『エチカ』、第III部、感情の定義27

The causes of these emotions we have set forth in III. li. note, and in III. liii., liv., lv. and note. Concerning the free decision of the mind see II. xxxv. note. This is perhaps the place to call attention to the fact, that it is nothing wonderful that all those actions, which are commonly called wrong, are followed by pain, and all those, which are called right, are followed by pleasure. We can easily gather from what has been said, that this depends in great measure on education. Parents, by reprobating the former class of actions, and by frequently chiding their children because of them, and also by persuading to and praising the latter class, have brought it about, that the former should be associated with pain and the latter with pleasure. This is confirmed by experience. For custom and religion are not the same among all men, but that which some consider sacred others consider profane, and what some consider honourable others consider disgraceful. According as each man has been educated, he feels repentance for a given action or glories therein.
