never this graduation, but slopes his thought, however picturesque the
precipice on one side, to an access from the plain. He never writes
in ecstasy, or catches us up into poetic rapture.

Plato apprehended the cardinal facts. He could prostrate himself on
the earth, and cover his eyes, whilst he adorned that which cannot be
numbered, or gauged, or known, or named: that of which everything can

of heaven to earth, of matter to mind, of the part to the whole, is

sciences, even the best,--mathematics, and astronomy, are like
sportsmen, who seize whatever prey offers, even without being able to
make any use of them. Dialectic must teach the use of them. "This is
