“No civilization can progress to the stability of continuous survival without certain and sure command of knowledge such as that contained in Dianetics. For Dianetics, skillfully used, can do exactly what it claims. It can, in the realm of the individual, prevent or alleviate insanity, neurosis, compulsions and obsessions and it can bring about physical well-being, removing the basic cause of some 70% of man's illnesses. It can, in the field of the family, bring about better accord and harmony. It can, in the field of nations or smaller groups such as those of industry, improve management to a point where these pitifully inadequate ideologies, for which men fight and die with such frightening earnestness, can be laid aside in favor of a workable technology.”
