Truth is the survival instinct never quit running the show. For example, consuming only to the point necessary for survival, which satisfies other species, demonstrates the normal functioning of instinct.
Mankind engages in the behavior initiated by our survival instinct, then, leaving the point of survival far behind, charges on ever forward with no end in sight.
Individuals with more than they could ever use if they were to live multiple lifetimes, devote the only life they have to acquiring still more of what they can’t possibly use. This pattern exemplifies instinctual behavior in a state of disconnect.
