furnished a key to modern thought. As a
co-operative science it has had a stimulating influence on all lines of
research, not only in scientific study of physical nature, but also in
the study of man, for there are natural laws as well as man-made laws
to be observed in the development of human society.

Some evolutionary scientists will be dogmatic at times, but they return
to their laboratories and proceed to reinterpret what they have
assumed, so that their dogmatism is of short duration. Theological
dogmatists are not so fortunate, because of persistence of religious
tradition which has not yet been put fully to the laboratory test.
Some of them are continuously and hopelessly dogmatic. They still
adhere to belief founded on the emotions which they refuse to put to
scientific test. Science makes no attempt to undermine religion, but
is unconsciously laying a broader foundation on which religion may
stand. Theologians who are beginning to realize this are forced to
re-examine the Bible and reinterpret it according to the knowledge and
enlightenment of the time. Thus science becomes a force to advance
Christianity, not to destroy it.

On the other hand, science becomes less dogmatic as it applies its own
methods to religion and humanity and recognizes that there is a great
world of spiritual truth which cannot be determined by experiments in
the physical laboratory. It can be estimated only in the laboratory of
human action. Faith, love, virtue, and spiritual vision cannot be
explained by physical and chemical reactions. If in the past science
has rightly pursued its course of investigation regardless of spiritual
truth, the future is full of promise that religion and human reactions
and science will eventually work together in the pursuit of {469} truth
in God's great workshop. The unity of truth will be thus realized.
The area of knowledge will be enlarged while the horizon of the unknown
will be extended. The mystery of life still remains unsolved.

Galton followed along in the study of the development of race and
culture, and brought in a new study of human life. Pasteur and Lister
worked out their great factors of preventive medicine and health.
Madame Curie developed the radioactivity as a great contribution to the
evolution of science. All of this represents the slow evolution of
science, each new discovery quickening the thought of the age in which
it occurred, changing the attitude of the mind
