Mumford has drawn on every aspect of life to explain the machine and to trace its social results. "An extraordinarily wide-ranging, sensitive, and provocative book about a subject upon whichphilosophers have so far shed but little light" (Journal of Philosophy).

    It remains the one of the most widely read books about science to come out of the twentieth century.(Note: the book was first published in 1934, in German, with the title Logik der Forschung. It was "reformulated" into English in 1959. See Wikipedia for details.)

    This is a practical guide to the outdoor identification of all species of North American birds found regularly east of the Great Plains region.

    This book dispels some of the subject’s alarming aspects, starting at the very beginning and assuming no mathematical education.Written in a witty and engaging style, the text contains an illustrative example for every point, as well as absorbing glimpses into mathematical history and philosophy.Topics include the system of tens and other number systems; symbols and commands; first steps in algebra and algebraic notation; common fractions and equations; irrational numbers; algebraic functions; analytical geometry; differentials and integrals; the binomial theorem; maxima and minima; logarithms; and much more. Upon reaching the conclusion, readers will possess the fundamentals of mathematical operations, and will undoubtedly appreciate the compelling magic behind a subject they once dreaded.

    This concept of the umwelt has become enormously important within posthumanist philosophy, influencing such figures as Heidegger, Merleau-Ponty, Deleuze and Guattari, and, most recently, Giorgio Agamben, who has called Uexküll "a high point of modern antihumanism."A key document in the genealogy of posthumanist thought, A Foray into the Worlds of Animals and Humans advances Uexküll's revolutionary belief that nonhuman perceptions must be accounted for in any biology worth its name; it also contains his arguments against natural selection as an adequate explanation for the present orientation of a species' morphology and behavior. A Theory of Meaning extends his thinking on the umwelt, while also identifying an overarching and perceptible unity in nature. Those coming to Uexküll's work for the first time will find that his concept of the umwelt holds out new possibilities for the terms of animality, life, and the whole framework of biopolitics itself.
