“A monumental achievement, David Fleming’s Lean Logic is an encyclopedic guide to the crisis of industrial civilization. I challenge anyone to read as much as a page of it without finding at least one insight worth serious reflection. Individuals, families, and communities will find it invaluable as a guide to navigating the troubled waters of the future.”--John Michael Greer, author of The Long Descent and After Progress

“The only scientific question left to us: how can we ensure a future for humanity? That includes: how do we free ourselves from capitalism, the form of social organisation that is destroying us? And how do we create something else? This book is a thoughtful and imaginative contribution to the debate about humanity’s future.”--John Holloway, sociologist; author of Change the World Without Taking Power and Crack Capitalism

“David Fleming’s eye was sharp, and his words had a way of getting right to the heart of the matter. This book is remarkable and scintillating; the product of a truly original mind.”--Paul Kingsnorth, cofounder, The Dark Mountain Project; author of The Wake

“In my words it's half encyclopaedia, half commonplace book, half a secular bible, half survival guide, half . . . yes, that's a lot of halves, but I hope you get the picture. I have never encountered a book that is so hard to characterise yet so hard, despite its weight, to put down. Lean Logic is neither a policy manifesto nor a dry technical guide. It's an incredibly nourishing cultural and scientific treasure trove.”--John Thackara, founder and director, Doors of Perception; author of How to Thrive in the Next Economy

“David Fleming was a walking encyclopaedia of ecological knowledge and wisdom. His brilliance, good humour, and deep insight were legendary and unforgettable. His writing, too, was of the highest calibre—witty, entertaining, profound, informative, and transformative. These books of his give us the opportunity to savour the great treasure that was his mind. To read them is to gain a superb education in ecology from one of the greatest masters in the field.”--Dr. Stephan Harding, resident ecologist, Schumacher College; author of Animate Earth

"A splendid smorgasbord, Lean Logic provides rare insight into some of the key issues of our time! Fleming's underlying vision of a future founded in a reclaimed richness of community, culture, and conversation is both heartening and timely."--Helena Norberg-Hodge, author of Ancient Futures; director of The Economics of Happiness

“David Fleming predicts environmental catastrophe but also proposes a solution that stems from the real motives of people and not from some comprehensive political agenda. He writes lucidly and eloquently of the moral and spiritual qualities on which we might draw in our 'descent' to a Lean Economy. His highly poetic description of these qualities is neither gloomy nor self-deceived but tranquil and inspiring. All environmental activists should read him and learn to think in his cultivated and nuanced way.”--Roger Scruton, writer and philosopher; author of over thirty books, including Green Philosophy

“This is an extraordinary book, uncategorisable, driven by a great rolling intellectual curiosity. Fleming fathomed the depth of the mess in which we find ourselves and left us clues as to how we might find our way through that mess.”--Dougald Hine, cofounder, The Dark Mountain Project

“David Fleming’s lifework is nothing less than an encyclopedia of the timeless art of living, encompassing the art of building enlivening communities, the art of allowing the economy to serve life and creativity, and the art of unmasking invisible brainwashing. Fleming has written a guide to becoming an authentic individual and to recognizing toxic relationships on every level of material and personal exchange. This is a serious guide to health on every level of relationships and at the same time a deeply humorous read. Whether the breakdown of technical civilisation will come (as Fleming is convinced) or humanity will just carry on muddling through as always, this encyclopedia of manners, grace, and style will make the reader’s life more wonderful and thus inevitably help to build a saner society.”--Andreas Weber, PhD, author of The Biology of Wonder

“David Fleming was the soul of provocative, exciting, and creative thought, and it was always a thought-provoking and pleasure-promoting experience to meet him. Amongst many virtues, his approach to climate change and ecology embraced the commons. Seeing this as a solution, with collective decision-making leading to a better future, was at the heart of his work. I am sure that Elinor Ostrom, who won a Nobel Prize for her work on the commons, would have appreciated David's comment that putting government in charge of commons was like placing the fox in control of the chicken coop. It is so sad that David is no longer with us, but his words are; these books are full of insight and enjoyment. I hope his laughter and enlightenment spread far and wide through new readers as well as those of us familiar with his thoughts already.”--Derek Wall, author of Economics After Capitalism and the forthcoming Elinor Ostrom’s Rules for Radicals

“For me originality, passion, commitment, and sincerity are the words which describe David Fleming. All these qualities are present in his writing. His lifelong championing of Tradable Energy Quotas, one of the very few instruments which promote sustainable consumption in a progressive rather than regressive way thereby combining environmental gain with a simultaneous transfer of resources from richer to poorer people, propels him to an honoured place in the pantheon of green campaigners.”--Tim Yeo, former UK Minister for the Environment and Chair of the House of Commons Energy and Climate Change Select Committee

“Our current public discourse on such problems as resource depletion, climate change, and the economy is often hopelessly muddled; this book brings light and transparency. David Fleming didn’t tell us what to think but rather how to avoid cognitive fallacies that masquerade as reason. Lean Logic is an instant classic that was many years in the making, and it should be essential reading for environmentalists, economists, policy makers, and anyone who wants greater clarity in understanding the most important issues of our time.”--Richard Heinberg, senior fellow, Post Carbon Institute

“David Fleming gives a remarkable overview of our present situation and of possible future scenarios. His writing is clear, witty, insightful, and wise. Lean Logic is a delight to dip into, and every time I do so I feel refreshed. It is a work of genius.”--Rupert Sheldrake, PhD, author of The Science Delusion
