"Master, I have been thinking about extraterrestial communications, as promised [100."
"Good. What is it you find?"
"First of all, since logic in ideation is universal, not merely mondial, the form of such an E.T. communication must be the same as one that we ourselves would send into space, given a degree of fundamental thinking and commonsense. Second, it must be based on the simplest principle, i.e. binary. Then, since it it unlikely that intelligent life in space can develop to a technical level, required for such communication, without the sense of sight, it is practically certain that the communication would be visual [41. But, seeing the time intervals, thousands of years, a question/answer system, a conversation, is ruled out. Therefore, the message will be complete and in the form of a lecture."
"Amazing! But why vision and not sound?"
"Because it is only by vision that you can start teaching, from scratch on, of any clever super-system, needed for complex ideation. Only by vision, e.g. can we teach our ridiculous alphabet, followed by our equally ridiculous grammar."
"Very good. You come, as would be expected, to the same conclusions as I did, and also as, ... and E.T. would. Thus we can expect, or could send-off, a range of +, and -, signals, grouped in blocks, squares of say, 2048 x 2048, or some other power of 2. But, probably, the separations between lines, and between 'pages', we would do by pauses. That's Natural. You see then, binary as it looks, it is in fact trinary." [41], [100], [207]
