"An Original Theory or New Hypothesis of the Universe" by Thomas Wright is a scientific publication likely written in the mid-18th century. The work consists of a series of letters presented to a friend, where Wright attempts to articulate a coherent theory of the universe, particularly focusing on the phenomena of the Milky Way, using mathematical principles and observations from nature. The book also engages in a broader philosophical discourse on the nature of the universe and humanity's understanding of it. The opening of the text sets the stage for Wright's ambitious exploration of the cosmos. He expresses an awareness of the challenges that come with presenting new theories, particularly in astronomy, a field marked by historical ridicule of avant-garde ideas. Through a combination of personal reflection and references to esteemed predecessors, he lays out his intentions to delve into the nature and motion of planets, touching on mathematical certainty and moral probability related to conjectures about the universe. Wright underscores the importance of wonder in the pursuit of knowledge, suggesting that mankind's understanding of divine creation is intrinsically tied to astronomical inquiry.
