Organic Unity What is Organic Unity? The concept that every single element in a text (symbols, plot, tone, character actions) plays a unique role, yet none can function alone—every element is essential to the overall meaning and structure of the work. Contextual Analysis What is Contextual Analysis? Background information surrounding a literary work that helps readers understand it more deeply and recognize the values behind it. * Historical Context: Historical events, movements, and societal conditions influencing the story's era. * Example: Reading a story set during World War II to understand why food rationing occurs in the plot. * Cultural Context: Shared beliefs, customs, values, and traditions shaping character choices and themes. * Example: Analyzing family traditions and societal expectations in a story set in ancient Asia. * Biographical Context: How the author's real-life experiences and personal background impact their writing. * Example: Knowing Edgar Allan Poe experienced loss helps explain the grief themes in his poetry. * Psychological Context: Mental states, inner motivations, trauma, and psychological behaviors of characters or the author. * Example: Examining how traumatic events affect a main character's choices and fears. 3.

To Inform * Core Intent: Educate or share facts objectively without personal bias or subjective views. * Key Features: Textbooks, news reports, informational articles, research papers. To Entertain * Core Intent: Provide enjoyment, amusement, or engagement for the reader. * Key Techniques & Features: * Suspense: Creating anxiety or intense anticipation about what will happen next. * Example: "The footsteps grew louder on the wooden floorboards right outside her bedroom..." * Vivid Storytelling: Using rich sensory details so the reader can visualize the scene. * Example: "The crisp, icy wind whipped through the towering pine trees as the sun dipped below the crimson horizon." To Express Emotions * Core Intent: Share deeply personal, subjective experiences and inner feelings. * Key Features: Uses 1st Person POV ("I", "my"), personal journals, lyric poetry, and emotional reflections. To Explain / Analyze * Core Intent: Blend information with deeper critical insight to help readers thoroughly understand a complex topic. To Teach / Impart Values * Core Intent: Convey a moral lesson, ethical value, or clear guidance to the reader. * Key Features: Fables, parables, allegories, and didactic stories.
