This book explores the development of hybrid corn, the history of eugenics, human genetics, the nature-nurture debate, the origins of the Marxian concept of proletarian science, the shift in the meaning of "fitness" in evolutionary theory, the practice of normal science in Nazi Germany, and the making and selling of science textbooks. While the topics are diverse, a common theme unites them - each explores links between biological science, social power, and public policy.

The lavish array of organisms known as "biodiversity" is an intricately linked web that makes the Earth a uniquely habitable plane. In this book, a noted science writer examines the threats posed to humans by the loss of biodiversity and explains key findings from the ecological sciences. It is the first book of its kind to clearly explains the practical consequences of declining biodiversity of ecosystem hjealth and function and, consequently, on human society.

The study of chaotic systems has become a major scientific pursuit in recent years, shedding light on the apparently random behaviour observed in fields as diverse as climatology and mechanics. InThe Essence of Chaos Edward Lorenz, one of the founding fathers of Chaos and the originator of its seminal concept of the Butterfly Effect, presents his own landscape of our current understanding of the field. Lorenz presents everyday examples of chaotic behaviour, such as the toss of a coin, the pinball's path, the fall of a leaf, and explains in elementary mathematical strms how their essentially chaotic nature can be understood. His principal example involved the construction of a model of a board sliding down a ski slope. Through this model Lorenz illustrates chaotic phenomena and the related concepts of bifurcation and strange attractors. He also provides the context in which chaos can be related to the similarly emergent fields of nonlinearity, complexity and fractals. As an early pioneer of chaos, Lorenz also provides his own story of the human endeavour in developing this new field. He describes his initial encounters with chaos through his study of climate and introduces many of the personalities who contributed early breakthroughs. His seminal paper, "Does the Flap of a Butterfly's Wing in Brazil Set Off a Tornado in Texas?" is published for the first time.

Substance and Essence in Aristotle is a close study of Aristotle's most profound—and perplexing—treatise: Books VII-IX of the Metaphysics. These central books, which focus on the nature of substance, have gained a deserved reputation for their difficulty, inconclusiveness, and internal inconsistency. Despite these problems, Witt extracts from Aristotle's text a coherent and provocative view about sensible substance by focusing on Aristotle's account of form or essence. After exploring the context in which Aristotle's discussion of sensible substance takes place, Witt turns to his analysis of essence. Arguing against the received interpretation, according to which essences are classificatory, Witt maintains that a substance's essence is what causes it to exist. In addition, Substance and Essence in Aristotle challenges the orthodox view that Aristotelian essences are species-essences, defending instead the controversial position that they are individual essences. Finally, Witt compares Aristotelian essentialism to contemporary essentialist theories, focusing in particular on Kripke's work. She concludes that fundamental differences between Aristotelian and contemporary essentialist theories highlight important features of Aristotle's theory and the philosophical problems and milieu that engendered it.

A New 2023 translation into English from the original manuscript, with an introduction, glossary of Feuerbachian terminology and a timeline of his life and works. "The Essence of Religion" is a philosophical work published in 1841 that critiques the nature and origins of religious belief, arguing for a Darwinian-historical origin for religion, and a materialistic worldview. In this work, Feuerbach argues that religion is a product of human imagination and projection, and that its true essence can only be understood by examining the human mind and its relationship to the natural world. Schopenhauer and Nietzsche both take their satirical criticism about religion from Feuerbach, and every aspect of Marxism can be found here in Marx's favorite Philosopher. Feuerbach is a critical figure in the development of not merely Marxism, but Materialistic Humanism in general. Feuerbach is critical to understanding Marx. This is Volume VI in the 2023 The Complete Works of Ludwig Feuerbach by Newcomb Livraria Press
