The conditions essential to a constructive mind do not appear to be so often combined but that a good sentence or verse remains fresh and memorable for a long time. Yet when we write with ease, and come out into the free air of thought, we seem to be assured that nothing is easier to continue this communication at pleasure. Up, down, around the kingdom of thought has no inclosures, but the Muse makes use free of her city. ... The intellect is a whole and demand integrity in every work. This is resisted equally by a man's devotion to a single thought, and by his ambition to combine too many.
How wearisome the grammarian, the phrenologist, the political or religious fanatic, or indeed any possessed mortal whose balance is lost by the exaggeration of a single topic. ... It is incipient insanity. Every thought is a prison also. I cannot see what you see because I am caught up by a strong wind, and blown so far in one direction that I am out of the hoop of your horizon.
From Intellect, Essays, First Series, by Ralph Waldo Emerson
In just a few paragraphs, Emerson goes from the wonders of communication to how necessary it is to take immediate advantage of a particular state of mind to capture the truth of whatever was beheld. The longevity of that communication relies on its ability to be retained in another mind for some period as to gestate.
Later in the essay, he talks about how a person should not be afraid to wrestle with a new doctrine that seems to be in contradiction or a "subversion of all of our opinions, tastes and manner of living." He suggests that we wrestle with the new doctrines and that somehow, after you have mastered the intent or value it won't be as frightening - indeed, may be added to your though arsenal. It will
No longer be an alarming meteor, but one more bright star shining serenely in your heaven, blending its light with all your day.
He acknowledges that concentration on a single subject runs the risk of fanaticism. He calls it "worrisome" to the point of "incipient insanity" whereby each thought becomes a prison.
I am caught up by a strong wind, and blown so far in one direction that I am out of the hoop of your horizon.
This can be be somewhat understood in the the current political climate where the winds are blowing people in seemingly two different directions - and those have been so blown in one or the other, that not only are people not within a "hoop of vision" you may not even be aware that there is another point of view so dedicated to one thought.
No more strong winds allowed.
