@Mame,
It seems that you can't read, Mame. Even your own sources.
involving, allowing, or causing deep thought
It also seems that your comprehension skills are also somewhat lacking.
Air, desert or otherwise, cannot be contemplative,
Quote:And as I jogged toward my room, I was reminded that in the end we all return to where we started. I had small blisters on my toes, which I learned was because my skin had softened in the contemplative desert air. My whole being had become more sensitive and open.
It doesn't say that the "air" is contemplating. It says that the desert air/atmosphere easily allows one to fall into a contemplative mood.
I have actually found sitting in the desert highly conducive to a contemplative mood. The air, the atmosphere, the rugged beauty all help one fall into such a frame of mind.
Here are a few examples of what you say can't exist.
"He has his own thing going on with that horn, and it's underscored by a much more contemplative air;"
"Smooth moody jazz with a contemplative air,"
"Many of the songs have a slow, contemplative air, like "Contemplation", "Cedar Creek", and "Baby Steps".
Check your source once more. You'll find, "a contemplative book ". I think that you can figure out that that doesn't suggest a book sitting in an easy chair in front of the fireplace contemplating the meaning of life.
