David Hume

“ And tho' in the present case the advantage was immediate to the Athenians, yet as it was known only under the general notion of advantage, without being conceiv'd by any particular idea, it must have had a less considerable influence on their imaginations, and have been a less violent temptation, than if they had been acquainted with all its circumstances: Otherwise 'tis difficult to conceive, that a whole people, unjust and violent as men commonly are, shou'd so unanimously have adher'd to justice, and rejected any considerable advantage. ”

“ Of the influence of the imagination on the passions.
'Tis remarkable, that the imagination and affections have a close union together, and that nothing, which affects the former, can be entirely indifferent to the latter. Wherever our ideas of good or evil acquire a new vivacity, the passions become more violent; and keep pace with the imagination in all its variations. ”

“ The same reasons, which render it so easy for philosophers to establish these sublime maxims, tend, in part, to diminish the merit of such a conduct in that people. Philosophers never ballance betwixt profit and honesty, because their decisions are general, and neither their passions nor imaginations are interested in the objects. ”

“ Here, says he, they are not philosophers, to whom 'tis easy in their schools to establish the finest maxims and most sublime rules of morality, who decide that interest ought never to prevail above justice. ”
