The unique book "Left Psychopaths" by a modern right-wing conservative intellectual from New Zealand. Kerry Bolton, being an academic scientist, at the very beginning of his work with a frankly provocative and shocking name defines the boundaries of using a method based on the principles of the new science of "psychohistory." This science proceeds from the position that mass mental phenomena in world history did not arise on their own, in absolute isolation from circumstances, but are determined by the quality of the human material of the people in whose environment they spread. The mental conditions of the human masses and their biological hereditary basis are the dominant, primordial factor of all revolutionary movements.
