What this quote means

This quote highlights the difference between formal education and personal learning. Salinger, although educated, calls himself 'illiterate' to emphasize that diplomas don't make culture. What matters is curiosity and the will to learn on one's own. Reading widely is opening up to the world, developing one's thinking, without being limited to academic frameworks. It's a praise of self-teaching and the thirst for knowledge.
