Before diving into the
definition of uncommon sense,
let’s dive into the definition of common sense and nonsense.
When we talk about “common sense”, it means a practical knowledge or belief that is basic and not ridiculous to nearly all people at the
time.
In contrast, “nonsense” means a knowledge or belief that is ridiculous and is currently impossible to believe or achieve with the current situation, which include resources (
money, technology, etc.), or just simply impossible to do.
So “uncommon sense” is a term between “common sense” and “nonsense”. It means that at the
time when this belief is proposed, it is not a common belief among people, making it uncommon. However, the belief or idea is logical and possible, hence making it not impossible.
In
short, a possibility that is logical but not a common belief among people is “uncommon sense”
For example,
Before heliocentrism was proposed, Geocentrism had been a “
common sense” to the people at the
time being, but is also a “nonsense” to the people nowadays.
During Heliocentrism is being proposed, as geocentrism is the common belief at the
time, geocentrism had been a “common sense” to the people at the
time being, and a “nonsense” to the people now. But Heliocentrism is not nonsensical, as it is logical, then this possibility or hypothesis is an “uncommon sense” to the people at the
time being, and a “common sense” to the people now.
After Heliocentrism was proved to be correct, geocentrism turns to be a “nonsense”, which had been a “common sense” to the people in the past. And Heliocentrism turns from an “uncommon sense” into a “common sense” to the people now.
