"--Thus man Has incessantly
fluctuated between his two natures; some-
times his thoughts have disentangled him
from his sensations;           his sensa-
tions have absorbed his thoughts, and he has
wished, successively, to refer every thing
to one or the other: it however appears to
me, that the moment for a fixed doctrine
has arrived* Metaphysics are about to un-
dergo a revolution, like that which Coperni-
cus has produced in the system of the world.
