As a youth, Wordsworth was a political radical, though his ideas of democracy, liberty, and equality do not seem radical to us today, because they have been largely incorporated into our politics. Wordsworth happened to be in France during the French Revolution and came home deeply depressed and disillusioned, as he describes in his long autobiographical poem The Prelude. As a result, he turned to poetry as a way to spread his ideals of building a better, more humane world.
Wordsworth had very happy memories of summer holidays in the Lake District as a child, where he developed a deep love of nature. He believed that he found God in nature and believed that if other people could have similar experiences, it would transform their souls, bringing them closer to becoming the people God intended them to be. He felt that nature was a solace, a source of peace, and a way to connection with the divine source that would cure people of seeking money and power.
Wordsworth also had a deep admiration for the poor people he met in the Lake District. He wanted to hold up their simple lives as models of purity and happiness. This seems a commonplace attitude now, but at the time it worked against the ordinary depictions of rural commoners as comic buffoons.
Wordsworth's poetics support his concerns for politics and the human condition. He believed that if people could develop a store of good memories from communing with nature, this would divert them from dissatisfaction and greed. He demonstrates this in his poems. His poetics also emphasize lyricism or emotion because he believed feeling could soften and transform the human heart, which in turn would change society.
