| | Common..what is common?
Once you define Common sense, you begin to define what it is not. Who is to say one definition is more common (or better) than the other?
Does it require 10 people to make sense, common? How bout 100? Does it matter who the sample is made up of? Does it account for culture? How about generational differences?
If a 22 year old and an 88 year old are asked to define common sense, they may very well have 2 different answers -- who is right? Is wisdom right or are current trends right?
When someone says "Use some common sense" -- are they not really saying "think more like me (or people like me)"? What is the difference?
The challenge with common sense is that it is not really all that common. If it were, would we really have to define it?
