"Not this particular insect, perhaps. In the building it seemed to move slowly, with a shuffling sound. I was afraid it could move swiftly and that made me hesitate to make a dash for the entrance. But now we can't afford to let such a possibility demoralize us. We've got to seize on the doubt and build it up in our minds. Build it up, do you understand? Make ourselves believe it."

"But the creature is winged! David, I thought—"

"Don't think. Just make yourself believe. Not all winged insects can fly. The wings may be vestigial. You've got to believe that it's slow moving and blot its size from your mind. We instinctively think of insects as small, visualize them as small. Hold fast to that visualization. You can if you try."

"You mean deliberately distort the truth, cling to an illusion which we know, deep in our minds, can't possibly be true?"

"Only in regard to its size. It may well be slow-moving. That margin of doubt gives us an advantage we'd be foolish to abandon. If we can control our fear in the right way we won't succumb to panic."

"The right way? Just what is the right way, David? How do you want me to feel?"

"As if you were being pursued by an insect on Earth. A dangerous insect, but small. We've got to stay alert to the danger without succumbing to a paralyzing fear. Just remember that it's not a baying, savage dog."

"All right, David. I'll try."

"Just will yourself to believe that we can save ourselves if we move fast enough. There's a very good chance that we can. We're in no more danger than we'd be if we were well ahead of a swarm of foraging army ants in the African jungle. We could outrun the ants easily enough by keeping our heads and keeping to the trail."

"You think they're trying to break down our resistance by making a deliberate attack on our minds. Is that it?"
