nature; all it dreads is ignorance, and what is worse, error.
Error with regard to facts may be committed in two ways--by admitting as
facts what are not facts, and by denying facts. Now, there are facts
certain and well ascertained, numerous and widely known, connected with
some other portions of the border-land of science that we have not yet
looked into, though I have mentioned their names. He who would assert
that spiritism, table-turning, spirit-rapping, and so on are mere idle
talk, sheer impostures, is not well read in the literature of the
present day. By denying all reality to these phenomena he strays as far
from the truth as if he allowed himself to believe mere fabrications.
They are not impositions, but they are worse; they are superstitions. By
superstitions I mean here the practice of producing results which cannot
possibly proceed from the powers of nature, and which could not without
absurdity be attributed to the interference of the Creator or His good
angels.

Some persons strenuously object to introducing any reference to God into
scientific works. Science consists in tracing known effects to their
true causes. If there were no God, He could not be a true cause and it
would be unscientific to introduce His agency. But if there is a God and
He acts in the world which He has made, we must take His actions into
account when we study His works. Some say, "I do not believe in a God."
That may be, but that does not prove that there is no God. Belief is a
man's wilful and fine acceptance of what is proposed to him on the
authority of some one else. Students have most of their knowledge on the
authority of their professors and other men of learning. If a medical
student would say, "I do not believe in microbes nor in contagion by
disease germs," that would not kill the germs nor protect him against
contagion. Nor would it show his superior wisdom, but rather his
extravagant conceit and ignorance. So with those who believe not in God.

There are others who believe not in the existence of devils or fallen
angels. That is not so bad; but yet they must remember that their
refusal to believe in devils does not prove that there are none. The
greatest enemies of science are those who blindly maintain false
statements and false principles of knowledge. Let us look for the truth
in every investigation. Even Huxley, in the midst of his attacks on
dogmatic religion, protests also against dogmatic infidelity. Science,
