Ralph Waldo Emerson on ideas

What is the scholar, what is the man for, but for hospitality to every new thought of his time?  Have you leisure, power, property, friends? you shall be the asylum and patron of every new thought, every unproven opinion, every untried project, which proceeds out of good will and honest seeking.  All the newspapers, all the tongues of to-day will of course at first defame what is noble; but you who hold not of to-day, not of the times, but of the Everlasting, are to stand for it: and the highest compliment, man ever receives from heaven, is the sending to him its disguised and discredited angels.

That is from Introductory Lecture on the Times.
