Imagine a world where everyone was constantly learning, a world where what you wondered was more interesting than what you knew, and curiosity counted for more than certain knowledge. Imagine a world where what you gave away was more valuable than what you held back, where joy was not a dirty word, where play was not forbidden after your eleventh birthday. Imagine a world in which the business of business was to imagine worlds people might actually want to live in someday. Imagine a world created by the people, for the people not perishing from the earth forever.

From The Cluetrain Manifesto by Rick Levine, Christopher Locke, Doc Searls and David Weinberger

Except in exceptional circumstances, I don’t like consulting books on matters which seem to me to be capable of being worked upon and dealt with through isolated mental activity, on the basis of direct personal observation.

Paul Valéry

The things I most like to read, which force me to read them – and re-read them – are those I feel are moving me forward the most, which are not concerned with local matters, but growth, promise, extension – an outward detour which leads me back to myself, more enlightened and better armed.

Paul Valéry

Many of our examples suggest that clarity and excellence in thinking is very much like clarity and excellence in the display of data. When principles of design replicate principles of thought, the act of arranging information becomes an act of insight.
