“ Even in the best of patients one can find glimpses into the depths of the psychopathic soul which is nothing but the immense egotism of the beast, worsted in the struggle for existence, tortured by the agonizing pangs of the fear instinct.In the vanity, conceit, arrogance, and overbearing attitude towards others, friend or stranger, as well as in the total indifference to the suffering of his intimate friends and acquaintances, we once more find the expression of that terrible selfishness which obsesses the psychopathic patient. ”
