56. As to its power on the body, I will endeavor to tell you, having
been myself much led into studies involving necessary reference both to
natural science and mental phenomena, what, at least, remains to us after
science has done its worst; what the myth of Athena, as a formative and
decisive power, a spirit of creation and volition, must eternally mean
for all of us.
57. It is now (I believe I may use the strong word) "ascertained" that
heat and motion are fixed in quantity, and measurable in the portions
that we deal with. We can measure portions of power, as we can measure
portions of space; while yet, as far as we know, space may be infinite,
and force infinite. There may be heat as much greater than the sun's, as
the sun's heat is greater than a candle's: and force as much greater than
the force by which the world swings, as that is greater than the force by
which a cobweb trembles. Now, on hear and force, life is inseparably
dependent; and I believe, also, on a form of substance, which the
philosophers call "protoplasm." I wish they would use English instead of
Greek words.
