title: Longues lettres > Since the spring of 2013, Artangel and the Longplayer Trust have been inviting thinkers and writers from a wide variety of disciplines to engage in a chain of written correspondence on the subject of long-term thinking. The Longplayer Letters are a chain of written correspondence on the subject of long-term thinking. Unfolding slowly over time, the letters form a written conversation in which each correspondent answers the past author in addressing the next – it is a dialogical relay, very much in the spirit of the Long Conversations. > > *[The Longplayer Letters](http://longplayer.org/letters/)* ([cache](/david/cache/e929e719bb15b50031407d1c4942d99b/)) [Thomas](https://oncletom.io/) m’invite à aller découvrir ce projet, probablement suite à [mes interrogations](/david/stream/2015/11/23/). Je trouve le projet intéressant et motivant, je commence à réfléchir aux personnes qui pourraient s’embarquer dans le projet. Puis je réalise que je n’ai répondu à *aucune* lettre reçue de sa part au cours de ces dernières années. Douce ironie… Culpabilité renforcée… Remise en question…
