Desire accompanies all uneasiness.       §39. I have hitherto chiefly instanced in the uneasiness of desire,
as that which determines the will. Because that is the chief, and
most sensible; and the will seldom orders any action, nor is there
any voluntary action performed, without some desire accompanying
— 257 —
it; which I think is the reason why the will and desire are so often
confounded. But yet we are not to look upon the uneasiness which
makes up, or at least accompanies most of the other Passions, as
wholly excluded in the case. Aversion, Fear, Anger, Envy, Shame, etc.
have each their uneasiness too, and thereby influence the will. These
Passions are scarce any of them in life and practice, simple, and
alone, and wholly unmixed with others; though usually in discourse
and contemplation, that carries the name, which operates strongest,
and appears most in the present state of the mind. Nay there is, I
think, scarce any of the Passions to be found without desire join’d
with it. I am sure, where-ever there is uneasiness there is desire: For
we constantly desire happiness; and whatever we feel of uneasiness,
so much, ’tis certain, we want of happiness; even in our own
Opinion, let our state and condition otherwise be what it will.
Besides, the present moment not being our eternity, whatever our
enjoyment be, we look beyond the present, and desire goes with
our foresight, and that still carries the will with it. So that even in
joy it self, that which keeps up the action, whereon the enjoyment
depends, is the desire to continue it, and fear to lose it: And when-
ever a greater uneasiness than that takes place in the mind, the will
presently is by that determin’d to some new action, and the present
delight neglected.
