Contrary to the popular idea of "finding yourself," existentialist philosopher Simone de Beauvoir argued that authenticity is not a pre-existing self to be uncovered. Instead, it's a continuous process of creating and renewing oneself through intentional choices and actions, much like a poet composes a poem.
While "big ideas" are powerful, Hume cautioned against the intellectual arrogance of adopting a single theory as a universal explanation. Over-relying on one framework, from social change models to diet fads, leads to error. The biggest ideas are still only small parts of a much larger, more complex reality.
Simone de Beauvoir's philosophy rejects a purely individualistic view of authenticity. It exists in the tension between being for oneself and being for others. Leaning too far into self-interest leads to egoism, while excessive people-pleasing erodes the self. Authentic relationships respect the full humanity and freedom of others.
Hume argued against "rationalism"—the belief that pure reason alone can solve complex problems. This approach, which looks brilliant on paper, often fails in practice (e.g., modernist architecture, utopian politics). A wiser path combines reason with experience, grounding decisions in what works in reality, not just in theory.
The direct pursuit of happiness traps us on a "hedonic treadmill," constantly seeking the next rush. Beauvoir suggests happiness is not a goal but a side effect. It emerges from living authentically: taking responsibility, pursuing meaningful goals, taking risks, and building deep connections with others.
While modern Stoicism is popular, Hume found its core tenet—valuing only what's in your control and suppressing emotion—to be impossible and undesirable. Attempting this level of detachment dampens positive emotions along with the negative, rendering life inert. Adopt useful Stoic tactics without embracing the emotionless ideal.
