Lean Logic, A dictionary for the future and how to survive it, by David Flemming Click here to take a quick look Click here to take a quick look

Lean Logic does not conform.

It is a community of essays about inventive, cooperative self-reliance in the face of great uncertainty.

Lean Logic acknowledges, with honesty, the challenges ahead in finding our way out of an economy that has all but destroyed the very foundations upon which it depends - the climate, the complex ecological system and the community and culture which gives meaning to life.

But rather than inducing despair, Lean Logic is rare in its ability to inspire optimism in the creativity and intelligence of humans to nurse our ecology back to health, to rediscover the importance of place and play, of community and culture, and of reciprocity and resilience.

It is not a book to read from start to finish. Begin in the middle, with something, anything, that sparks your interest, and let the signposts pull you through a chaotic web of ideas, brimming with humour and originality, with elegance and contradiction.

Lean Logic is a dictionary of empowerment.

Note that in 2016 Lean Logic was finally published, by Chelsea Green Publishing. That final edition is now the definitive version of Lean Logic, available through all good bookstores, or online at this link.

After David’s death his close friend and colleague Shaun Chamberlin spent several years editing and indexing the manuscript, as well as completing the endnotes and bibliography. Meanwhile Chelsea Green’s design team put an exceptional level of care and attention into a more attractive and usable layout (see sample spreads here and here), which has since won several design awards.

The final edition also features a new foreword from Jonathon Porritt, an editor’s preface, and several wood engravings selected or commissioned by Fleming that were inadvertently left out of his manuscript.

By contrast, this website sells the couple of hundred remaining copies of the original manuscript (as pictured above), which is now considered a collector’s item for the multiplying admirers of Fleming’s work.

They can be purchased for 20 for one copy, or 15 per copy for orders of two or more. Postage and packing in the UK is 5 per copy.

This is David Fleming’s original manuscript of 736 pages just as it was at the time of his sudden death. It was printed under hard cover in 2011, primarily for family and friends, and comprises David’s final draft, including endnotes, bibliography and many wonderful wood cuts and illustrations. All proceeds from sales are used to promote David’s work and passions, including TEQs (see below).

The preferred ordering process is to email orders@leanlogic.net specifying the desired number of copies, delivery address and payment method (cheque or online bank transfer). Alternatively, orders can be placed via Paypal:
