The Clock Of The Long Now

Jun 15, 2026 | 5/5 stars

What if you thought of right Now as extending 10000 years in the past, the dawn of agriculture, to 10000 years in the future?

How does taking such a long-term view change what you choose to work on, how you take responsibility, how you relate to what’s around you?

I enjoyed this work quite a lot. It directly inspired multiple questions for me, like How can I produce Long Content? and What are examples of Slow Science?. In my personal journal, I have made a list of things in my life that will survive for decades and that I can take more responsibility for over the long-term. I am brainstorming Long Art ideas and how I might work with the CPV gardener to understand & improve the ecology of the garden. I have added many of the books mentioned in the text & from the Recommended Bibliography to my reading list.

I suspect the Long Now will be an extremely valuable ongoing lens for me.

Most interesting ideas from the book:

  • Six pace layers of civilization, from fastest to slowest
    • Fashion, Commerce, Infrastructure, Governance, Culture, Nature
  • The longer a view you take, the more selfishness and altruism merge
  • The Big Here, the Long Now
  • Slow Science (What are examples of Slow Science?)
  • Applied History
  • Permanence is constant renewal (Ise Shrine)
  • Physically written down words often have more permanence than digital artifacts
    • Is this still true given LLMs? Probably
  • It’s very difficult to know what future generations will value from today’s civilization
  • Unanticipated effect of the space program, which almost all environmentalists fought against (arguing we need to solve Earth’s problems before exploring space): pictures of Earth from space kicked off the environmental movement
  • You can always improve things as long as you’re prepared to wait
  • Parallel: biology often has systems that combine multiple timescales to have both stable identity and fast responsiveness (eg in epigenetics, histone modifications & DNA methylation); multiple timescales and multi-level organization are how any complex system works

Provenance: decided to read this book after reading https://gwern.net/about#long-content
