"Locke supposes that a person acquainted sensibly with the colours which compose a rainbow, can by the names of such colours in a verbal description, be made visually acquainted with a rainbow. The verbal description will give such a person's intellect a good verbal definition of the word rainbow, but it cannot communicate the sight to the extent that it differs, in any manner from the sights he already knows."

“Man soon finds what he wants to find. If he cannot find it otherwise, he creates it for his special enjoyment: for instance, if a man wants to see a ghost, he need only promulge his wish some night around a decaying fire, with a few alarmed and shocked listeners. Then let him ascend in the dark to a remote chamber, carefully looking over his shoulder every few moments; and if he will not see a ghost, he will feel as if he saw one, and that will be tantamount thereto.”

“Among its curiosities is a high rock, which overhangs a fearful precipice, whose bottom is just as much below the surface of the surrounding country as the summit of the rock is above the surface. From its summit the rock presents the most enchanting views that the country affords... The atmosphere exerts, however, a medical influence. While inhaling it, each person possesses in imagination whatever he desires at the moment: riches, health, power, or even a lady's love. The place is appropriately termed the pinnacle of hope. ...Hither come ...all persons who wish to cheat the present moment of its anguish by pleasant anticipations of the future. Occasionally, however, a peculiar madness seizes the visiters, and they jump from the delightful pinnacle into the abyss below, whose noxious vapours prostrate all the energies of life, and reverse all the reveries of hope.”

“In Boresko, the government, though imperial, grants the people some power. They collect annually, and, marching to the palace, signify to the emperor their wishes, which he is constrained to respect. To march at the head of such a procession confers power and influence, and those who thus march are called political leaders.”

“To jump occasionally into the pit is common to all who visit the mountain, and to some who keep on the plain; but the madness to which I have alluded consists in rapid alternations from the mountain to the pit, annoying all persons who are forced, by friendship or consanguinity, to consort with the unfortunate maniacs. To remain permanently either on the pinnacle or in the abyss is deemed a species of the same disorder, though not so common.”

“All that the book contains is the elucidation of but one precept: namely, to interpret language by nature. We reverse the rule and interpret nature by language.”
