The goal of thoughtlessness in design stems from understanding how we interact with the world. This observation was discussed extensively by Heidegger. He noted how, when using a hammer, we treat it as a nail-hitting thing. We don’t consider its function as a lever, nor how the weighted end has the advantage of accelerating the hammer’s descent, and that on contact it can propel its target forward. Instead, we need to hit nails, and immediately, without thought, we use the nail-hitting thing.
