"The modern architectural environment may cater to the eye, but it often lacks the pungent personality that varied and pleasant odors can give. Odors lend character to objects and places making them distinctive, easier to identify and remember. Odors are important to human beings. We have even spoken of an olfactory world, but can fragrances and scents constitute a world? "World" suggests spacial structure. An olfactory world would be one in which they appear in random succesion or as incoate mixtures. Is it possible to argue that taste, odor and even hearing cannot in themselves give us a sense of space?"
