In the poetry of Alan Ginsburg, Ginsburg often used the poetic style of long-line free verse in order to write in a poetic manner that allowed him to express his thoughts and emotions in an open and honest manner that was not constrained by the relatively strict rules of formal, carefully structured poetry. Ginsberg attempted, in his poetry, to convey the actual processes of human emotion in a natural, chaotic, and realistic style that mirrored the ways in which people truly think and feel.
