Ubiety (Lat. ubi, "where") is the presence of one thing to another, or the presence of a thing in place. The schoolmen distinguish ubiety as:
1. Circumscriptive, by which a body is so in one place that its parts are answerable to the parts of space in which it is and exclude every other body.
2. Definitive, as when a human spirit is limited or defined in its presence to the same place, like a human body.
3. Repletive, as when the Infinite. Spirit is present through every portion of space.
This last is sometimes called UBIQUITY SEE UBIQUITY (q.v.), and means the Divine Omnipresence. See Krauth, Vocab. of Phil. Sciences, s.v.
