"Matt Bailey was a synthetic personality. We invented him. We fed personality factors into a calculator, and we also fed into the calculator some highly informed guesses about just a few of the conditions likely to be encountered in space flight.
"We used the calculator to project the neural reactions of the synthetic person, Bailey, under the assumed conditions.
"Through kinevision, these sensations were reproduced in you.
"I need not labor the point. Space flight will be no Sunday outing. You deserve to know that—to know it with your feelings as well as your brains. And especially you young men should know it—you who are thinking about joining the volunteers. Frankly, we hope some of you will not volunteer. For though there is no Matt Bailey, there will be, someday, soon."
