Human Bondage: Captured by Another's Expression

The chapter's central question

Passive emotions are a state in which you are not a sufficient cause of change and are partially driven by external causes. If other people's praise increases your power and criticism immediately lowers it, your emotional condition is tied to the other person. Insufficient ideas see only part of the event and fill in the entire cause with imagination, which increases hatred and jealousy.

Read the complete essay

The title of Part 4 of 『Ethica』 is ‘On the Slavery of Man, or the Power of Passion’. Slavery literally means slavery.

Why can't we be free? This is because the cause of the emotions I feel is not within me, but is tied to ‘someone outside’. When my boss praises me, I feel happy and feel like I'm flying to heaven, but when my boss frowns, I wander through hell all day. This is ‘Passio’. I am being dragged around with the cockpit of my emotions in someone else's hands.

In particular, 'jealousy (Invidia)' and 'hatred (Odium)' are the most destructive passive passions that eat away at conatus. The feeling of stomachache when I see others doing well comes from the illusion that my own ability to exist has become shabby. The more I hate the other person, the more my conatus is bound and suffocated by the other person's shadow.

Context and nuance

Spinoza's 『Ethica』 places God, nature, humans, emotions, and freedom in one system through the geometric form of definitions, axioms, theorems, and proofs. Emotions are not exceptions to the laws of nature, but rather the idea of ​​change and the increase or decrease in human capacity for action.

Interpreting servitude as a mental deficiency of the individual moves away from Spinoza's naturalism. Human beings are by nature highly dependent on external causes and cannot be completely independent. Increasing your degree of freedom means denying dependence, but instead recognizing the relationships that weaken you and creating common conditions that increase your strength.

Do not oversimplify it this way

Spinoza’s ‘understanding’ should not be used as a technique to rationalize others’ mistakes or endure hurts. Understanding the causes can help you set boundaries more accurately and even change your environment. We must also avoid intellectual omnipotence, which assumes that one bright thought immediately erases strong emotions. Spinoza says that an emotion can only be suppressed by a stronger opposing emotion.

Philosophy in life

Have you ever felt black inside and lost all strength in your body all day because you hated and were jealous of someone?

Sublimation of emotions through understanding: From the perspective of the person who made me angry, write down three objective reasons why he had no choice but to engage in such deficient behavior.
