Christian Science can deny the existence of ill health only at the cost of logically denying the existence of good health also. Both are differing conditions of the same thing--the body. Christian Science calls sickness a lie. Then it should likewise call its opposite a lie. But not only does it not: it actually affirms that good health is a truth and a reality even while it denounces matter--the body--as a lie and an illusion! If, in spite of its deformed logic, Christian Science still gets healing done--as it does--this result must be attributed to the fact that the infinite Life-Power does take cognizance of the body's disease and does not deny its being there.
