Rest

REST

(GR. μονή, ρεμία; Lat. quies, mansio, status ), the opposite of motion. It is the privation of motion in that which is receptive of motion but is not actually being moved. Rest in an initial state (terminus a quo ) is contrary to the motion that proceeds from it, but there is no strict contrariety between motion and rest in a terminating state (terminus ad quem ), since rest is the end and perfection of motion, the state of actuality to which motion tends. Likewise, motion is the cause of rest, and something is not the cause of its contrary. Motion and rest are in the same subject, although not both together.

There is a rest corresponding to each type of motion, so that a being may be in motion in one respect and simultaneously at rest in the possession of some state acquired by a different kind of motion. substantial change is not only absence of change.

Rest is measured by time, not by the indivisible now. Strictly speaking, only motion is measured by time, since time is the number of motion according to before and after. A body in the state of rest is a mobile being, and its repose has come about as the result of a motion and will cease when a contrary motion occurs. The duration of the repose between two such motions is measured by means of the duration of the motion of some other body.

Like motion, rest can be either natural and according to nature or unnatural and forced. Rest can be understood in an extended sense. When an agent ceases acting, it is said to come to rest. The mind rests in contemplation of truth and the appetites in the possession of good. The state of equilibrium is not so much rest as the balancing off of opposite forces. Homeostasis is a state of dynamic equilibrium that tends to maintain itself in living beings.

See Also: motion; reality.

Citation styles

Encyclopedia.com gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, Encyclopedia.com cannot guarantee each citation it generates. Therefore, it’s best to use Encyclopedia.com citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:

Notes:
  • Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most Encyclopedia.com content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
  • In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
