COSMOTHETIC IDEALISTS.—An alternative designation applied by Hamilton to
Hypothetical Dualists,—a class which constitutes, he says, "the great majority
of modern philosophers. Denying our immediate or intuitive knowledge of the
external reality, whose existence they maintain, they, of course, hold a
doctrine of mediate or representative perception, and, according to the various
modifications of that doctrine, they are again subdivided into those who view,
in the immediate object of perception, a representative entity present to the
mind, but not a mere mental modification, and into those who hold that the
immediate object is only a representative modification of the mind itself"
(Metaph., lect. XVI.).
