CORE DEFINITION

A famous metaphor proposed by Otto Neurath: we are like sailors who must rebuild their ship on the open sea, unable to dismantle it and rebuild from scratch in a dry dock, but only to replace it plank by plank using existing materials while sailing.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Incremental reform thinking. It rejects Cartesian 'radical doubt' and 'starting from zero', teaching us to make local, piecemeal updates while keeping the system (knowledge system, social institutions, legacy code) running.

Anchor fast decisions

Neurath's metaphor: sailors cannot go ashore to dismantle and rebuild the ship, but must replace planks one by one while sailing. It rejects Cartesian 'radical doubt, starting from zero', advocating local, piecemeal updates within a running system (knowledge, institutions, code).

The Hedgehog and the Fox

The Hedgehog and the Fox is an essay by philosopher Isaiah Berlin that was published as a book in 1953. It was one of his most popular essays with the public. However, Berlin said, "I meant it as a kind of enjoyable intellectual game, but it was taken seriously. Every classification throws light on something". It has been compared to "an intellectual's cocktail-party game".
