The formes of Speech by which the Passions are expressed, are partly the same, and partly different from those, by which we express our Thoughts. And first generally all Passions may be expressed Indicatively; as, I Love, I Feare, I Joy, I Deliberate, I Will, I Command: but some of them have particular expressions by themselves, which nevertheless are not affirmations, unless it be when they serve to make other inferences, besides that of the Passion they proceed from. Deliberation is expressed Subjunctively; which is a speech proper to signifie suppositions, with their consequences; as, If This Be Done, Then This Will Follow; and differs not from the language of Reasoning, save that Reasoning is in generall words, but Deliberation for the most part is of Particulars. The language of Desire, and Aversion, is Imperative; as, Do This, Forbear That; which when the party is obliged to do, or forbear, is Command; otherwise Prayer; or els Counsell. The language of Vaine-Glory, of Indignation, Pitty and Revengefulness, Optative: but of the Desire to know, there is a peculiar expression called Interrogative; as, What Is It, When Shall It, How Is It Done, and Why So? Other language of the Passions I find none: for Cursing, Swearing, Reviling, and the like, do not signifie as Speech; but as the actions of a tongue accustomed.

These forms of Speech, I say, are expressions, or voluntary significations of our Passions: but certain signes they be not; because they may be used arbitrarily, whether they that use them, have such Passions or not. The best signes of Passions present, are either in the countenance, motions of the body, actions, and ends, or aims, which we otherwise know the man to have.
