the other is so pleased with his
musical compositions that he endeavors to show an analogy betwixt them
and souls. Now, we may understand harmony to arise from the intervals
of sounds, whose various compositions occasion many harmonies; but I do
not see how a disposition of members, and the figure of a body without
a soul, can occasion harmony. He had better, learned as he is, leave
these speculations to his master Aristotle, and follow his own trade as
a musician. Good advice is given him in that Greek proverb,

Apply your talents where you best are skill'd.

I will have nothing at all to do with that fortuitous concourse of
individual light and round bodies, notwithstanding Democritus insists
on their being warm and having breath, that is to say, life. But this
soul, which is compounded of either of the four principles from which
we assert that all things are derived, is of inflamed air, as seems
particularly to have been the opinion of Panaetius, and must necessarily
mount upward; for air and fire have no tendency downward, but always
ascend; so should they be dissipated that must be at some distance from
the earth; but should they remain, and preserve their original state,
it is clearer still that they must be carried heavenward, and this
gross and concrete air, which is nearest the earth, must be divided and
broken by them; for the soul is warmer, or rather hotter, than that
air, which I just now called gross and concrete: and this may be made
evident from this consideration--that our bodies, being compounded of
the earthy class of principles, grow warm by the heat of the soul.

XIX. We may add, that the soul can the more easily escape from this
air, which I have often named, and break through it, because nothing is
swifter than the soul; no swiftness is comparable to the swiftness of
the soul, which, should it remain uncorrupt and without alteration,
must necessarily be carried on with such velocity as to penetrate and
divide all this atmosphere, where clouds, and rain, and winds are
formed, which, in consequence of the exhalations from the earth, is
moist and dark: but, when the soul has once got above this region, and
falls in with, and recognizes, a nature like its own, it then rests
upon fires composed of a combination of thin air and a moderate solar
heat, and does not aim at any higher flight; for then, after it has
attained a lightness and heat resembling its own, it moves no more, but
remains steady,
