Goethe fell in love with several women during his lifetime. During the early period of his life, he was in love with a girl named Friederike Brion, the daughter of a pastor. Several of his poems are inspired by her. He felt extremely sad when they split up. The feeling of desertion by a lover is found in a lot of Goethe’s works. They are all based on his own experience. His disappointment in love inspired him when writing about Werther in "Die Leiden des jungen Werthers" and Gretchen in his great play "Faust". His poems also show his ideas about science and philosophy.
