"Fortunately, the aliens are much too far from their home to possess anything like the number of personnel and other resources that we have. Otherwise, they would have beaten us long ago. Completely wiped us out. And all because an ordinary, intelligent human being cannot learn any patterns by which the aliens operate, and by which he can fight them successfully." "I know that," the commander muttered. "I spent plenty of time out there before I got tapped for this new branch of service." He rubbed the moist palms of his hands together nervously. "Certainly you did," the captain acknowledged absently. Then he continued his explanation. "Fortunately, there was a small body of information on extra-rational mental faculties that had been developed over the past century, and as soon as we expanded it sufficiently, we were able to form this new branch of service you now belong to. But unfortunately, some idiot in the Information Service released a popularization of the data on the new branch. That was ill-advised. The veterans who had survived so far had their own way of accounting for their survival, and that did not include what that silly description alluded to as 'blind guessing' by commanders of 'exceptional psychic gifts.' "Like most popularizations, the description was grossly inaccurate, and was promptly withdrawn; but the damage had already been done. The damage was completed by another idiot who named the new branch the Psi Corps, merely because the basic capacity for extra-rational mental faculties is technically signified by the Greek letter 'psi.' The name was slightly mispronounced by the men, and that automatically produced that nasty little nickname, which has stuck, and which expresses very well the attitude of the men toward the new service. "As I say, fleet discipline is very bad, and the men simply would not accept orders from such officers. There are numerous cases on record where they killed them when there was no other way out. "Now, as far as discipline itself is concerned, the best procedure would be to pull an entire fleet out of the defense perimeter and retrain them, because the newly trained recruits can be made to accept Psi Corps officers as commanders. But our situation is far too desperate to permit anything like that. Therefore, we must use whatever devices we can think of to do the job.
