From Sadness Toward Active Joy

The chapter's central question

Vague resentment imagines a person as the free cause of evil, but proper understanding sees the behavior in a chain of characters, relationships, institutions, and previous causes. The more causes an idea contains, the more I move from being a mere victim of an emotion to a cause that constitutes the next action. Rather than eliminating emotions, understanding changes our relationship with them.

So how can we escape emotional slavery? Spinoza's proposal shines brightly in Part 5, Theorem 3 of 『Ethica』.

'An emotion that is a passion ceases to be a passion the moment we form a clear idea about it.'

The reason I go on a rampage when someone hurts me is because I don't see the entire cause-and-effect relationship of the incident and see it through a distorted lens of 'that horrible guy intentionally harassed me.' But take a step back and clear the lens of your thoughts.

'That person also spit out such aggressive words because of his sense of entitlement. 'His family environment and the stress he received today caused him to act like that.'

The moment you clearly understand that everything in nature is intertwined in an inevitable chain of cause and effect, the burning flames of hatred are replaced by calm compassion and intelligent peace. Those who understand will not be hurt.

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.

The expression ‘he who understands is not hurt’ exaggerates Spinoza. Even after you understand, your body and memories may ache. A more accurate change would be a weakening of the inevitability that hate is the only possible response to hurt. People who see the cause may have more possibilities for action, such as distancing, solidarity, and system improvement.

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.
