Seven Generations
In one line Haudenosaunee teaching asks leaders to weigh each decision by its effect seven generations ahead.
The Haudenosaunee, or Six Nations, a confederacy that includes the Mohawk, Oneida, Onondaga, Cayuga, Seneca and Tuscarora, have long governed by the Great Law of Peace. It joined once-warring nations into a league in which chiefs deliberate in councils and seek agreement.
A principle often linked to that tradition asks decision-makers to consider the effects of their choices on the seventh generation to come. People alive now are the link between ancestors who left them the world and descendants who will inherit it. A good decision is one those far-off descendants could thank you for.
Scholars note that the exact wording is hard to trace in early records, but the principle is widely taught by Haudenosaunee leaders today, and it has shaped thinking about sustainability far beyond them.
Go deeper
Indigenous philosophies are many, not one. Hundreds of nations in the Americas, and many more peoples worldwide, have their own languages, laws and ways of reasoning. Lessons like this one pick out a single strand, and they work best as an invitation to learn from the people who hold the tradition, rather than as a summary of it.
The town reservoir
A town council can build a cheap reservoir now that will silt up in thirty years, or a costlier one that will last a century.
Under pressure to keep taxes down, they almost choose the cheap one. A member asks who will pay for the silted reservoir: their grandchildren and great-grandchildren. The council chooses the lasting design and spreads the cost.
Try this today Before your next big decision, ask who will live with its effects in a century or more, and what they would say.
