My personal conviction is that science is concerned wholly with truth, not with ethics.
In a tribal organization, even in time of peace, service to tribe or state predominates over all self seeking in war, service for the tribe or state becomes supreme, and personal liberty is suspended.
Man is by nature competitive, combative, ambitious, jealous, envious, and vengeful.
Under no stretch of imagination can war be regarded as an ethical process yet war, force, terror, and propaganda were the evolutionary means employed to weld the German people into a tribal whole.
