First, Modes I call such complex Ideas, which however compounded, contain not in them the supposition of subsisting by themselves, but are considered as Dependences on, or Affections of Substances; such are the Ideas signified by the words Triangle, Gratitude, Murther, &c. and if in this I use the word Mode, in somewhat a different sense from its ordinary signification, I beg pardon; it being unavoidable in Discourses, differing from the ordinary received Notions, either to make new Words, or to use old Words in somewhat a new signification; which in our present case, is perhaps the more tolerable of the two.
