All _Pain_ and _Uneasiness_ proceeds at first from and is caus'd by Somewhat without and distinct from the Mind itself. The Soul must first be acted upon before it can re-act. In the Beginning of Infancy it is as if it were not; it is not conscious of its own Existence, till it has receiv'd the first Sensation of _Pain_; then, and not before, it begins to feel itself, is rous'd, and put into Action; then it discovers its Powers and Faculties, and exerts them to expel the Uneasiness. Thus is the Machine set on work; this is Life. We are first mov'd by _Pain_, and the whole succeeding Course of our Lives is but one continu'd Series of Action with a View to be freed from it. As fast as we have excluded one Uneasiness another appears, otherwise the Motion would cease. If a continual Weight is not apply'd, the Clock will stop. And as soon as the Avenues of Uneasiness to the Soul are choak'd up or cut off, we are dead, we think and act no more. II. _This Uneasiness, whenever felt, produces_ Desire _to be freed from it, great in exact proportion to the Uneasiness._ Thus is _Uneasiness_ the first Spring and Cause of all Action; for till we are uneasy in Rest, we can have no Desire to move, and without Desire of moving there can be no voluntary Motion. The Experience of every Man who has observ'd his own Actions will evince the Truth of this; and I think nothing need be said to prove that the _Desire_ will be equal to the _Uneasiness_, for the very Thing implies as much: It is not _Uneasiness_ unless we desire to be freed from it, nor a great _Uneasiness_ unless the consequent Desire is great. I might here observe, how necessary a Thing in the Order and Design of the Universe this _Pain_ or _Uneasiness_ is, and how beautiful in its Place! Let us but suppose it just now banish'd the World entirely, and consider the Consequence of it: All the Animal Creation would immediately stand stock still, exactly in the Posture they were in the Moment Uneasiness departed; not a Limb, not a Finger would henceforth move; we should all be reduc'd to the Condition of Statues, dull and unactive: Here I should continue to sit motionless with the Pen in my Hand thus------and neither leave my Seat nor write one Letter more. This may appear odd at first View, but a little Consideration will make it evident; for 'tis impossible to assign any other Cause for the voluntary Motion of an Animal than its _uneasiness_ in Rest. What a different Appearance then would the Face of Nature make, without it! How necessary is it! And how unlikely that the Inhabitants of the World ever were, or that the Creator ever design'd they should be, exempt from it!
