         in a state of nature as contradistinguished from

   Note: In this sense God is called the Absolute by the Theist.
         The term is also applied by the Pantheist to the
         universe, or the total of all existence, as only
         capable of relations in its parts to each other and to
         the whole, and as dependent for its existence and its
         phenomena on its mutually depending forces and their
         laws.

   5. Capable of being thought or conceived by itself alone;
      unconditioned; non-relative.

   Note: It is in dispute among philosopher whether the term, in
         this sense, is not applied to a mere logical fiction or
         abstraction, or whether the absolute, as thus defined,
         can be known, as a reality, by the human intellect.

               To Cusa we can indeed articulately trace, word
               and thing, the recent philosophy of the absolute.

      the sentence in government; as, the case absolute. See
      {Ablative absolute}, under {Ablative}.

   {Absolute curvature} (Geom.), that curvature of a curve of
      double curvature, which is measured in the osculating
      plane of the curve.

      eccentric equations.

   {Absolute space} (Physics), space considered without relation
      to material limits or objects.

   {Absolute terms}. (Alg.), such as are known, or which do not
      contain the unknown quantity. --Davies & Peck.

   {Absolute temperature} (Physics), the temperature as measured
      on a scale determined by certain general thermo-dynamic
      principles, and reckoned from the absolute zero.

   1. The act of curving, or the state of being bent or curved;
