Liz Waldner's bold new collection takes its title and its inspiration from Definition 1 of Euclid's Elements of Geometry. Its six sections—point, line, circle, square, triangle, and point again—are explorations of various kinds of longing and loss—sex, death, exile, story, love, and time. Drawing from culture high and low—Eno and Aquinas, Lassie and Donne, Silicon Valley and Walden Pond—these poems offer proof of and proof against the “mortal right-lined circle” of memory and identity. The innocence and Keatsian beauty of Euclid's geometry become poignant from a perspective that encompasses all that is non-Euclidean as well as space, time, and the theory of matter. With rare wit and linguistic daring, Waldner opens resonant channels of communication that show there is indeed more than meets the eye—or the mind—in her poems. Hand to Mouth (Twist and Shout) Cold comes slow up out of the darkness among the leaves that smell so good when bruised Do you, too, recognize me god so soon? Her First Reckoning Pour wine into vessels the violet of woods, wine of the reddening stars. You are god, you can do it. Your lover calls you St. John the Conqueror. I have heard her. This is the name of a root. Asperge the thousands and thousands of rooms in which photosynthesis promises sun to the acolyte cells. Rain yourself on a leaf. Birch. The bark is malleable as mushroom flesh. Show that you know me. Scratch out my name with this tree. My name of trees. On the day I arrive at the door of my death, myself now hard to tell from the trees that had hid it from me, I will demand that you love me. You made me like this. Why did you make me like this? Transitive, Intransitive: Extemporary Measures Two crows above the marsh: sew. Stitch the seventeen sleek shades of blue to the shadow-patterned greens below. See fit to make me a suitable view who having nowhere to else to go might as well wear this world well. Llama necks periscope the view: yonder, across the water, you testing the air now a crow chases a redwing blackbird through. What can I show you who sees I don't believe? For now, what the eye of the needle sees: through through through: clouds, birds, me, trees; soon: in, out, with, to; something moving, something moved: a stitch in time's an avenue, future's sutures' revenue— “the shining hour” improved.

Rarely has the history or philosophy of mathematics been written about by mathematicians, and the analysis of mathematical texts themselves has been an area almost entirely unexplored. Figures of Thought looks at ways in which mathematical works can be read as texts, examines their textual strategies and demonstrates that such readings provide a rich source of philosophical issues regarding mathematics: issues which traditional approaches to the history and philosophy of mathematics have neglected. David Reed, a professional mathematician himself, offers the first sustained and critical attempt to find a consistent argument or narrative thread in mathematical texts. In doing so he develops new and fascinating interpretations of mathematicians' work throughout history, from an in-depth analysis of Euclid's Elements, to the mathematics of Descartes and right up to the work of contemporary mathematicians such as Grothendeick. He also traces the implications of this approach to the understanding of the history and development of mathematics.

Starting with Marx and Freud, scholars have attempted to identify the primary ethical challenge of capitalism. They have named injustice, inequality, repression, exploitative empires, and capitalism's psychic hold over all of us, among other ills. Nimi Wariboko instead argues that the core ethical problem of capitalism lies in the split nature of the modern economy, an economy divided against itself. Production is set against finance, consumption against saving, and the future against the present. As the rich enjoy their lifestyle, their fellow citizens live in servitude. The economy mimics the structure of our human subjectivity as Saint Paul theorizes in Romans 7: the law constitutes the subject as split, traversed by negativity. The economy is split, shot through with a fundamental antagonism. This fundamental negativity at the core of the economy disturbs its stability and identity, generating its destructive drive. The Split Economy develops a robust theoretical framework at the intersection of continental philosophy, psychoanalytic theory, theology, and political economy to reveal a fundamental dynamic at the heart of capitalism.
