The Description of a New World, Called the Blazing-World

Yes, answered the Spirits; for every human Creature can create an Immaterial World fully inhabited by Immaterial Creatures, and populous of Immaterial subjects, such as we are, and all this within the compass of the head or scull; nay, not onely so, but he may create a World of what fashion and Government he will, and give the Creatures thereof such motions, figures, forms, colours, perceptions, &c. as he pleases, and make Whirl-pools, Lights, Pressures, and Reactions, &c. as he thinks best; nay, he may make a World full of Veins, Muscles, and Nerves, and all these to move by one jolt or stroke: also he may alter that World as often as he pleases, or change it from a Natural World, to an Artificial; he may make a World of Ideas, a World of Atoms, a World of Lights, or whatsoever his Fancy leads him to. And since it is in your power to create such a World, What need you to venture life, reputation and tranquility, to conquer a gross material World? For you can enjoy no more of a material world then a particular Creature is able to enjoy, which is but a small part, considering the compass of such a world; and you may plainly observe it by your friend the Empress here, which although she possesses a whole World, yet enjoys she but a part thereof; neither is she so much acquainted with it, that she know all the places, Countries, and Dominions she Governs.
