Ezra Pound has been fathered with vers libre in English, with all its vices and virtues. The term is a loose one--any verse is called "free" by people whose ears are not accustomed to it--in the second place, Pound's use of this medium has shown the temperance of the artist, and his belief in it as a vehicle is not that of the fanatic. He has said himself that when one has the proper material for a sonnet, one should use the sonnet form; but that it happens very rarely to any poet to find himself in possession of just the block of stuff which can perfectly be modelled into the sonnet. It is true that up to very recently it was impossible to get free verse printed in any periodical except those in which Pound had influence; and that now it is possible to print free verse (second, third, or tenth-rate) in almost any American magazine. Who is responsible for the bad free verse is a question of no importance, inasmuch as its authors would have written bad verse in any form; Pound has at least the right to be judged by the success or failure of his own. Pound's vers libre is such as is only possible for a poet who has worked tirelessly with rigid forms and different systems of metric.
***The freedom of Pound's verse is rather a state of tension due to constant opposition between free and strict. There are not, as a matter of fact, two kinds of verse, the strict and the free; there is only a mastery which comes of being so well trained that form is an instinct and can be adapted to the particular purpose in hand.
