This is not the place to discuss how this change in outlook was fostered by the uncritical transfer to the problems of society of habits of thought engendered by the preoccupation with technological problems, the habits of thought of the natural scientist and the engineer, and how these at the same time tended to discredit the results of the past study of society which did not conform to their prejudices and to impose ideals of organization on a sphere to which they are not appropriate.

Is there a greater tragedy imaginable than that, in our endeavor consciously to shape our future in accordance with high ideals, we should in fact unwittingly produce the very opposite of what we have been striving for?

It is not difficult to deprive the great majority of independent thought. But the minority who will retain an inclination to criticize must also be silenced....Public criticism or even expressions of doubt must be suppressed because they tend to weaken pubic support....When the doubt or fear expressed concerns not the success of a particular enterprise but of the whole social plan, it must be treated even more as sabotage.
