You do not understand Christian Science" is the usual reply of the followers of Mrs. Eddy to any one disputing their claims, or trying to point out the many inconsistencies in their creed. If it is impossible to understand Christian Science, how does it expect to propagate itself? To answer that one must accept the doctrine before one can understand it would be like asking a man to see before he opens his eyes, or to think after he has made up his mind. It is just as useless to try to understand Christian Science after it has been accepted as true as it would be for a judge to examine the evidence after a verdict has been pronounced. And if Christian Scientists can understand the beliefs which they reject, why may not other people have intelligence and honesty enough to understand Christian Science without believing in it?

But can a person who is not a mathematician understand or discuss profitably the intricate problems of mathematics? No; hence no one but a Christian Scientist may discuss its doctrines and interpret its metaphysics. Neither has that defence any value. We do not have to be expert mathematicians to know that twice two make four. It is possible to detect an error in an example of addition, multiplication, or subtraction presented by the greatest mathematician without possessing equal knowledge or ability. Mrs. Eddy may be more advanced in metaphysics than any of her critics, but twice two make four in "Divine science" as well as in human science. Square your statements with the facts, and you disarm criticism. Ignore, suppress, or tamper with the facts, and you will have the universe against you.
