"In a profound sense every man has two halves to his being: he is not one person so much as two persons trying to act in unison. I believe that in the heart of each human being there is something which I can only describe as a "child of darkness" who is equal and complementary to the more obvious "child of light." Whether we know it or not we all have within us a natural instinctive man, a dark brother, to whom we are irrevocably joined as to our own shadow. However much our conscious reason may reject him, he is there for good or ill, clamouring for recognition and awareness and a fair share of life just as the less conscious black man of Africa is struggling and clamouring for life, light and honour in our societies. I need not emphasize how the rational, calculating, acutely reasoning and determined human being that Western man has made of himself has increasingly considered this side of himself not as a brother but as an enemy, capable, with his upsurges of rich emotion and colourful impulses, of wrecking conscious man's carefully planned and closely reasoned way of existence."
