Man and His Symbols

Disagreement functions as a vehicle of mental life in society, but it is not a goal; agreement  is equally important.

Because psychology basically depends upon balanced opposites, no judgment can be considered to be final in which its reversibility has not been taken into account.

The reason for this peculiarity lies in the fact that there is no standpoint above or outside psychology that would enable us to form an ultimate judgment of what the psyche is. ~Carl Jung, Man and His Symbols, Page 59
