After its rediscovery in 1417, Lucretius’s Epicurean didactic poem De Rerum Natura threatened to supply radicals and atheists with the one weapon unbelief had lacked in the Middle Ages: good answers. Scholars could now challenge Christian patterns of thought by employing the theory of atomistic physics, a sophisticated system that explained natural phenomena without appeal to divine participation, and argued powerfully against the immortality of the soul, the afterlife, and a creator God.

Ada Palmer explores how Renaissance readers, such as Machiavelli, Pomponio Leto, and Montaigne, actually ingested and disseminated Lucretius, and the ways in which this process of reading transformed modern thought. She uncovers humanist methods for reconciling Christian and pagan philosophy, and shows how ideas of emergent order and natural selection, so critical to our current thinking, became embedded in Europe’s intellectual landscape before the seventeenth century. This heterodoxy circulated in the premodern world, not on the conspicuous stage of heresy trials and public debates, but in the classrooms, libraries, studies, and bookshops where quiet scholars met the ideas that would soon transform the world. Renaissance readers—poets and philologists rather than scientists—were moved by their love of classical literature to rescue Lucretius and his atomism, thereby injecting his theories back into scientific discourse.

Palmer employs a new quantitative method for analyzing marginalia in manuscripts and printed books, exposing how changes in scholarly reading practices over the course of the sixteenth century gradually expanded Europe’s receptivity to radical science, setting the stage for the scientific revolution.

In Reading Wittgenstein with Anscombe, Going On to Ethics, Cora Diamond follows two major European philosophers as they think about thinking, as well as about our ability to respond to thinking that has miscarried or gone astray. Acting as both witness to and participant in the encounter, Diamond provides fresh perspective on the importance of the work of these philosophers and the value of doing philosophy in unexpected ways.

Diamond begins with the Tractatus (1921), in which Ludwig Wittgenstein forges a link between thinking about thought and the capacity to respond to misunderstandings and confusions. She then considers G. E. M. Anscombe’s An Introduction to Wittgenstein’s Tractatus (1959), in which Anscombe, through her engagement with Wittgenstein, further explores the limits of thinking and the ability to respond to thought that has gone wrong. Anscombe’s book is important, Diamond argues, in challenging contemporary assumptions about what philosophical problems are worth considering and about how they can be approached. Through her reading of the Tractatus, Anscombe exemplified an ethics of thinking through and against the grain of common preconceptions. The result drew attention to the questions that mattered most to Wittgenstein and conveyed with great power the nature of his achievement.

Diamond herself, in turn, challenges Anscombe on certain points, thereby further carrying out just the kind of ethical work Wittgenstein and Anscombe each felt was crucial to getting things right. Through her textured engagement with her predecessors, Diamond demonstrates what genuinely independent thought is able to achieve.

Transcendentalism never came to an end in America. It just went underground for a stretch, but is back in full force in Robert Brandom’s new book. Brandom takes up Kant and Hegel and explores their contemporary significance as if little time had expired since intellectuals gathered around Emerson in Concord to discuss reason and idealism, selves, freedom, and community. Brandom’s discussion belongs to a venerable tradition that distinguishes us as rational animals, and philosophy by its concern to understand, articulate, and explain the notion of reason that is thereby cast in that crucial demarcating role.

An emphasis on our capacity to reason, rather than merely to represent, has been growing in philosophy over the last thirty years, and Robert Brandom has been at the center of this development. Reason in Philosophy is the first book that gives a succinct overview of his understanding of the role of reason as the structure at once of our minds and our meanings—what constitutes us as free, responsible agents. The job of philosophy is to introduce concepts and develop expressive tools for expanding our self-consciousness as sapients: explicit awareness of our discursive activity of thinking and acting, in the sciences, politics, and the arts. This is a paradigmatic work of contemporary philosophy.

Unpacking the central role of the unconscious in the relationship between mind and world

Over a series of careful readings and accessible discussions, prefaced by a foreword from Eric Santner, Dominik Finkelde analyzes the central role of the unconscious in the relationship between mind and world. Moving beyond Freud, Kant, and Hegel and toward the contemporary work of the Ljubljana School, he explores how humans relate to facts and the influence of the unconscious on questions regarding truth, perception, and meaning.

Aspects of recognition and unconscious processes of transference are at stake in these fundamental questions of perception and knowledge, though these have been widely ignored in epistemological and ontological debates in contemporary philosophy. Finkelde draws on both the continental and analytic traditions, ultimately building from the work of current-day interlocutors to interrogate questions concerning the influence of enigmatic signifiers, the role of sublime objects of ideology, the importance of fantasy cultivation and transgression, and the power of jouissance as an ontological factor.

“Compact and engaging, Retrieving Realism is more approachable than its weighty subject matter might predict…[An] adventurous combination of arguments and mixing of philosophical cultures.” —Boston Review

“A picture held us captive,” writes Wittgenstein in the Philosophical Investigations, describing the powerful image of mind that underlies the modern epistemological tradition from Descartes onward. Retrieving Realism offers a radical critique of the Cartesian epistemic picture that has captivated philosophy for too long and restores a realist view affirming our direct access to the everyday world and to the physical universe.

