David Hume's Mental Struggle and Recovery
📌 At age 18, David Hume suffered from the "disease of the learned," experiencing an inability to concentrate, zero motivation, and deep depression.
⚕️ His recovery was achieved not through contemporary medical treatments (like hysteria pills and wine) but by re-engineering his mind using scientifically validated learning tools.
🧠 Hume went on to overturn Western philosophy and died one of the calmest and happiest men in history despite his controversial atheism.

Autodidacticism and Curated Learning
🏛️ Hume criticized the rigidity of institutional education, famously stating that there is nothing to be learned from a professor not found in books, emphasizing the need for independent thinking alongside reading.
📚 He practiced autodidacticism by creating his own curriculum: reading referenced books and actively seeking out texts that questioned the validity of established education systems.
🔍 This approach revealed that educational systems have historical biases and control mechanisms that may not serve individual benefit.

Self-Inquiry and Eastern Philosophy Influence
🌏 Hume potentially encountered principles of Buddhism or Advaita Vedanta while in France, where Jesuit monks were translating ancient Eastern texts.
🧘 The core concept encountered was Advaita's non-duality ("one not two"), which helped frame his realization that the self might not be a concrete entity.
🤔 Self-inquiry questions (like "To whom is this thought occurring?") lead to metacognition, suggesting the anxious or depressed self cannot be located under skeptical inquiry, as it is merely a "bundle of perceptions."

Combating Cognitive Fatigue with Learning Techniques
🛑 Hume's depression was partly due to forcing his mind into unwanted shapes using rote repetition, which studies suggest reduces critical thinking faculties.
🔄 Upon recovery, Hume intentionally practiced interleaving (deliberate rotation between different subjects/books, like Tacitus, Butler, and Virgil) instead of cramming.
🧠 Interleaving creates more retrieval paths and neurogenesis by keeping the brain engaged, preventing the cognitive fatigue associated with grinding on one subject for hours.

The Importance of Socialization and Experience
🗣️ Influenced by authors like Shaftesbury, Hume learned that a true intellectual cannot be a hermit; he became known as "Le Bon David" (the good David) for his sociability.
🎲 Learning skills flourish when information is pulled out and discussed in multiple contexts (socializing, playing games, experiencing art/culture).
🧘 Engaging socially exercises multiple levels of the brain, leading to a deeper level of memory and resilience against anxiety caused by intense study.

Key Points & Insights
➡️ Hume recovered from debilitating depression by rejecting rote learning and adopting curated reading and self-inquiry methods.
➡️ To counter cognitive fatigue, implement interleaving: deliberately switch between different subjects or modes of learning (e.g., reading, writing, listening) to build robust neural pathways.
➡️ Combat feelings of an ephemeral or anxious self by practicing self-inquiry based on Eastern philosophy principles, realizing the self is a "bundle of perceptions" that can be changed.
➡️ Social interaction regarding learned material is crucial; avoid academic isolation as it leads to stagnation and limits memory consolidation.
