Samuel Taylor Coleridge (1772-1834) was an English poet, critic, and philosopher who was, along with his friend William Wordsworth, one of the founders of the Romantic Movement in England and one of the Lake Poets. He is probably best known for his poems The Rime of the Ancient Mariner and Kubla Khan, as well as his major prose work Biographia Literaria.
Nature might be an amplifier of happy emotions, but humans truly feel happy only ehen psychologically, from within, they're happy first. Moving wonders of nature although are happy sights, they would trivial and meaningless who can't find joy in their hearts. A worse condition than being sad, is having no feeling at all. That's what Coleridge's feeling dejected about, his inability to feel, his loosing poetic talent and inspiration, his opium addiction, his unattainable lover.
Beautiful poem.
And now is almost grown the habit of my soul [to remain stoic]
