“There are some essential truths which modify daily life without, for this reason, lessening their importance.

“Some of them are of premature development; others are of miniature growth.

“To reason without offending common sense, it is, therefore, indispensable to consider time, place, environment, and all the contingencies which could arise to undermine the importance of reasoning.”

After having reviewed all these phases, we shall then extend, in accord with Yoritomo, the last blade of this rudimentary fan, and we shall find judgment.

“This one is the index to that quality of mind called conviction.

“This mental operation consists in drawing together many ideas that their relative characteristics may be determined.

“This operation takes the place contiguous to reasoning, of which it is the result.

“Judgment determines its character after having registered the reasons which ought to indicate its position; it deducts the conclusions imposed by the explanatory principle, and classifies the idea by submitting it to the valuation placed upon it by judgment.

“All judgment is either affirmative or negative.

“It can never be vascillating nor neutral.

“In this last case it will assume the title of opinion, and will attribute to itself the definite qualities which characterize judgment.

“It is, however, at times subjected to certain conditions, where the principles on which it is based are not sufficiently defined, and, therefore, becomes susceptible to a change, either of form or of nature.

“It is possible, without violating the laws of common sense, to establish a judgment whose terms will be modified by the mutation of causes.

“But common sense demands that these different influences should be foreseen, and that these eventualities should be mentioned when pronouncing the judgment.”

We have reached the last blade of the symbolic fan, described by the philosopher, for many secondary qualities may be placed between the principle blades.

But faithful to his explanatory method, he wished to indicate to us the broad lines first, and also to state the indispensable faculties constituting common sense, by teaching us their progression and development.

He desired to demonstrate to us also how much all these qualities would be lessened in value if they were not united and bound together in the order in which they ought to manifest themselves.

“We have all possest,” said he, “some fans whose point of reunion was destroyed in part or altogether lost.

“What becomes of it, then?

“During a certain length of time, always rather short, the blades, after having remained bound together by the thread which holds them, separate, when it is severed because of the lack of harmony and of equilibrium at their base.

“Very soon, one blade among them detaches itself, and the mutilated fan takes its place in the cemetery where sleep those things deteriorated because of old age or disuse.
