So much about the facts. I could and should have formulated those yesterday. What kept me from doing so were the vistas opened by those facts. These are so enormous, so utterly incalculable that my mind went dizzy over these vast horizons. Consequently I mentally rejected the facts as impossible. Somebody once slapped Edison's face because he felt outraged by Edison's presenting a "talking machine." That's human nature, I suppose. Small wonder then that my ratio felt outraged as it was confronted with a machine that has a life and has a personality. Come to think of it: Human imagination has always conceived of such machines as a possibility, even a reality--in less rational times than our's that is.... Think of Heron's steam engine; it even looked like a man and was thought of as a magically living thing. Think of the Moloch gods which were furnaces. Think of all those magic swords and shields and helmets which were living things to their carriers. Think of the sailing ships; machines they, too; but what a life, what a personality they had for the crews aboard. Even in the last war pilots had their gremlins, their machines to them were living things. All imagination, of course, but then: everything we call a reality in this man-made world has its origin in man's imagination, hasn't it? Now, and to be exact as possible, what happened last night was this: 12:00. Entered station P. G. (pineal gland). Pulsemeter still at old place, not taken out for repair work as I had feared. Main Power current cut 12:20 as every night. Gus called to front room: rush of business as usual at that hour. 12:30. Reestablished closest approximation to preexisting conditions according to the most important of all experimental laws: "if some new phenomenon occurs, change _nothing_ in the arrangement of apparatus until you know what causes it." Plugged in from "nervusvagus" to "nervus trigeminus." Result: wave oscillations, pulse beatings as of yesterday. 12:45. Plugged in P. G.... 12:50. First manifestation of weird rasping sounds which precede speech formation. This followed by The Brain's calling signal; much clearer this time and slightly varied: "Lee, Semper Fidelis, 39; _sensitive_." (Note: the synthetic quality, the metallic coldness of that voice so incongruous with its emotional tones; it stands my hair on end.) 1 a.m.: (Approximately; things happen too fast). A veritable burst of whispering, breathless communications. As a person would speak over the phone when there are robbers in the house. The words fairly tumble over one another. The Brain uses colloquial American but after the manner of a foreigner who knows the phraseology only from books and feels unnatural and awkward about using it. I understand only about one half:
