Once you have learned to ask questions - relevant and appropriate and substantial questions - you have learned how to learn and no one can keep you from learning whatever you want or need to know.

The way in which the photograph records experience is also different from the way of language. Language makes sense only when it is presented as a sequence of propositions. Meaning is distorted when a word or sentence is, as we say, taken out of context; when a reader or listener is deprived of what was said before, and after. But there is no such thing as a photograph taken out of context, for a photograph does not require one. In fact, the point of photography is to isolate images from context, so as to make them visible in a different way.

Television is altering the meaning of 'being informed' by creating a species of information that might properly be called disinformation. Disinformation does not mean false information. It means misleading information - misplaced, irrelevant, fragmented or superficial information - information that creates the illusion of knowing something, but which in fact leads one away from knowing.

A book is an attempt to make through permanent and to contribute to the great conversation conducted by authors of the past. […] The telegraph is suited only to the flashing of messages, each to be quickly replaced by a more up-to-date message. Facts push other facts into and then out of consciousness at speeds that neither permit nor require evaluation. (70)
