Crane suffered from bouts of depression, and saw his poetry as
an attempt to combat what he saw as a debased, materialistic world;
further, his career had various ups and downs, he had troubled
relations with his family, and deep ambivalence about his
sexuality. As for a specific precipitating event, there is some
speculation about his having made a spurned advance toward a crew
member on Orizaba (the ship he jumped from), though without some
word from him, no one knows for sure.
