"Reason," declares Mrs. Eddy (Science and Health, p. 327), "is the most active human faculty." In fact, human reason accompanies and generally controls every department of life. Because of the importance of reason in decision making, care should be exercised to determine what controls it. Is it love, or is it hate and fear? Is it wisdom, or is it self-will and suspicion? Is it spiritual understanding, or is it misunderstanding and ignorance?
To allow the spiritual qualities of God to guide reason is scientific, for this attitude correctly acknowledges the supreme power of God as present and available for use in our earthly affairs. To allow mortal motives and considerations to guide our thoughts is atheistic, for in belief it would put matter and evil in a position of supremacy above God.
In Proverbs (4:5) we are advised, "Get wisdom, get understanding: forget it not." And how do we get these qualities or make them active in our lives? By turning to God and acknowledging Him as the only Mind or Principle, the only source of understanding. Here again reason is important, for it leads the receptive consciousness on to complete trust in God. Reason leads one to the obvious conclusion that he exists and that there must be a power or presence which supports his existence.
