"... motion without a motive force, and an effect without a cause are both impossible ..."

"In fine, that Universal Reality with all its qualities and attributes that we recount is holy and exalted above all minds and understandings. As we, however, reflect with broad minds upon this infinite universe, we observe that motion without a motive force, and an effect without a cause are both impossible; that every being hath come to exist under numerous influences and continually undergoeth reaction. These influences, too, are formed under the action of still other influences. ..."
