Final answer:
Coleridge studied the mystical writings of Jakob Boehme and the philosophy of Immanuel Kant during his 1798 trip to Germany with the Wordsworths, reflecting the quintessential Romantic engagement with the sublime nature and individual imagination.
Step-by-step explanation:
In 1798, Samuel Taylor Coleridge traveled with William and Dorothy Wordsworth to Germany, where he immersed himself in the mystical writings of Jakob Boehme and the philosophy of Immanuel Kant. Coleridge's interest in Boehme's works reflects the Romantic era's fascination with the mystical and sublime aspects of nature, aligning with the period's broader literary themes of natural beauty and emotional depth. Kant's influence, on the other hand, contributed to Coleridge's engagement with ideas of individual freedom and imagination, which were central to Romantic thought and artistry.
