Theory and application are two sides of a single talent. They cannot be separated. To have full value, they must be spent as a whole coin. Truth is never on the defensive. Nor is the search for truth.
Truth is the sword of justice.
Truth destroys error. Therefore, make no apology in your search for truth. Then, neither exists. If the blade of the sword is truth, then its handle must be confidence. Grip it in both hands courageously.
