But if we allow theſe Planetary Inhabitants ſome ſort of Reaſon, muſt it needs, may ſome ſay, be the ſame with ours? Certainly it muſt, whether we conſider it as applied to Juſtice and Morality, or exerciſed in the Principles and Foundations of Science. For Reaſon with us is that which gives us a true Senſe of Juſtice and Honeſty, Praiſe, Kindneſs and Gratitude: ’tis That that teaches us to diſtinguiſh univerſally between Good and Bad; and renders us capable of Knowledge and Experience in it. And can there be any where any other Sort of Reaſon than this? or can what we call juſt and generous, in Jupiter or Mars be thought unjuſt Villany? This is not at all, I don’t ſay probable, but poſſible. For the Aim and Deſign of the Creator is every where the Preſervation and Safety of his Creatures. Now when ſuch Reaſon as we are Maſters of, is neceſſary for the preſervation of Life, and promoting of Society (a thing that they are not without, as we ſhall ſhow) would it not be ſtrange that the Planetary Inhabitants ſhould have ſuch a perverſe Sort of Reaſon given them, as would neceſſarily deſtroy and confound what it was deſign’d to maintain and defend? But allowing Morality and Paſſions with thoſe diſtant Inhabitants to be ſomewhat different from ours, and ſuppoſing they may act by other Principles in what belongs to Friendſhip and Anger, Hatred, Honeſty, Modeſty, and Comelineſs, yet ſtill there would be no doubt, but that in the Search after Truth, in judging of the Conſequences of Things, in Reaſoning, particularly in that Sort which belongs to Magnitude or Quantity, about which their Geometry (if they have ſuch a Thing) is employ’d, there would be no doubt, I ſay, but that their Reaſon here muſt be exactly the ſame, and go the ſame way to work with ours, and that what’s true in one part will hold true over the whole Univerſe; ſo that all the difference muſt lie in the Degrees of Knowledge, which will be proportional to the Genius and Capacity of the Inhabitants.
