"The 125 previously unpublished letters of this collection, housed at the Stanford University Library - document the broad range of Edward F. Ricketts's interests and accomplishments during the last 12 and most productive years of his life. His handbook on Pacific marine life, Between Pacific Tides, is still in print, now in its fifth edition. The biologist's devotion to ecological conservation and his evolving philosophy of science as a cross-disciplinary, holistic pursuit led to the publication of The Sea of Cortez. This landmark collaborative work with Steinbeck examines marine life off the Baja Peninsula from both ecological and spiritual perspectives. Many of Rickett's letters discuss his studies of the Pacific littoral and his theories of "phalanx" and transcendence. Epistles to family members, often tender and humorous, add dimension and depth to Steinbeck's mythologized depictions of Ricketts." "Editor Katharine A. Rodger has enriched the correspondence with an introduction, a biographical essay, and a list of works cited. The book will be important for students of John Steinbeck and the development of 20th-century American fiction, as well as for those interested in the history of science, especially in the fields of marine biology and ecology."--BOOK JACKET.
