Analogous conditions are sometimes seen in people suffering from a certain class of nervous ailments; the mind seems unimpaired, but co-ordination between the brain and certain muscles is almost wholly lacking.
To prevent such a condition, therefore, the staff must be kept in touch with the fleet; and it must also permit the fleet to keep in touch with the staff, by arranging that, accompanying the system of training, there shall be a system of education which will insure that the general plan will be understood throughout the fleet; and that the means undertaken to execute it will be made sufficiently clear to enable each person to receive the assistance of his own intelligence.

No man can do his best work in the dark.

Darkness is of itself depressing; while light, if not too intense, stimulates the activities of every living thing.
This does not mean that every mess attendant in the fleet should be put into possession of the war plans of the commander-in-chief, that he should be given any more information than he can assimilate and digest, or than he needs, to do his work the best.

Just how much information to impart, and just how much to withhold are quantitative questions, which can be decided wisely by only those persons who know what their quantitative values are.

This is an important matter, and should be dealt with as such by the staff itself.
