I think it is a sign of habitual cynicism that you assume "One small step for man, one giant leap for mankind." was said by a politician. I think people feel like they are defending themselves from being manipulated by not accepting anything on its face as sincere. Sometimes a pipe is just a pipe.
That's correct about Freud! I was referring to Magritte, who made the painting "Ceci n'est pas une pipe." By which he meant the image of the pipe was not actually not a pipe. Which means .. well I think you would have to read about it and I am not sure I am using the reference in the right way.
I believe Freud and the cigar is about our thoughts and impulses sometimes not having greater meaning in our subconscious. Magritte is about something different.
