"Which of you wishing to construct a tower does not first sit down and calculate the cost to see if there is enough for its completion? Otherwise, after laying the foundation and finding himself unable to finish the work the onlookers should laugh at him and say, 'This one began to build but did not have the resources to finish.' Or what king marching into battle would not first sit down and decide whether with ten thousand troops he can successfully oppose another king advancing upon him with twenty thousand troops? But if not, while he is still far away, he will send a delegation to ask for peace terms."
