Walter J. Ong quotes:

Learners are doers, not recipients.

Print encourages a sense of closure, a sense that what is found in a text has been finalized, has reached a state of completion.

For the way in which the word is experienced is always momentous

There is no way to write unless you read, and read a lot.

Without writing, the literate mind would not and could not think as it does, not only when engaged in writing but normally even when it is composing its thoughts in oral form. More than any other single invention writing has transformed human consciousness.
