"The last point is essential and has its judicial function in all the circumstances of life. Without accuracy, common sense can not be satisfactorily developed, because it finds itself continually shocked by incoherency, resulting from a lack of exactness in the expression of opinions."
If we wish to know what the principal qualities are which form common sense, we shall turn over a few pages and we shall read:
"Common sense is the synthesis of many sentiments, all of which converge in forming it.
"The first of these sentiments is reason.
"Then follows moderation.
"To these one may add:
"The faculty of penetration;
"The quality consistency.
"Then, wisdom, which permits us to profit by the lessons of experience.
"A number of other qualities must be added to these, in order to complete the formation of common sense; but, altho important, they are only the satellites of those we have just named.
