But of things impossible, which we think possible, we may Deliberate; not knowing it is in vain.

And it is called DELIBERATION; because it is a putting an end to the Liberty we had of doing, or omitting, according to our own Appetite, or Aversion.
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.
The Will 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.
