processes of investigation and comparison. But the largest part of
science is found in its method of approaching the truth as compared
with religion, philosophy, or disconnected knowledge obtained by casual
observation. In many ways it is in strong contrast with speculative
philosophy and with dogmatic theology, both of which lack sufficient
