Primary – Humans are wildly complex psychological beings that change depending on situation and health.
Secondary – Because of vast psychological differences it is hard for humans to often understand one another’s perspective.
Tertiary – There is no such thing as a stable person, only stable situations. Because of this personalities are malleable and change to account for different qualities that are in demand in varying situations.
Supporting – Though personalities are dissected and studied across multiple different personality typing systems the core elements of personality can still be predicted by basic human nature.
Concluding – Because of our quickly changing personalities and tendencies we must be able to rely on the stagnant qualities of human interaction that keep communities at peace.
