To understand reality is not the same as to know about outward events. It is to perceive the essential nature of things. The best-informed man is not necessarily the wisest. Indeed there is a danger that precisely in the multiplicity of his knowledge he will lose sight of what is essential. But on the other hand, knowledge of an apparently trivial detail quite often makes it possible to see into the depth of things. And so the wise man will seek to acquire the best possible knowledge about events, but always without becoming dependent upon this knowledge. To recognize the significant in the factual is wisdom.

– Dietrich Bonhoeffer

The happiness that is genuinely satisfying is accompanied by the fullest exercise of our faculties and the fullest realization of the world in which we live.

-Bertrand Russell
