I found myself today wondering on the phrase “The sky’s the limit.”
If, when considering ‘the sky’, we are imagining that 62-75 miles or so (100-120 km, for us nerds) of the earth’s atmosphere – as I think most people do -, it has me wonder two things in quick succession.
First: How old is that phrase?
Then: In what kind of sad and limited mental world must one live to have the sky alone, out of the whole universe (and whatever might be beyond), be the limit of one’s dreams and such?
How could someone have gotten to the Moon with such a limitation on one’s thinking?
It sounds – initially, anyway – like a declaration of near-limitless possibilities… today, however, upon a bit of consideration, I must say that it feels rather restrictive and of a field of rather small thinking.
Is this just a matter of timing, that the moon and Mars explorations hadn’t happened yet, and were still too far into the future for anyone to notice?
