Historian: The early Egyptian pharaohs spent as much wealth on largely ceremonial and hugely impressive architecture as they did on roads and irrigation systems. This was not mere frivolousness, however, for if people under a pharaoh' s rule could be made to realize the extent of their ruler' s mastery of the physical world, their loyalty could be maintained without military coercion.

["It is a conclusion purportedly justified by the argument's appeal to the psychological effects of these structures on the Egyptian population.", "It is a premise given in support of the claim that the loyalty of people under a pharaoh's rule was maintained over time without reliance on military force.", 'It is offered as an illustration of the principle that social and political stability do not depend ultimately on force.', 'It is offered in support of the claim that Egyptian pharaohs spent as much on ceremonial architecture as they did on roads and irrigation systems.']
