universe + ??? to place or arrange.] (Metaph.)
Assuming or positing the actual existence or reality of the
physical or external world.
{Cosmothetic idealists} (Metaph.), those who assume, without
   attempting to prove, the reality of external objects as
   corresponding to, and being the ground of, the ideas of
   which only the mind has direct cognizance.
         The cosmothetic idealists . . . deny that mind is
         immediately conscious of matter.      --Sir W.
