What exactly is common sense? Mark Twain hit a bull’s-eye with his definition: “Common sense is the simple knack of seeing something the way it really is and doing something the way it should be done.” That just about covers it.
According to Einstein, common sense is a collection of prejudices acquired by age 18. If, what he means by prejudice is a way of thinking and looking at life, then this is a pretty accurate observation. When we say common sense we mean common to most people.
However, common sense is not so common. It is particular to the values and groups in which we were raised. The values of different groups are evident in the common sense of each group.
Common sense is the one virtue that is used by us at every step. Even animals have it, which it seems to instinctively show at unexpected moments.
We often look upon common sense as a blind instinct. It is a quality that neither wealth nor learning can confer on a man. It is supposed to come as a gift, and that one is born with,—a sharp insight into matters and promptitude that helps us much in the practical field of work.
Common sense is only the combination of experience with intelligence. The learned man may be a wonderful theorist, a man of many devices. But when faced with a situation, he may get utterly lost.
The uncommon never escapes the shrewd judgment of common sense.
