The quest to discover a definition for “literature” is a road that is much travelled, though the point of arrival, if ever reached, is seldom satisfactory. Most attempted definitions are broad and vague, and they inevitably change over time. In fact, the only thing that is certain about defining literature is that the definition will change. Concepts of what is literature change over time as well. What may be considered ordinary and not worthy of comment in one time period may be considered literary genius in another. Initial reviews of Emily Brontë's Wuthering Heights in 1847 were less than spectacular, however, Wuthering Heights is now considered one of the greatest literary achievements of all time. The same can be said for Herman Melville's Moby-Dick (1851).
