The creation of the mental domain of phantasm has a complete counterpart in the establishment of "reservations" and "nature-parks."... The "reservation" is to maintain the old condition of things which has been regretfully sacrificed to necessity everywhere else; there everything make grow and spread as it pleases, including what is it useless and even what is harmful. The mental realm of phantasm is also such a reservation reclaimed from the encroachment of the reality-principle.
