Consider some of the qualities of typical modernistic poetry: very interesting language, a great emphasis on connotation, "texture"; extreme intensity, forced emotion — violence; a good deal of obscurity; emphasis on sensation, perceptual nuances; emphasis on details, on the part rather than on the whole; experimental or novel qualities of some sort; a tendency toward external formlessness and internal disorganization — these are justified, generally, as the disorganization required to express a disorganized age, or, alternatively, as newly discovered and more complex types of organization; an extremely personal style — ; lack of restraint — all tendencies are forced to their limits; there is a good deal of emphasis on the unconscious, dream structure, the thoroughly subjective; the poet's attitudes are usually anti-scientific, anti-common-sense, anti-public — he is, essentially, removed; poetry is primarily lyric, intensive — the few long poems are aggregations of lyric details; poems usually have, not a logical, but the more or less associational style of dramatic monologue; and so on and so on. This complex of qualities is essentially romantic; and the poetry that exhibits it represents the culminating point of romanticism.
