From popular culture to politics to classic novels, quintessentially American texts take their inspiration from the idea of infinity. In the extraordinary literary century inaugurated by Ralph Waldo Emerson, the lyric too seemed to encounter possibilities as limitless as the U.S. imagination. This raises the question: What happens when boundlessness is more than just a figure of speech? Exploring new horizons is one thing, but actually looking at the horizon itself is something altogether different. In this carefully crafted analysis, James von der Heydt shines a new light on the lyric craft of Emily Dickinson, Robert Frost, Elizabeth Bishop, and James Merrill and considers how their seascape-vision redefines poetry's purpose.

Emerson famously freed U.S. literature from its past and opened it up to vastness; in the following century, a succession of brilliant, rigorous poets took the philosophical challenges of such freedom all too seriously. Facing the unmarked horizon, Emersonian poets capture—and are captured by—a stark, astringent version of human beauty. Their uncompromising visions of limitlessness reclaim infinity's proper legacy—and give American poetry its edge. Von der Heydt's book recovers the mystery of their world.

Celebrated as a courtesan and poet, and as a woman of great intelligence and wit, Tullia d'Aragona (1510–56) entered the debate about the morality of love that engaged the best and most famous male intellects of sixteenth-century Italy. First published in Venice in 1547, but never before published in English, Dialogue on the Infinity of Love casts a woman rather than a man as the main disputant on the ethics of love.

Sexually liberated and financially independent, Tullia d'Aragona dared to argue that the only moral form of love between woman and man is one that recognizes both the sensual and the spiritual needs of humankind. Declaring sexual drives to be fundamentally irrepressible and blameless, she challenged the Platonic and religious orthodoxy of her time, which condemned all forms of sensual experience, denied the rationality of women, and relegated femininity to the realm of physicality and sin. Human beings, she argued, consist of body and soul, sense and intellect, and honorable love must be based on this real nature.

By exposing the intrinsic misogyny of prevailing theories of love, Aragona vindicates all women, proposing a morality of love that restores them to intellectual and sexual parity with men. Through Aragona's sharp reasoning, her sense of irony and humor, and her renowned linguistic skill, a rare picture unfolds of an intelligent and thoughtful woman fighting sixteenth-century stereotypes of women and sexuality.

By virtue of the originality and depth of its thought, Emmanuel Levinas’s masterpiece, Totality and Infinity: An Essay on Exteriority, is destined to endure as one of the great works of philosophy. It is an essential text for understanding Levinas’s discussion of “the Other,” yet it is known as a “difficult” book. Modeled after Norman Kemp Smith’s commentary on Kant’s Critique of Pure Reason, Levinas’s Existential Analytic guides both new and experienced readers through Levinas’s text. James R. Mensch explicates Levinas’s arguments and shows their historical referents, particularly with regard to Heidegger, Husserl, and Derrida. Students using this book alongside Totality and Infinity will be able to follow its arguments and grasp the subtle phenomenological analyses that fill it.

These selections from Le système du monde, the classic ten-volume history of the physical sciences written by the great French physicist Pierre Duhem (1861-1916), focus on cosmology, Duhem's greatest interest. By reconsidering the work of such Arab and Christian scholars as Averroes, Avicenna, Gregory of Rimini, Albert of Saxony, Nicole Oresme, Duns Scotus, and William of Occam, Duhem demonstrated the sophistication of medieval science and cosmology.
