murderers, whose love of murder was in their blood as it is perhaps also in ours. The ethical strivings of mankind, with the strength and significance of which we need not quarrel, are an acquisition of the history of man; they have since become, though unfortunately in very variable quantities, the hereditary possessions of people of today.
Let us now leave primitive man and turn to the unconscious in our psyche. Here we depend entirely upon psychoanalytic investigation, the only method which reaches such depths. The question is what is the attitude of our unconscious towards death. In answer we say that it is almost like that of primitive man. In this respect, as well as in many others, the man of prehistoric times lives on, unchanged, in our conscious.
