Otto Neurath quotes:

Modern man receives a large part of his knowledge and general education by way of pictorial impressions, illustrations, photographs, films. Daily newspapers bring more pictures from year to year. In addition, the advertising business operates with optical signals as well as representations. Exhibitions and museums are indeed offspring of this visual hustle.

Words divide, pictures unite.

He who knows what best to omit is the best teacher.

We are like sailors who have to rebuild their ship on the open sea, without ever being able to dismantle it in dry-dock and reconstruct it from the best components.

We are like sailors who on the open sea must reconstruct their ship but are never able to start afresh from the bottom. Where a beam is taken away a new one must at once be put there, and for this the rest of the ship is used as support. In this way, by using the old beams and driftwood the ship can be shaped entirely anew, but only by gradual reconstruction.

To remember simplified pictures is better than to forget accurate figures.
