...as man under pressure tends to give in to physical and intellectual weakness, only great strength of will can lead to the objective. - Carl von Clausewitz

As we admire presence of mind in a pithy answer to anything said unexpectedly, so we admire it in a ready expedient on sudden danger. Neither the answer nor the expedient need be in themselves extraordinary, if they only hit the point; for that which as the result of mature reflection would be nothing unusual, therefore insignificant in its impression on us, may as an instantaneous act of the mind produce a pleasing impression. The expression “presence of mind” certainly denotes very fitly the readiness and rapidity of the help rendered by the mind.

Whether this noble quality of a man is to be ascribed more to the peculiarity of his mind or to the equanimity of his feelings, depends on the nature of the case, although neither of the two can be entirely wanting. A telling repartee bespeaks rather a ready wit, a ready expedient on sudden danger implies more particularly a well-balanced mind.
