in a more general sense, a term synonymous with compound; though in strictness of speech there is some difference.

Complex is properly applied where a thing contains divers others, or consists of divers parts not really distinct from each other, but only imaginarily, or in Complex, our conceptions. In this sense the soul may be said to be complex, in respect of the understanding and will, which are two things that our reason alone distinguishes in it.

COMPLEX Term or Idea, is a term compounded of several simple or incomplex ones. Thus in the proposition, A just God cannot leave crimes unpunished; the subject of this proposition, viz. a just God, is a complex term, or stands for a complex idea composed of two simple or incomplex ones, viz. God and just.
