"Since the Sun and fix'd Stars, says Dr. _Gregory_, are the only great Bodies of the Universe that have any native Light, they are justly esteemed by Philosophers to be of the same Kind, and designed for the same Uses; and it is the Effect of a Man's Temper that sets a greater Value upon his own Things than he ought, that makes him judge the Sun to be the biggest of them all." That, as an elegant[F] Writer observes, which we call the Morning, or the Evening Star, is, in reality, a _Planetary World_; which, with the four others, that so wonderfully, as _Milton_ expresses it, "vary their mystick Dance, are in themselves dark Bodies, and shine only by Reflection; have Fields and Seas, and Skies of their own; are furnished with all Accommodations for animal Subsistence, and are supposed to be the Abodes of intellectual Life. Again, The Sun, with all its attendant Planets is but a very little Part of the grand Machine of the Universe. Every Star--is really a vast Globe, like the Sun, in Size and in Glory, no less spacious, no less luminous, than the radiant Source of our Day; so that every Star is the Center of a magnificent System, has a Retinue of Worlds irradiated by its Beams, and revolves round its active Influence; all which are lost to our Sight in immeasurable Tracts of Æther. [Footnote F: Contemplations on the starry Heavens.] "Could we, says the same Author, wing our Way to the highest apparent Star--we should there see other Skies expanded, other Suns, that distribute their inexhaustible Beams of Day; other Stars, that gild the alternate Night; and other perhaps nobler Systems established; established in unknown Profusion, through the boundless Dimensions of Space. Nor does the Dominion of the great Sovereign end _there_, even at the End of this vast Tour, we should find ourselves advanced no farther than the Frontiers of Creation; arrived only at the Suburbs of the great _Jehovah's_ Kingdom." O for a Telescope his Throne to reach! Tell me ye Learn'd on Earth! or Blest above! Ye searching, ye _Newtonian_ Angels! tell, Where your great Masters Orb? His Planets where? Those conscious Satellites, those Morning Stars, First-born of _Deity_ from central Love. Dr. Young. Many other Authorities might be produced from Writers of great Repute, were it necessary to trouble you with them[G]; but I believe those above will be abundantly sufficient for the present Purpose, if even an Apology were wanting for my own Conjectures. I shall therefore conclude this Letter with the following Passage out of _Pope's Universal Prayer_, and in my next shall proceed in the Work I have undertaken. Yet not to Earth's contracted Span, Thy Goodness let me bound; Or think thee Lord alone of Man, When thousand Worlds are round. _I am_, &c.
