Intelligence gathering and the relationship between rulers and spies: some lessons from eminent and lesser-known classics

This paper aims to examine the relevance of intelligence gathering as an essential prerequisite for any political or military decision, and the resulting special relationship between rulers and spies, through a theoretical comparison between renowned classics and niche literature on strategy, literature, philosophy and political science belonging to several periods and historical contexts. Findings suggest that criticism on intelligence does not concern its utility, but rather the reliability of the sources, the obstacles presented by intelligence gathering and the ethics of spying. Spies are often described as ‘ramifications’ of the ruler, to whom they are tied by a special relationship of trust, rooted in a spirit of sacrifice, adequate remuneration and honours.
