42. All desire happiness.
If it be further asked,--What it is moves desire? I answer,--happiness, and that alone.
Happiness and misery are the names of two extremes, the utmost bounds whereof we know not; it is what "eye
hath not seen, ear hath not heard, nor hath it entered into the heart of man to conceive." But of some degrees of
both we have very lively impressions; made by several instances of delight and joy on the one side, and torment
and sorrow on the other; which, for shortness' sake, I shall comprehend under the names of pleasure and pain;
there being pleasure and pain of the mind as well as the body,-"With him is fulness of joy, and pleasure for
evermore." Or, to speak truly, they are all of the mind; though some have their rise in the mind from thought,
others in the body from certain modifications of motion.
