425 that the more general and universal any of our ideas are, the less influence they have upon the imagination. A general idea, tho' it be nothing but a particular one consider'd in a certain view, is commonly more obscure; and that because no particular idea, by which we represent a general one, is ever fix'd or determinate, but may easily be chang'd for other particular ones, which will serve equally in the representation.

There is a noted passage in the history of Greece, which may serve for our present purpose. Themistocles told the Athenians, that he had form'd a design, which wou'd be highly useful to the public, but which 'twas impossible for him to communicate to them without ruining the execution, since its success depended entirely on the secrecy with which it shou'd be conducted. The Athenians, instead of granting him full power to act as he thought fitting, order'd him to communicate his design to Aristides, in whose prudence they had an entire confidence, and whose opinion they were resolv'd blindly to submit to. The design of Themistocles was secretly to set fire to the fleet of all the Grecian commonwealths, which was assembled in a neighbouring port, and which being once destroy'd, wou'd give the Athenians the empire of the sea without any rival. Aristides return'd to the assembly, and told them, that nothing cou'd be more advantageous than the design of Themistocles; but at the same time that nothing cou'd be more unjust: Upon which the people unanimously rejected the project.

A late celebrated historian admires this passage of antient history, as one of the most singular that is any where to be met with. 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. 'Tis a whole people interested in the proposal, which is made to them, who consider it as of importance to the public good, and who notwithstanding reject it''
