Karen L. Edwards, Milton and the Natural World: Science and Poetry in Paradise Lost (Cambridge: Cambridge University Press, 1999), xiii + 265pp, ISBN 0521643597 Although the question of Milton’s interest in the scientific debates of his day has been broached elsewhere, Karen L. Edwards is the first to highlight the full extent of Milton’s debt and contribution to experimental science in the seventeenth century and, in particular, to his imaginative and creative engagements with the natural world. In a writer so intellectually bold as Milton, it would indeed be surprising if he were not to have participated in the crucial debate of how to read the book of knowledge. As Edwards contends, ‘Milton would have considered it the duty of a writer of epic to embrace all the learning of his day, even if some of it was in the process of being discredited and some of it was still highly speculative.’ In the introductory chapter to Milton and the Natural World, Edwards situates her work within the contexts afforded by Milton studies and by recent work in the history and philosophy of science. Adopting Bourdieu’s notion of a ‘lag’, during which a population takes time to recognise and respond to a changed epistemological condition, Edwards deftly side-steps the interpretative paralysis of a Foucauldian model of discontinuity and rupture, and is able both to acknowledge competing discourses and fissures in Milton’s text and to appreciate the ways in which Milton utilises Renaissance poetics in order to assimilate, reconcile and reorder his heterogeneous material. The rest of Milton and the Natural World is divided into two parts. In the first part, Edwards sets out the interpretative strategies available to Milton and his seventeenth-century readers when set the task of understanding the book of the world. On the one hand is the symbolic or analogic hermeneutic that produced an encyclopaedic stock of plant lore from antiquity to the earlier Renaissance; on other hand is the experiential reading strategy developed by advocates of the ‘new science,’ by writers such as Thomas Browne, Robert Boyle, John Evelyn and Robert Hooke. Both reading strategies are present in Paradise Lost, Edwards argues, but it is the latter, with its close relationship to Protestant devotional practices, which Milton adopts as the dominant voice in his work: ‘there is a controlling discourse in Milton's fusing of the old and new philosophies, and it is the latter, I will argue. Milton is on this side of modernity.’ The fabulous and simply erroneous lore so wittily debunked in Thomas Browne’s Pseudodoxia Epidemica appears in Paradise Lost not because Milton believed it to be true, Edwards argues, but insofar as it is shown to constitute a misreading of the natural world. Perhaps the most important aspect of Milton and the Natural World is to show the ways in which the experimentalism of Milton's natural philosophy was informed by and in turn helped inform, his poetics. ‘To find “science” in Paradise Lost,’Edwards contends, ‘it is necessary to look very closely at the way the poetry works.’ In the second part of her book, therefore, Edwards examines the ways in which Milton treats specific aspects of the natural world, both flora and fauna, from the fantastic (the amphisbaena, the griffin, the azure rose) to the commonplace (the plane tree, lemon balm, the ant and bee) and to the contested area in-between. In so doing, Edwards herself expertly moves between a wide range of sources, including herbals, bestiaries, atlases, curiosity cabinets, travel narratives, botanical gardens and menageries, to show the varieties of knowledge that Milton and his contemporaries brought to their readings of the natural world and to poetry. By closely examining Milton’s use of sources and the interpretative decisions he encourages in his readers, Edwards is able to show how poetics and science work together to create an experience of uncertainty that is characteristic of the ‘new science’: ‘the poem consistently makes available new representational possibilities suggested by the experimental philosophy, and it does so with excitement, wit, and creative relish. What I see as the mark of experimentalism upon the poem’s depiction of a creature is this: the necessity for a reader’s imaginative engagement in the process of making meaning. This is, in part, because experimentalism in the mid-seventeenth century tends to open areas of scientific uncertainty which are poetically liberating.’ This interpretative uncertainty has perhaps not yet been fully acknowledged among historians of early modern science. As well as bringing fresh insights to familiar passages from Paradise Lost, Edwards makes important contributions to a number of other topics: her readings of Thomas Browne, Robert Hooke—whose Micrographia (1665) is represented in a number of illustrations—and Du Bartas are particularly memorable. Edwards’s enthusiasm for her material is infectious, and through a combination of insightful close reading and confident analyses of wider historical and theoretical issues, she has produced a work which is entirely consonant with the spirit and strategy of Paradise Lost. Written with grace and clarity, Edwards’s work is an education for the twenty-first-century reader. She writes: ‘Milton has so written the book of the world that its creatures, too, ask for and respond to continual re-reading and re-thinking. They disclose new beauty and new intricacy each time they are revisited.’ The same can be said for Milton and the Natural World. Jayne Archer University of Warwick
