This alternate succession of Appetites, Aversions, Hopes and Feares is no less in other living Creatures than in Man; and therefore Beasts also Deliberate.
Every Deliberation is then sayd to End when that whereof they Deliberate, is either done, or thought impossible; because till then wee retain the liberty of doing, or omitting, according to our Appetite, or Aversion.
In Deliberation, the last Appetite, or Aversion, immediately adhaering to the action, or to the omission thereof, is that wee call the WILL; the Act, (not the faculty,) of Willing. And Beasts that have Deliberation must necessarily also have Will. The Definition of the Will, given commonly by the Schooles, that it is a Rationall Appetite, is not good. For if it were, then could there be no Voluntary Act against Reason. For a Voluntary Act is that, which proceedeth from the Will, and no other. But if in stead of a Rationall Appetite, we shall say an Appetite resulting from a precedent Deliberation, then the Definition is the same that I have given here. Will, therefore, Is The Last Appetite In Deliberating. And though we say in common Discourse, a man had a Will once to do a thing, that neverthelesse he forbore to do; yet that is properly but an Inclination, which makes no Action Voluntary; because the action depends not of it, but of the last Inclination, or Appetite. For if the intervenient Appetites make any action Voluntary, then by the same reason all intervenient Aversions should make the same action Involuntary; and so one and the same action should be both Voluntary & Involuntary.
By this it is manifest, that not onely actions that have their beginning from Covetousness, Ambition, Lust, or other Appetites to the thing propounded; but also those that have their beginning from Aversion, or Feare of those consequences that follow the omission, are Voluntary Actions.
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.
