" We are very apt to think of the ego as powerless against the id; but when it is opposed to an instinctual process in the id it has only to give a ‘signal of unpleasure’ in order to attain its object with the aid of that almost omnipotent institution, the pleasure principle. To take this situation by itself for a moment, we can illustrate it by an example from another field. Let us imagine a country in which a certain small faction objects to a proposed measure the passage of which would have the support of the masses. This minority obtains command of the press and by its help manipulates the supreme arbiter, ‘public opinion’, and so succeeds in preventing the measure from being passed. "
