Pla*ton"ic, n. A follower of Plato; a Platonist.

Pla"to*nism (?), n. [Cf. F. Platonisme.] 1. The doctrines or philosophy

by Plato or of his followers.

Plato believed God to be an infinitely wise, just, and powerful Spirit;

and also that he formed the visible universe out of preÎxistent

amorphous matter, according to perfect patterns of ideas eternally

existent in his own mind. Philosophy he considered as being a knowledge

of the true nature of things, as discoverable in those eternal ideas

after which all things were fashioned. In other words, it is the

knowledge of what is eternal, exists necessarily, and is unchangeable;

not of the temporary, the dependent, and changeable; and of course it

is not obtained through the senses; neither is it the product of the

understanding, which concerns itself only with the variable and

transitory; nor is it the result of experience and observation; but it

is the product of our reason, which, as partaking of the divine nature,

has innate ideas resembling the eternal ideas of God. By contemplating

these innate ideas, reasoning about them, and comparing them with their

copies in the visible universe, reason can attain that true knowledge

of things which is called philosophy. Plato's professed followers, the

Academics, and the New Platonists, differed considerably from him, yet

are called Platonists. Murdock.
