Final answer:
Emily Dickinson gradually isolated herself from social life over time, with the reclusive period often highlighted as starting around her most prolific years of 1861-1865. Her seclusion was a personal choice rather than a singular event, and her works reflect deep engagement with life.
Step-by-step explanation:
The period when Emily Dickinson began to isolate herself from her social life is not specifically documented with a precise date. Dickinson was born into a socially prominent family in 1830 and received a substantial education. Despite this, she later chose a path that led her to live a reclusive life.
Her life of seclusion is often emphasized in discussions and analyses of both her personality and her poetry. It's important to note that her solitary life did not prevent her from forging a profound connection with the world through her literary works, which continue to be celebrated for their technical complexity and innovative perspective.
Emily Dickinson's poetry, particularly from her most prolific years between 1861-1865, reflects her mastery of the lyric form. Even as she led a reclusive life, her vibrant language and celebrated individual will showed that she engaged fully with life through her literary creations. Dickinson's life of seclusion developed over time and was not the result of a single event, but a personal choice possibly rooted in her nature and experiences.
