“Experience has taught the author that evil is similar to disease in nature, although possibly more complex and elusive to our understanding. Its genesis reveals many factors, pathological, especially psychopathological, in character, whose essence medicine and psychology have already studied… [A] comprehension of the essence and genesis of evil generally makes use of data from [biology, medicine, and psychology]. Philosophical reflection alone is insufficient.” (Lobaczewski, 98)
Like a color blind man incapable of distinguishing red from green, a small minority of the human population cannot experience or fully comprehend the normal range of human emotions. And like those color blind who may conceal their condition by using the correct words while not understanding their meaning (e.g., the top traffic light is “red”, the bottom is “green”) - so does this minority conceal their condition by playacting an emotion's exterior signs (facial expressions, exclamations, body language). However, they do not actually experience the emotion in question. Their deception is revealed in the laboratory, where they respond to words like DEATH, CANCER, DISEASE, as if they were DAY, CREAM, or PAPER. They lack the ability to comprehend the emotional “punch” that certain words contain. They use others’ emotional reactions as cues, and they adjust their behavior to portray the correct ‘emotional’ behavior. (Hare, 129-30)
