The Theory of Balanceology frequently refers to the sub-branches of Needology and Wantology.
Needology = is the study of human inborn needs. At birth we inherent key core needs.
Wantology = is the study of learned wants. As we go through life we acquire the wanting of certain things.
Baruch Spinoza made a distinction between natural appetites (needs) and acquired appetites (wants).
Wants vs. Needs <—> needing vs. wanting
