"I am supposing that one person says to another, I have just met a negro.
The interlocutor, as well as he who mechanically registers this fact,
without thinking, gives himself up to analysis and to coordination which
always precedes synthesis.

"Without being aware of this mental action, their minds will be occupied
first with the operations of perception then of classification.

"This negro was a man of a color which places him in a certain group of
the human race.

"It is always thus that common sense proceeds, its principal merit being
to know how to unite present perceptions with those previously cognized,
then to understand how to coordinate them so as to be able to group them
concretely, that is to say, to synthesize them.

"Destination is defined as the purpose or object, born of deduction and
of classification.

"Destination does not permit of losing sight of the end which is
proposed.

"It allows the consideration of the purpose to predominate always, and
directs all actions toward this purpose, these actions being absolutely
the demonstrations of this unique thought.

"Habits, acquired in view of certain realizations, ought to be dropt from
the moment the purpose is accomplished, or that it is weakened."
