You sometimes get a thrill at knowing where you are. You’re often filled with wonder, but more often you are puzzled. You are reminded, again and yet… - Clifford D. Simak

A machine, a mechanism, no more than a tool — technological brother to the hoe, the wrench, the hammer — and yet as far a cry from these as the human brain was from that first amino acid which had come into being on this planet when the Earth was very young. One was tempted, Enoch thought, to say that this was as far as a tool could go, that it was the ultimate in the ingenuity possessed by any brain. But that would be a dangerous way of thinking, for perhaps there was no limit, there might, quite likely, be no such condition as the ultimate; there might be no time when any creature or any group of creatures could stop at any certain point and say, this is as far as we can go, there is no use of trying to go farther. For each new development produced, as side effects, so many other possibilities, so many other roads to travel, that with each step one took down any given road there were more paths to follow. There'd never be an end, he thought — no end to anything.

Bit by bit, as the legend unfolds, the reader gets a more accurate picture of the human race. By degrees, one gains the conviction that here is a race which can be little more than pure fantasy. It is not the kind of race which could rise from humble beginnings to the eminence of culture with which it is gifted in these tales. Its equipment is too poor.
So far it lack of stability has become apparent. Its preoccupation with a mechanical civilization rather than with a culture based on some of the sounder, more worthwhile concepts of life indicates a lack of basic character.
And now, in this tale, we learn of the limited communications which it possessed, a situation which certainly is not conducive to advancement. Man’s inability to understand and appreciate the thought and the viewpoint of another man would be a stumbling block which no amount of mechanical ability could overcome.

I’m just a propagandist and a propagandist doesn’t have to know what he is talking about, just so he talks about it most convincingly.
