It’s not that I think children should be seen and not heard. Why stop at children? How many adults generate utterances equivalent to the paragraph of Spinoza one could have read in the time taken up by the utterance? Chances are the utterances of Spinoza himself would not have achieved equivalence, because I can read 900 words a minute and it is unlikely that Spinoza could speak at that speed, let alone speak at that speed while maintaining the level of excellence of his writing.
