RARE FIRST EDITION of this attempt at reconciling religion and science and establishing an understanding of the Milky Way. A book of considerable importance in the history of science. Wright first explained the Milky Way and the nebulae as external galaxies and provided the basis for the theories on the universe by Kant, Herschel and Laplace (see Paneth for a detailed discussion of the connection between Wright and Kant).
Wright, a teacher of navigation and a land surveyor by profession, "hypothesized a 'divine center' of the universe, corresponding to a gravitational center around which the sun and other stars orbited. He also proposed, as a possible explanation for the visual phenomenon of the Milky Way, a model of the universe in which the orbiting stars formed a flattened ring, this hypothesis caused Immanuel Kant, who did not realize that Wright's 'center' was supernatural, to credit Wright with originating a disk-shaped model of the galaxy" (Norman).
"The title [of Wright's book] already indicates that here he is aiming much higher: an original theory or new hypothesis of the Universe, solving particularly the phenomenon of the Milky Way. Let us state at the outset that this claim is not at all exaggerated. For the first time in the history of astronomy the view is expressed here that the fixed stars are not distributed at random in space, but mainly concentrated in a flat disk; that the Sun with his planets is situated somewhere not too far from the disk's centre, and that, therefore, for us many more stars are visible in the direction of the disk's plane than in any other. As they are too numerous to be seen separately they appear to the naked eye as a luminous circle on the sky - the Milky Way. The explanation given here by Wright of the galaxy as an optical phenomenon, following from, and thus revealing, a disk-like distribution of the visible stars, is contained in the seventh letter, and illustrated by a diagram. The wording of the crucial paragraph is rather clumsy and involved, and the author at once proceeds to much wilder speculations in which the Universe appears as a combination of concentric shells ; the Eye of Providence is seated in the Centre and becomes, therefore, clearly visible on the plate depicting the Universe in cross section. It was, perhaps, a blessing in disguise that the very careful abstractor who reviewed the book for a Hamburg periodical, the Freys Urtheile und Nachrichten zum Aufnehmen der Wissenschaften und der Historie überhaupt (Year 8, Part I, Jan. 1, 1751) was, to his regret, unable to include the copper plate prints and had consequently to omit these passages which could not be presented without reference to the diagrams. Wright's convincing explanation of the nature of the galaxy stands out all the clearer in the translator's account. It was this summary which Kant happened to read, and which became the starting point of his own cosmological speculations" (Paneth, pp. 74-75).
*The engraved portrait frontispiece is not called for in this work, but is part of Wright's earlier work Clavis coelestis (London, 1742).
