Common sense is a simple and non-self-conscious use of logic.
That which today is called “common sense” is the remnant of an Aristotelian influence.
Americans are the most reality-oriented people on earth. Their outstanding
characteristic is the childhood form of reasoning: common sense. It is their
only protection. But common sense is not enough where theoretical knowledge is
required: it can make simple, concrete-bound connections—it cannot integrate
complex issues, or deal with wide abstractions, or forecast the future.
