One of the Wall Street Journal's 10 Best Books of 2020 One of the New York Times's 100 Notable Books of 2020 A biography of J. B. S. Haldane, the brilliant and eccentric British scientist whose innovative predictions inspired Aldous Huxley’s Brave New World. J. B. S. Haldane’s life was rich and strange, never short on genius or drama—from his boyhood apprenticeship to his scientist father, who first instilled in him a devotion to the scientific method; to his time in the trenches during the First World War, where he wrote his first scientific paper; to his numerous experiments on himself, including inhaling dangerous levels of carbon dioxide and drinking hydrochloric acid; to his clandestine research for the British Admiralty during the Second World War. He is best remembered as a geneticist who revolutionized our understanding of evolution, but his peers hailed him as a polymath. One student called him “the last man who might know all there was to be known.” He foresaw in vitro fertilization, peak oil, and the hydrogen fuel cell, and his contributions ranged over physiology, genetics, evolutionary biology, mathematics, and biostatistics. He was also a staunch Communist, which led him to Spain during the Civil War and sparked suspicions that he was spying for the Soviets. He wrote copiously on science and politics in newspapers and magazines, and he gave speeches in town halls and on the radio—all of which made him, in his day, as famous in Britain as Einstein. It is the duty of scientists to think politically, Haldane believed, and he sought not simply to tell his readers what to think but to show them how to think. Beautifully written and richly detailed, Samanth Subramanian’s A Dominant Character recounts Haldane’s boisterous life and examines the questions he raised about the intersections of genetics and politics—questions that resonate even more urgently today.

J.B.S. Haldane (1892-1964), one of the founders of the science of population genetics, was also one of the greatest practitioners of the art of explaining science to the layperson. Haldane was a superb story-teller, as his essays and his children's books attest. In The Causes of Evolution he not only helped to marry the new science of genetics to the older one of evolutionary theory but also provided an accessible introduction to the genetical basis of evolution by natural selection. Egbert Leigh's new introduction to this classic work places it in the context of the ongoing study of evolution. Describing Haldane's refusal to be confined by a "System" as a "light-hearted" one, Leigh points out that we are now finding that "Haldane's questions are the appropriate next stage in learning how adaptation can evolve. We are now ready to reap the benefit of the fact that Haldane was a free man in the sense that really matters."

Can you name the creator of the Territorial Army, the British Expeditionary Force, the Imperial General Staff, and the Officers' Training Corps? The man who laid the foundation stones of MI5, MI6, the RAF, the LSE, Imperial College, the "redbrick" universities, and the Medical Research Council? This book restores Richard Burdon Haldane to his rightful place among the great men of British and Canadian history. Serving as war minister in the 1905 Liberal British government, his groundbreaking proposals on defence, education, and government structure were astonishingly ahead of his time – the very building blocks of modern Britain. Even the Canadian Constitution, as now interpreted, is unthinkable without Haldane. His ubiquitous networks ranged from Wilde to Einstein, Churchill to Carnegie, king to kaiser; his polymathic interests enabled pioneering cross-party, cross-sector cooperation. Yet in 1915 he was ejected from the Lord Chancellorship, unjustly vilified by an ignorant press campaign as a German sympathizer. John Campbell charts these ups and downs, reveals the intensely personal side of Haldane through previously unpublished love letters, and shows his enormous relevance in our search for just societies and states today. Amidst political and national instability, it is surely now right to reinstate Haldane as an outstanding example of true statesmanship.

Haldane, Mayr, and Beanbag Genetics presents a summary of the classic exchange between two great biologists - J.B.S. Haldane and Ernst Mayr - regarding the value of the contributions of the mathematical school represented by J.B.S. Haldane, R.A. Fisher and S. Wright to the theory of evolution. Their pioneering contributions from 1918 to the 1960s dominated and shaped the field of population genetics, unique in the annals of science. In 1959, Mayr questioned what he regarded as the beanbag genetic approach of these pioneers to evolutionary theory, "an input or output of genes, as the adding of certain beans to a beanbag and the withdrawing of others." In 1964, Mayr's contention was refuted by Haldane in a remarkably witty, vigorous and pungent essay, "A defense of beanbag genetics" which compared the mathematical theory to a scaffolding within which a reasonably secure theory expressible in words may be built up. Correspondence between Haldane and Mayr is included. Beanbag genetics has come a long way since 1964. Mayr's (1959) critique of simple uncomplicated population genetics is no longer valid. Population genetics today includes much more than Mayr's beanbag genetics. Population genetics models now include multiple factors, linkage, dominance and epistasis. These may be regarded as the advanced beanbag models. Furthermore, population genetics and developmental genetics have become interdependent. Contemporary beanbag genetics includes molecular clocks, nucleotide diversity, coalescence and DNA-based phylogenetic trees, along with the four major holdovers from classical genetics, mutation, selection, migration and random drift. Molecular genetics has made it possible to study evolution rates at the nucleotide level. It is also possible today to compare DNA similarities and divergence in diverse species of animals and plants, which were not previously crossable.

In this awaited follow up to his book Faithful Reason, the well-known philosopher and Catholic thinker John Haldane brings his unrivalled insight to bear on questions of the existence of God and the nature and destiny of the human soul. His arguments weave elements drawn from philosophy of mind, epistemology and aesthetics, together with recurrent features of human experience to create a structure that simultaneously frames and supports ideas such as that the cosmos is a creation, human beings transcend their material composition, and that human fulfilment lies beyond death. As in many of his other writings this volume blends themes from Aquinas with insights drawn from analytical philosophy and further establishes John Haldane as the leading 'analytical thomist'.

John Scott Haldane (1860-1936) was one of the greatest and most colourful of British scientists, acknowledged as the leading physiologist of the Victorian era. The most successful serial self-experimenter in the history of science, Haldane crawled through the carnage of underground explosions, locked himself in sealed chambers, breathed in lethal cocktails of gases, sampled his own blood, burned and healed his own flesh, and experimented on his own children in an obsessive push to understand the nature of human respiration. What is expired air? How can you make coal mines safer? What does carbon monoxide do to people? These are just some of the vital questions to which Haldane provided the answers, saving thousands of lives in the process. He also designed the first space-suit and invented the gas-mask, among many other innovations and contributions we still benefit from today. Entertaining and enlightening in equal measure, Martin Goodman's lively and revealing biography casts new light on one of the greatest eccentrics of British scientific and intellectual life.
