It’s hard to know if something we make is good, yet it’s an important question. We keep building systems with parasitical business models, addictive personalities and long-term side effects. Classic performance measures, like business growth, make economic sense, but there are deeper social, environmental and cultural issues at stake. Instead, I propose a set of five principles, curated from the best of philosophy, history, economics, science and design. By evaluating the things we make according to a set of concrete principles we can create products, services and systems that are in balance with the world.
