Samuel Butler, Erewhon — Chapter 22: The Colleges of Unreason… (1872)
“ If a man gets to know more than his neighbours he should keep his knowledge to himself till he has sounded them, and seen whether they agree, or are likely to agree with him. He said it was as immoral to be too far in front of one's own age, as to lag too far behind it. If a man can carry his neighbours with him, he may say what he likes; but if not, what insult can be more gratuitous than the telling them what they do not want to know? A man should remember that intellectual over-indulgence is one of the most insidious and disgraceful forms that excess can take. ”
