15. Spies cannot be usefully employed without a certain intuitive sagacity.

非聖智不能用間

Sun Tzu

Sun Tzu emphasizes the importance of gathering and using information in order to gain an advantage in warfare. This quote suggests that using spies or gathering intelligence is only useful if it is done with a certain level of understanding and insight, which can be gained through intuition or instinct.

Sources cannot be usefully employed without a certain intuitive insight and judgement.

Using sources in business requires a combination of skills, including intuition and sharp judgement. This type of information gathering can be useful for gaining a competitive edge, but only if it is carried out with skill and discretion. Without the ability to make quick, accurate decisions, sources may not be able to provide the valuable information that a business needs.

In addition to requiring a certain level of intuition and judgement, using sources of information in business also requires a combination of other skills. This might include the ability to identify relevant sources, to gather and analyze data in an efficient and effective manner, and to communicate the results of this analysis clearly and concisely. In order to gain a competitive edge, it is important for businesses to be able to use sources of information in a way that allows them to stay ahead of the curve and make strategic decisions. However, this requires skill and discretion in order to avoid misinterpreting or mishandling the information. Without the ability to make quick, accurate decisions, sources may not be able to provide the valuable insights that a business needs in order to succeed.
