It should be distinct, and free from all perplexing Mixture of Things which ought to be kept separate, that so Confusion may be evited. (4.)

ONTOLOGY, or the Science
of Being abstračtedly consider’d.


NTOLOGY is a Science which ONTOLOGY
treats of Being or Entity, and its defined.
Properties; and that abstractedly
in its own simple Nature, and not
as it relates to Bodies and Forms,

which is the Business of Physics or
Natural Philosophy ; or to Quantity, which is of
a Mathematical Consideration ; but absolutely as
it relates to the Existence of all Things indif-
ferently. This Doctrine was formerly callid

Being, Entity, and Existence are all Syr:ony- Being, Entity, mous Words, and only signify the State of that and Existence, which is or doth exijt, purely as existing ; info- what. much that all particular Ideas, of Body, Form or Quality, are excluded, since Being is the absolute original State, and primary Property necessary to all of them.

But the same Words Being, Entity, Existence, The same ir a when used in a more restrain'd Sense, do also sig-resirain'd nify Things themselves which do exist, but then Senfe. it is simply and purely with regard to them as fucb, i. e, as Things existing only, without any Reference to Modes or Qualities inherent in them. As when we say, The Planets may

be inhabited by some Sort of Beings: The Fairies are not real buit imaginary Beings, &c. Tho' the Word



[ocr errors]

Beings is more commonly used than Entities, and Existence never in the Plural, and seldom

in the Singular to express the Thing existing. The Subje&t of In this Sense, Being or Entity is the Object Ontology. of this Science, which occafion'd'it to be call'd

Ontology by the Greeks, that Word with them importing the Do&trine of Beings abstractedly consider'd; and since the Notion of Being or Entity in the Abstract is the very Scul of this Science, it will be neceffary to explain in the next Place, what Abstračtion is, and what is meant by Being

in the Abstract. Abftraction ABSTRACTION, then, is that Faculty of what. the Mind, whereby we consider, and contem

plate the various Relations, Properties, and Qualities of Bodies, alone, or as they are in them. selves, and not as they are in the Bodies. By this Act of the Mind, we as it were separate and withdraw it from the Body and all other Modes and Relations, and view it in itself ; and thus (to speak with the Schools) we deduce a

Thing from a singular to an universal State. Ab1s of tivo straction is of two kinds, viz. Precisive and NeKinds. gative. Of Precipue

Precisive Abstraction is when we consider those Ábfiraction. Things apart, which cannot really exist apart ;

as when we consider a Mode or Property apart from the Subject, or one essential Mode without another. Thus I can consider that which we call white in a Wall, but in my Mind I can abstract this from its fingular State, in its Subject the Wall, and consider it in a more universal State, as a Quality which I call Whiteness ; and find it may be attributed to a great Variety of Subjects, as Milk, Snow, Chalk, Eggs, &c. Thus the round Shape of a Globe, I abstractedly consider as a Quality, and find it, as such, in several other Subjects, and of different

Kinds ; as the Roundness of a Circle, the Roundness of a Cylinder, &c. Also Whiteness and Roundness may be consider'd apart, not only from the Subjects the Wall and the Globe, but distinctly from all other Modes and Relntions belonging to them, as Height; Solidity, Weight, &c.

Negative Abstraction is when we consider one of Negative Thing separate from another, which may also Abftraction. exist without it. As when we conceive of a Subject without regarding its accidental Modes and Relations; or when we conceive of one Acci. dent without thinking of another. As when I conceive the Idea of a Needle, without the Idea of its Sharpness, it is a Negative Abstraction ;, and it is the same when I think of a Book, without the Idea of Reading or Writing; or when I think of reading without considering the Manner, whether Vocally or Mentally.

THINGS thus conceived of, or represented When Things apart from the Subject, in the Manner as above are said to be described, are said to be in the Abstract ; but

in the Abstract

or Concrete. when they are particularly consider'd with or inherent in their Subjects, they are then said to be consider'd in the Concrete or Subject. Or thus, we say, white, round, toll

, witty, weighty, lively, dead, mortal, &c. in the Concrete ; but, in the Abstract, we say, Whiteness, Roundness, Tallness, Wittiness, Weightiness, Liveliness, Deadness, Mertality, &c.

Having thus distinguish'd or specified the Manner of Conception of Being or Existence in our Minds; I shall next enumerate the kinds of Being, and then the peculiar Properties belonging thereto, and which distinguish them from one another.

I think all Being in the Universe may be di- of the Kinds stributed into two General Kirds, viz. (1.) Ma

of Being, fube

ftantial and Q3

terial modal.
