There are two great pitfalls, two great scourges, the Scylla and Charybdis of contemporary poetry. On the one hand, talking down to the general reader (through condescension, facile suavity, or flattery). On the other hand, talking only to fellow poets (the coteries, the cults, the academies). Both of these extremes are, basically, shortcomings of style, and both have a powerful deleterious effect on the general literary climate.
Good poetry somehow discovers the middle path (through the Gates of Wrath).
