Neoclassical

poetry as expression
poetry as mimesis (representation of the world)
poetry is organic; grows from seed of idea into integral whole
poetry is crafted; forms are derived from ancient models
lyric poetry is central
narrative or didactic poetry and mock forms central
lyric speaker has traits of author
speaker is a persona even when speaking in the author's name
poet is "chosen son" or Bard who will redeem humanity
poet is ordinary person with unusual wit and learning who should know his place
poetry is spontaneous
poetry is craft
common language
varied meters and rhyme schemes
avoidance of "artificial" personifications and poetic diction
language should be carefully crafted and appropriate to genre (decorum)
heroic couplets or tetrameter couplets dominant
poetic diction
personifications

nature is primary poetic subject
nature = natural landscape
close observation important

poetry generally urban in sensibility
nature = what is unchangingly true
general more important than particular, so observation, while important, has a different meaning
poems endow landscape with human qualities; landscape is living entity participating in feelings of observer
poetry elevates outcasts, ordinary folk, rural poor, the insane, etc.
decorum: highest genres and most serious treatment reserved for highest classes
imagination, wonder are vital
wonder, Fancy associated with credulity, naiveté
the supernatural a legitimate poetic subject; interest in unusual modes and realms of experience such as dreams, visions, the forbidden, etc.

the supernatural (as opposed to the genuinely religious) is nonsense or mere poetic convention; reason is primary
