T 2.3.10.5

To remove this contradiction, we must consider, that there are certain desires and inclinations, which go no farther than the imagination, and are rather the faint shadows and images of passions, than any real affections. Thus, suppose a man, who takes a survey of the fortifications of any city; considers their strength and advantages, natural or acquir'd; observes the disposition and contrivance of the bastions, ramparts, mines, and other military works; 'tis plain, that in proportion as all these are fitted to attain their ends, he will receive a suitable pleasure and satisfaction. This pleasure, as it arises from the utility, not the form of the objects, can be no other than a sympathy with the inhabitants, for whose security all this art is employ'd; tho' 'tis possible, that this person, as a stranger or an enemy, may in his heart have no kindness for them, or may even entertain a hatred against them.
