This project explores the intersection of literature and science from the mid-eighteenth century to the mid-nineteenth century in the context of this shift in conceptions of space and time. Confronted with the rapid and immense expansion of space and time, eighteenth and nineteenth-century philosophers and authors sought to locate humans' relative position in the vast void. Furthermore, their attempts to spatially and temporally map the universe led to changes in perceptions of the relationship between the exterior world and the interior self. In this dissertation I focus on a few important textual monuments that serve as landmarks on this journey. During the eighteenth and nineteenth centuries, the intersection of literary and scientific texts transformed perceptions of space and time. These transformations then led to further advancements in the way scientific knowledge was articulated. Imagination became central to scientific writing at the same time it came to dominate literary writing. My project explores these intersecting influences among literature, astronomy, cosmology, and geology, on the perceptions of expanding space and time.
