"Nine-tenths of tactics are certain, and taught in books: but the irrational tenth is like the kingfisher flashing across the pool, and that is the test of generals"

This quote by T. E. Lawrence talks to the value of instinct and imagination in the art of war. He recommends that while most of the tactics of war can be gained from books, the real test of a general is their ability to believe outside package and make choices on the fly. The kingfisher is utilized as a metaphor for this innovative spark, as it is able to quickly and suddenly dart across the swimming pool. This quote emphasizes the importance of having a creative and instinctive method to war, as it is this that will eventually identify the success of a general. It is not enough to just count on the methods taught in books, but rather a basic need to have the ability to believe rapidly and make decisions that are not always obvious.
