Choosing the Right Pond, The Winner Take All Society, and The Darwin Economy. 

This remarkable study, first published in Czechoslovakia in 1964 and translated into English in the 1970s, is one of the most profound studies of the Hegelian and Phenomenological dimensions of Marx’s work ever written.

It argues that daily life in capitalist modernity takes the alienated form of a “world of the pseudo-concrete,” in which possibilities for self-development and purposeful creation that is integral to humanity become radically suppressed. If you want to understand why the world is not as you wish it to be, read this book.

If you’re older, you probably read O’Connor’s short story “A Good Man is Hard to Find” for one or more lit classes; if you’re younger, you may have never heard of her as she is now “problematic” according to the unfunny woke-on-steroids crowd. I love O’Connor because I love characters with moral failings, I love mordant humor, and I love the possibility that even the most irredeemable among us can experience moments of grace. The brief details in her stories do such heavy lifting in terms of irony, for example when a Wellesley undergrad hits Mrs. Turpin in the head with a copy of Human Development in the short story “Revelation.” The action itself – a privileged white college student from an elite school inflicting violence upon a rural white woman – also speaks to our ongoing culture wars. 

A long time ago, back in the mid-1970s, my Greek history professor told me that Dodds’ Greeks and the Irrational was one of the most important books on Greek history of the 20th century. He was right. It is a wonderful book, full of amazing facts about magic, ritual, and religion. It has had a huge impact on the field of classical studies and is still in print 70 years after its first publication. Dodds was a distinguished Greek scholar (the Regius Professor of Greek at Oxford) but wrote for a wide audience interested in not only Greek civilization but social science as well. I have thought hard and long about his book ever since reading it on my professor’s recommendation. 

This book first came out in 1926 but it’s interesting how much of what he teaches in this book is still relevant and lacking in today’s workplace. He is falsely remembered for his operations concepts as if they were more important than the employee, but he stresses over and over again the importance of focusing on the needs of the employee. This is also reflected in his objective of creating a vehicle for the average man, making his life easier and happier. If we would have listened and learned from him long ago we may not be rehearing these same messages again coming from Japanese automakers.

I found this work to be a complex and nuanced introduction to the much-debated and poorly understood intellectual revolution that was the Enlightenment.

Although the book lies outside my own area of academic expertise, I could easily follow its sweeping narrative as it moved through both familiar and obscure writers and thinkers. Few subjects escape its attention, and the volume is particularly strong in exploring the complex relationship between Enlightenment rationalism and Christianity. 

Following your reading of Bryson, Harari, and Greene, Hitchens approaches the science/religion dilemma from an examination of the impact of religion in general on the human race. His examination is scathing and scintillating and highly provocative. Do we trust our beliefs or evidence? Are we even willing to look at the evidence? This leads us to Kahneman. 

Arguably the greatest work of moral philosophy of the 20th Century.  It’s rich with vivid thought experiments – including Parfit’s famous tele-transporter, which can make an exact copy of us and transport us to another planet. Is this copy of me the same person as me? The book makes us question some of our deepest assumptions - such as what it means to say that David Edmonds today is identical to David Edmonds yesterday or tomorrow. Parfit was my first supervisor, and I’m now writing his biography.

Jordan’s is probably the most elegantly written of the five studies and stands out for providing a particularly generous allocation of space to Robespierre’s voice, telling the story of his life as much as possible through his own words. At the same time, Jordan’s intellectual biography is quietly attentive to providing a sense of the complex political environment in which any French revolutionary statesman had to act.

This is a self-help book with serious depth and substance. Although some of it is dated, the timeless reflections that Russell draws from the humanist tradition of which he was a part contain wisdom that can transform your life. He is strongest on the ingredients of happiness and the last chapter, on the happy person, is still a go-to for me to remind myself of what matters most. 

This book contains a magisterial rendering of the mystical poet Angelus Silesius’s verse, “The Rose Is Without Why” as part of a critical analysis of the emergence of the modern idea of “reason.”

This book has never left me since I first encountered it in my doctoral dissertation on Heidegger back in the 1960s. It landed like a bombshell on a young Catholic like me, opening a poetic and mystical sense of life free from the creeds and authoritarianism of religion as well as from the doctrinaire dismissiveness of Enlightenment rationalism.

Written at the end of his career, it encapsulates everything Heidegger was getting at. We must never forget the horrible stain of Heidegger’s National Socialism, which I have analyzed (Demythologizing Heidegger), but there is more to Heidegger than that, and you can find it here.

In this book, Horty uses tools that were originally developed in the fields of artificial intelligence and non-monotonic logic in order to develop an explanatory theory of how reasons compete with one another. The main thing that has led contemporary moral philosophers to be so interested in reasons is that they seem to be able to compete. For example, if on the one hand, you promised your friend to keep a secret, that is a reason that counts against telling anyone else, but if the secret is that they are having an affair with the spouse of another of your friends, that is a reason that counts in favor of telling, and to figure out what you should do, it seems like we have to weigh these reasons together to see which one is more important. But very few ethicists have gotten very far in thinking about the distinctive challenges… show more.
