"All 21 cards of the Mollison Permaculture Ethics and Design Principles card set are now free to download from <www.permaculturefundamentals.com/>. These are the original permaculture ethics and design principles from the writings of Bill Mollison, the father of permaculture and developer of the Permaculture Design Certificate (PDC).
I first taught the PDC in 1993, and this arrangement of the original ethics and principles from Permaculture: A Designers' Manual (Mollison 1988) and Introduction to Permaculture (Mollison and Slay 1992) came about after many years teaching permaculture and running permaculture projects. The cards are organised into ethics, energy principles, component placement principles, principles from nature, and attitudinal principles. It is these attitudinal principles, which along with the ethics are the 'heart and soul' of permaculture, that are often missing from condensed versions of the permaculture principles. The cards are designed to be printed as 6x4 photos, as this is often the cheapest form of high quality printing if you only want a small print run."