According to Descartes, knowledge exists in the form of ideas in the mind that purportedly represent the world. This “mediational” epistemology—internal ideas mediating external reality—continues to exert a grip on Western thought, and even philosophers such as Quine, Rorty, and Davidson who have claimed to refute Descartes remain imprisoned within its regime. As Hubert Dreyfus and Charles Taylor show, knowledge consists of much more than the explicit representations we formulate. We gain knowledge of the world through bodily engagement with it—by handling things, moving among them, responding to them—and these forms of knowing cannot be understood in mediational terms. Dreyfus and Taylor also contest Descartes’s privileging of the individual mind, arguing that much of our understanding of the world is necessarily shared.

Once we deconstruct Cartesian mediationalism, the problems that Hume, Kant, and many of our contemporaries still struggle with—trying to prove the existence of objects beyond our representations—fall away, as does the motivation for nonrealist doctrines. We can then begin to describe the background everyday world we are absorbed in and the universe of natural kinds discovered by science.

In this first comprehensive study of the effect of Lucretius's De rerum natura on Florentine thought in the Renaissance, Alison Brown demonstrates how Lucretius was used by Florentine thinkers—earlier and more widely than has been supposed—to provide a radical critique of prevailing orthodoxies.

To answer the question of why ordinary Florentines were drawn to this recently discovered text, despite its threat to orthodox Christian belief, Brown tracks interest in it through three humanists—the most famous of whom was Machiavelli—all working not as philologists but as practical administrators and teachers in the Florentine chancery and university. Interpreting their direct use of Lucretius within the context of mercantile Florence, Brown highlights three dangerous themes that had particular appeal: Lucretius's attack on superstitious religion and an afterlife; his pre-Darwinian theory of evolution; and his atomism, with its theory of free will and the chance creation of the world.

The humanists' challenge to established beliefs encouraged the growth of a "Lucretian network" of younger, politically disaffected Florentines. Brown thus adds a missing dimension to our understanding of the "revolution" in sixteenth-century political thinking, as she enriches our definition of the Renaissance in a context of newly discovered worlds and new social networks.

The turmoil and brutality of the twentieth century have made it increasingly difficult to maintain faith in the ability of reason to fashion a stable and peaceful world. After the ravages of global conflict and a Cold War that divided the world's loyalties, how are we to master our doubts and face the twenty-first century with hope?

In Return to Reason, Stephen Toulmin argues that the potential for reason to improve our lives has been hampered by a serious imbalance in our pursuit of knowledge. The centuries-old dominance of rationality, a mathematical mode of reasoning modeled on theory and universal certainties, has diminished the value of reasonableness, a system of humane judgments based on personal experience and practice. To this day, academic disciplines such as economics and professions such as law and medicine often value expert knowledge and abstract models above the testimony of diverse cultures and the practical experience of individuals.

Now, at the beginning of a new century, Toulmin sums up a lifetime of distinguished work and issues a powerful call to redress the balance between rationality and reasonableness. His vision does not reject the valuable fruits of science and technology, but requires awareness of the human consequences of our discoveries. Toulmin argues for the need to confront the challenge of an uncertain and unpredictable world, not with inflexible ideologies and abstract theories, but by returning to a more humane and compassionate form of reason, one that accepts the diversity and complexity that is human nature as an essential beginning for all intellectual inquiry.

Milton’s Great Poems—Paradise Lost, Paradise Regained, and Samson Agonistes—are here examined in the light of his lifelong commitment to the English revolutionary cause. The poems, Joan Bennett shows, reflect the issues Milton had dealt with in theological and public policy debate, foreign diplomacy, and propaganda; moreover, they work innovatively with these issues, reaching in epic and tragedy answers that his pamphlets and tracts of the past twenty years had only partially achieved. The central issue is the nature and possibility of human freedom, or “Christian liberty.” Related questions are the nature of human rationality, the meaning of law, of history, of individuality, of society, and—everywhere—the problem of evil.

The book offers a revisionist position in the history of ideas, arguing that Renaissance Christian humanism in England descended not from Tudor to Stuart Anglicanism but from Tudor Anglicanism to revolutionary Puritanism. Close readings are offered of texts by Richard Hooker, Milton, and a range of writers before and during the revolutionary period. Not only theological and political positions but also political actions taken by the authors are compared. Milton's poems are studied in the light of these analyses.

The concept of “radical Christian humanism” moves current Milton criticism beyond the competing conceptions of Milton as the poet of democratic liberalism and the prophet of revolutionary absolutism. Milton's radical Christian humanism was built upon pre-modern conceptions and experiences of reason that are not alien to our time. It stemmed from, and resulted in, a religious commitment to political process which his poems embody and illuminate.
