An explanation first: Apparently this is the old name for the Simple-Minded Wisdom
trope, but the page is still there - and almost empty.
We shouldn't leave it like that. Now I had the idea to turn it into a Useful Note. What do you think about this?
This would make a good page quote:
"Common sense (which, in truth, very uncommon) is the best sense I know of: abide by it, it will counsel you best. Read and hear, for your amusement, ingenious systems, nice questions subtilly agitated, with all the refinements that warm imaginations suggest; but consider them only as exercitations for the mind, and turn always to settle with common sense." (Letters to His Son
, letter 52)
