Insidious concepts
Just so is it with the greatest sin. It is the most subtle,
and does its work almost self-deceived. The diseases
deemed dangerous sometimes come from the
most hidden, undefined, and insidious beliefs.
The pallid invalid, whom you declare to be wasting away
with consumption of the blood, should be told that blood
never gave life and can never take it away, - that Life is
Spirit, and that there is more life and immortality in one
good motive and act, than in all the blood which ever
flowed through mortal veins and simulated a corporeal
sense of life.
