Wilhelm Stekel quotes
Many times I had spoken about "mental bipolarity" and proved that our affects are bipolar. Desire and disgust, love and hate, will-to-power and will-to-submission, are composed of negative and positive parts like the current of electricity. My contention was that any human affect has its own counterpart. Later Bleuler described this fact as "ambivalence," a term that was accepted by everybody, whereas previously they had laughed at my discovery, and given me the nickname "Stekel with his Bipolarity".
