Sympathy: Crossing Into Another Mind

The chapter's central question

Hume's sympathy is a broader communication principle than today's warm sympathy. We get an idea of ​​another's mind from the facial expressions and situations of others, and when that idea becomes vivid through similarity, intimacy, and causality, it feels like a real impression. Fear and pride, as well as joy, are socially contagious.

Read the complete essay

The warmest and most dazzling concept in Hume's philosophy is 'Sympathy'. Humans are not isolated islands. Just as when you pluck the strings of one stringed instrument, the strings of other instruments nearby vibrate slightly, the human heart instinctively resonates with the joys and sorrows of others.

When we see a child bleeding after falling on the street, we do not calculate ethical obligations in our heads to help them. Because the moment I see the child's distorted expression, the same flame of pain burns in my heart.

� Hume asserts: 'Morality is not a set of rational rules, but a warm moral sentiment that makes one feel heartbroken by the situation of others and happy by good deeds.' Without a heart that can empathize, even genius intelligence becomes nothing more than a tool for a sociopath.

Context and nuance

Hume attempted to observe the human mind in experience rather than in its abstract essence. In 『Treatise on Human Nature』, passion is a central element in which impressions, ideas, imagination, beliefs, and social sympathy are intertwined to create actions and moral judgments. Reason is important, but it alone cannot create purpose.

Just because empathy is natural does not mean that prejudice automatically disappears. Emotions from people who are close to us are more easily conveyed than to people who are far away. Therefore, moral judgment requires a ‘general perspective’ that takes a step back from personal preferences. Hume's emotionalism involves a social discipline that corrects one's perspective rather than an ad hoc fetishization of feelings.

Do not oversimplify it this way

The sentence ‘Reason is a slave to passion’ does not mean that reason is useless or that facts can be ignored. Reason corrects the direction of desire by informing us of facts, causes, and means. However, Hume's point is that simply knowing the facts does not automatically give us what we should want and the motivation to act.

Philosophy in life

Have you ever had a time when you knew in your head, ‘I have to study right now, I have to exercise,’ but you didn’t want to lift a finger because your heart didn’t move?

Empathy muscle training: Today, look into the eyes of people who are in a completely different situation than you (delivery driver, cleaning worker, exhausted co-worker) and give them a warm, grateful look.
