Did you ever consider the proposition that error is—in a sense—proof of Truth?
How can this be?
Obviously a lie cannot be told about nothing; it can only counterfeit a truth. So whenever we detect a lie—and this is important—we can start looking for the opposite truth. The true fact must be there, or the lie could not even seem to exist. This is a basic point in Christian Science, which demonstrates that evil is always a lie, counterfeiting the fact of God's, Truth's, allness. Mrs. Eddy writes, "The use of a lie is that it unwittingly confirms Truth, when handled by Christian Science, which reverses false testimony and gains a knowledge of God from opposite facts, or phenomena."
