Brothels and colonies are two extreme types of heterotopia, and if one considers, after all, that the boat is a floating piece of space, a place without a place, that exists by itself, that is self-enclosed and at the same time is given over to the infinity of the sea and that, from port to port, from bank to bank, from brothel to brothel, goes as far as the colonies in search of the most precious treasures they conceal in their gardens, you will understand why, from the sixteenth century until the present, the boat has been for our civilization, not only the greatest instrument of economic development (I have not been speaking of that today), but also the greatest reserve of imagination. The ship is the heterotopia par excellence. In civilizations without boats, dreams dry up, espionage replaces adventure, and the police the pirates.

–Michel Foucault
