Excerpt from An Introduction to Logic Propositions, and the inferences themselves are always Propositions. Hence it is absolutely necessary for a Logician to consider the meaning or import of a Pro position. Indeed it will be seen hereafter that before we can lay down rules for drawing or testing inferences, it is necessary to reduce all Propositions to a fixed number of stated forms. Every Proposition, too, must contain at least two terms and a copula, and therefore Terms must also be dealt with in a Treatise on Logic.
