No figment was, however, even to the Velantians, actual or tangible. It was a picture upon a plate, transmitted from a well-defined point in space. There, upon that planet, was the actuality, eagerly awaited; toward and to that planet must the _Velan_ go at maximum blast. Into that line and at that blast, then, the pilots set their vessel without orders, and each of the crew saw upon his nonexistent plate that she had so been set. If she had not been, if the pilots had been able to offer any resistance, the crew would have slaughtered them out of hand. As it was, all was well. And Worsel, watching the affected portion of his mind accept these hallucinations as truths and admiring unreservedly the consummate artistry with which the work was being done, was well content. He knew that only a hard, solidly-driven, individually probing beam could force him to reveal the fact that a portion of his mind and all of his bodily control were being withheld; he knew that unless he made a slip no such investigation was to be expected. He would not slip. No human or near-human mind can really understand how the mind of a Velantian works. A Tellurian can, by dint of training, learn to do two or more unrelated things simultaneously. But neither is done very well and both must be more or less routine in nature. To perform any original or difficult operation successfully he must concentrate upon it, and he can concentrate upon only one thing at a time. A Velantian, however, can and does concentrate upon half-a-dozen totally unrelated things at once; and, with his multiplicity of arms, hands, and eyes, he can perform simultaneously an astonishing number of completely independent operations. The Velantian is, however, in no sense such a multiple personality as would exist if six or eight human heads were mounted upon one body. There is no joint tenancy about it. There is only one ego permeating all those pseudoindependent compartments; no contradictory orders are, or ordinarily can be, sent along the bundled nerves of the spinal cord. While individual in thought and in the control of certain actions, the mind-compartments are basically, fundamentally, one mind. Worsel had progressed beyond his fellows. He was different; unique. In fact, the perception of the need of the ability to isolate certain compartments of his mind, to separate them completely from his real ego, was one of the things which had enabled him to become the only Second-Stage Lensman of his race.
