Just as a person has a physical capacity for self-reliance, which can be replaced with crutches if need be, so does one have psychic abilities for self-reliance, too: a capacity for love, a capacity for reason, and a capacity for productive activity. But it is also possible for a person to replace those innate psychic powers with an orientation toward having, such that a capacity for love, reason, and productive activity depends upon the possession of those objects of having upon which the heart is set.
