Believe me (the style and the writing was a little less urgent again now), I've had all the intellectual stuffing knocked out of me here. We all have had, for that matter. We're supposed to be the cream of the crop, but imagine sitting down to instruction from people whose I.Q.s start where yours leaves off! But what has really made most of us here feel pretty humble is the way they have demolished Earth's so-called "scientific method"—and used the method itself to prove that it doesn't stand up! You know how we've always been taught to observe, collect data, then erect a theory to fit the data, a theory which has to be modified when other data came along which don't fit into it. Here they work the opposite way—they say: "Know the fundamental principles governing the operation of the universe and then all the pieces fit together inside this final Truth." I understand now why so many of the Oak Ridge boys turned to religion after they had been exposed to the electron microscope for a while—they realized they had gone as far as their "scientific" training would ever take them. Time and space are running out. I know all this must sound confused and incredible, Dick; I'm still confused myself. But I want you to think about what I've written, then take the action you think best. I know it won't be easy for you. If you think this is some maniac's idea of a joke, you'll have proof very soon that it isn't, because one of the people at your Center is due to leave for here any time now. You're wondering why I used this weird and wonderful means of communication. The problem was to find a writing material which would stand up in Earth's atmosphere—oddly enough, it's not the oxygen which causes the trouble, but the so-called "inert" nitrogen. The container will probably not disintegrate for a couple of days at sea level atmospheric pressure, but this material I'm writing on would not last more than a few seconds. That's one reason they picked you—most people just don't have a spare decompression chamber up in the attic! The other reason was that with your photographic memory, you'll know this is my handwriting, beyond the shadow of a doubt, I hope. I'm sure you've sat in that pressure suit long enough. But remember, if you want to take another look at this, you'll have to put it back in the container before you go "down."
