Learning a second language reshapes cognition in measurable ways — expanding the conceptual palette through exposure to categories, distinctions, and framings absent in the first language, while developing the cognitive flexibility to shift between different systems of meaning. The research on bilingual cognitive advantages (enhanced executive function, delayed dementia onset) is more contested than its popular reception suggests, but the phenomenological evidence of language learning as worldview expansion is consistent and profound. Each language carries a different attentional structure, a different set of salient distinctions — a different theory of what matters.
