“No matter what the legislature may say, a man has the right to make his speech, print his handbill, compose his newspaper, and deliver his sermon without asking anyone's permission. The contrary suggestion is abhorrent to our traditions.”

Originally delivered as a lecture (late 1927); Pure Poetry: Notes for a Lecture The Creative Vision (1960)
Context: For the musician, before he has begun his work, all is in readiness so that the operation of his creative spirit may find, right from the start, the appropriate matter and means, without any possibility of error. He will not have to make this matter and means submit to any modification; he need only assemble elements which are clearly defined and ready-made. But in how different a situation is the poet! Before him is ordinary language, this aggregate of means which are not suited to his purpose, not made for him. There have not been physicians to determine the relationships of these means for him; there have not been constructors of scales; no diapason, no metronome, no certitude of this kind. He has nothing but the coarse instrument of the dictionary and the grammar. Moreover, he must address himself not to a special and unique sense like hearing, which the musician bends to his will, and which is, besides, the organ par excellence of expectation and attention; but rather to a general and diffused expectation, and he does so through a language which is a very odd mixture of incoherent stimuli.

Investigations have failed to confirm this in Emerson's writings (John H. Lienhard. "A better moustrap" http://www.uh.edu/engines/epi1163.htm, Engines of our Ingenuity). Also reported as a misattribution in Paul F. Boller, Jr., and John George, They Never Said It: A Book of Fake Quotes, Misquotes, & Misleading Attributions (1989), p. 25. Note that Emerson did say, as noted above, "I trust a good deal to common fame, as we all must. If a man has good corn, or wood, or boards, or pigs, to sell, or can make better chairs or knives, crucibles or church organs, than anybody else, you will find a broad hard-beaten road to his house, though it be in the woods".
