naturally delighted in variety. Also, by the Rational Repetitions, the Mind is either delighted, or displeased; and sometimes, partly pleased, and partly displeased: for, the Mind is as much pleased, or displeased in the absence of an Object, as in the presence; only the Pleasure, and Displeasure of the Senses, is not joyned with the Rational: for, the Sense, if Regular, makes the most perfect Copies when the Object is present: but, the Rational can make as perfect Copies in the absence, as in the presence of the Object; which is the cause that the Mind is as much delighted, or grieved, in the absence of an Object, as with the presence: As for example, A Man is as much grieved when he knows his Friend is wounded, or dead, as if he had seen his Wounds, or had seen him dead: for, the Picture of the dead Friend, is in the mind of the living Friend; and if the dead Friend was before his Eyes, he could but have his Picture in his mind; which is the same for an absent Friend alive; only, as I said, there is wanting the Sensitive Perception of the absent Object: And certainly, the Parts of the Mind have greater advantage than the Sensitive Parts; for, the Mind can enjoy that which is not subject to the Sense; as those things Man names, _Castles in the Air_, or _Poetical Fancies_; which is the reason Man can enjoy Worlds of its own making, without the assistance of the Sensitive Parts; and can govern and command those Worlds; as also, dissolve and compose several Worlds, as he pleases: but certainly, as the pleasures of the Rational Parts are beyond those of the Sensitive, so are their Troubles.
