the action of gravity, not the cause
of it, so the theory of descent is
for explaining the origin of kinds of
life, not the origin OF life
Exact science has shown no con-
tinuOus passage from the inorganic to
the organic. Until a real connec-
tion is established between the two
worlds, the theory of evolution re-
mains incomplete; nevertheless, the
most comprehensive scientific struc-
ture of the nineteenth century will
ever be associated with Darwin
Darwin made definite what, on
philosophic grounds, Kant had
vaguely suggested and what Spen-
Ger all but arrived at before Dar-
wins announcement.
/ In Advance of Known Facts
In science there have been many
cases of theory being in advance Of
known facts. A recent instance is
the mechanical pressure of light In
1873 Clerk Maxwell proved that it
should exist, and deduced the value
of the pressure. His conclusion was
mathematically confirmed, in 1875,
by another scientist, on totally diff
| ferent grounds. In 1901, the me-
chanical pressure of light was actual
ly shown and measured. Later the
] experimental work was repeated
with more exactness, and there is no
doubt that the pressure has Max
wells value.
At the earth the pressure of the
! suns light is not quite a milligram
| per square metre of the earth's sur
face or 10000 tons on the whole
earth. If particle of earth is one
hundred thousandeth of an inch in
diameter, it is not attracted by the
sun, as the light pressure balances
the attraction of gravity.
Mechanical pressure of light ex-
plains what has long puzzled the
astronomers. They could not ac-
count for the fact that when a /
comet was moving away from the
sun the tail sometimes streamed
away in advance of the nucleus or
main body. AS 2,12re are in the tail |
particle -...vn less than the weight |
the sunlight can balance, they are
repelled instead of being atlr4c.cd. |
This force furnishes an explanation I
for those mysterious and beautiful
phenomena, the Corona, the Solar
Prominences, the Zodiacal Light and |
the Aurora Borealis
1t is belief in uniformity of ma
ture's laws that makes science pos
sible; to formulate those laws from
experiment, by reason and theory, !
is the work of science. Theories
stand or fall according to their suff-
cheney to account for the facts in |
nature, and may or may not rise to
the dignity of law.
intellect and Emotions
Let not the mistake be made of |
supposing that in mans life reason
every sphere. In occupation with |
the world of the material, let not |
the realm Of the spirit be ignored. |
Even that personifcation of intellect, |
Herbert Spencer, held that the emo
tions are masters and the intellect |
the servant
Rightly or wrongly, it is the heart |
that controls the beliefs as we'll as
the actions of the great majority of |
| mankind-hence the duty of educat- |
| ing the heart as well as the head, !
the spirit as well as the intellect. |
| It has been we'll advised that, to |
keep his mind sweet, the modern |
scientific man should be saturated |
with the Bible and Plato, with Ho-
mer, Shakespeare and Milton, and |
SO be enabled to strike a balance
between the rational and the emo |
| tional.
The ideal in mans life is as theory !
| in science. AS false theories may |
! prevail for time in one, so may /
low ideals govern in the other; as
true theory may he in advance of ex-
pertinent and even beyond its reach,
so may the pure ideal be ever be- |
yond the practice of men.
| AS theories in science will ulti.

with reality, so will ideals inevitably |
