“There are words that we often use without paying attention to their deep meaning; we say: “This is contrary to the inner feeling, humanity is indignant at this, the heart refuses to believe this.” What feeling gave rise to these expressions? It is not a consequence of reasoning, it is not a consequence of education—in a word, it is not a consequence of reason. You see the execution of a criminal; your reason convinces you that it is necessary, but it would be contrary to your inner feeling not to grieve for it. Reason tells you that you must kill your enemy in the heat of battle, but ask the bravest warrior how he feels when he walks across the battlefield after the battle? After all, these wounds were necessary, these sufferings are a necessary consequence of a just battle, why does his heart tremble, why does a trembling pass through his body, why does his humanity become indignant? Why is it sometimes that your very heart is struck by some passion, and your reason assures you that you can indulge in it safely, but some other inner feeling holds you back?
