No humane being, past the thoughtless age of boyhood, will wantonly murder any creature which holds its life by the same tenure that he does.
—Henry David Thoreau
sonnet
A 14-line lyric poem that often explores and resolves a focused theme. Italian (or Petrarchan) sonnets are divided into two quatrains and a six-line "sestet"; English (or Shakespearean) sonnets are composed of three quatrains and a final couplet. English sonnets are written generally in iambic pentameter.
