What are examples of juxtaposition in poetry?
The Japanese haiku (as distinct from non-Japanese variations on the Japanese philosophy of haiku) embodies juxtaposition of nature with human activity with the objective of revealing something about human nature. Juxtaposition can be defined as the arrangement of two or more concepts next to each other to produce a strong affect. Revealing something about human nature by arranging nature and human activity produces just such a strong affect. Sonnets also employ juxtaposition. For instance, Shakespeare's Sonnet 29 juxtaposes misery and envy with lark's songs to reveal something about the nature of love.
