_It was a curious word for him to have used--nuance--because six months later in Dr. Freylinghuysen's office Blackburn and Shaheen were to tangle over the nuance of blue versus green, a matter of observation which compared in subtlety to apples versus bananas, Shaheen saying heatedly: "The dress was blue. I'm not color blind and I have twenty-twenty vision. I'll stake my reputation as an experimental physicist on it."_ Blue! _And this was a lucid well defined statement of his position, a statement rivaled in lucidity only by that of Blackburn who had in all sincerity to insist that the dress_ was _blue--but only 10:31 that morning at which time it turned_ green; _and if that wasn't bad enough a panting red faced chaplain Rowan had to dash in, carefully locking the door behind him and taking out a huge swatch of dress which he plunked down on the desk shouting: "Green, green, green! Green as the envious devils of hell! Green I say! Green before, green after, green for eternity!"_ "I think, in spite of all," Blackburn remarked, "you've managed to find a way." "No, but that's interesting," Shaheen said. "Semantically, anyway. _I will did._ Curious." "A grammatical revolution!" Pendelton was telling them that first day. "I do, I did do, I will do. I have done, I will have done. I do, I did do, I will do. I have done, I will have done, I should have done, I will did! They're all the same now! So you see, I'm not really wasting your time. The future and the past are now united in a fantastic tenseless embrace. At some time in the future I can in the past save Caesar's life. Thus, there being no more future and past, how can I be wasting your time?" "More than curious," Pendelton replied. "Practical. The Greeks as you may know thought that no man could be sure he had a happy life until it was over. I on the other hand assert that Caesar's assassination is still in doubt because of the future-past equivalence, that he has not yet successfully crossed the Rubicon, that he is still swimming to the Alexandrian lighthouse, that he is not yet emperor of a Rome that has not yet fallen! Not emperor and yet ... emperor. Not yet fallen and yet ... fallen and gone like--what? The wind? No, not even the wind. Nothing is gone, it's all still there moiling and seething around in temporal abeyance. Waiting to be resolved! Give me a time machine and I can mold every second of Caesar's existence and, incidentally, by extension, my own. The Greeks therefore were wrong. A man can no longer be sure he was happy even when he's dead!" * * * * * Blackburn leaned back in his chair and inquired blandly: "Did we get to the great implication yet?"
