"The reciprocal relations of Space, Time, and God, are veiled in impenetrable darkness. Many minds hesitate to attribute real infinity to Space and Time, lest it should conflict with the infinity of God. Such timidity has but a slender title to respect. If the Laws of Thought necessitate any conclusion whatever, they necessitate the conclusion that Space and Time are each infinite; and if we cannot reconcile this result with the infinity of God, there is no alternative but to accept of scepticism with as good a grace as possible. No man is worthy to join in the search for truth, who trembles at the sight of it when found. But a profound faith in the unity of all truth destroys scepticism by anticipation, and prophesies the solutions of reason. Space is infinite, Time is infinite, God is infinite; three infinites coexist. Limitation is possible only between existences of the same kind. There could not be two infinite Spaces, two infinite Times, or two infinite Gods; but while infinites of the same kind cannot coexist, infinites of unlike kinds may. When an hour limits a rod, infinite Time will limit infinite Space; when a year and an acre limit wisdom, holiness, and love, infinite Space and Time will limit the infinite God. _But not before._ Time exists ubiquitously, Space exists eternally, God exists ubiquitously and eternally. The nature of the relations between the three infinites, so long as Space and Time are ontologically incognizable, is utterly and absolutely incomprehensible; but to assume contradiction, exclusion, or mutual limitation to be among these relations, is as gratuitous as it is irreverent."
