internalism
Internalism is the philosophical creed asserting that truth or meaning resides solely in one’s own internal, invisible certificates, ignoring external evidence while insisting, 'My mind decrees it.' It boasts the highest form of self-esteem as a rationale but harbors the exquisite pitfall of being empirically unverifiable. When challenged, adherents retort that any objection merely reveals the challenger’s ignorance of their inner workings, flinging debate beyond the reach of shared reality. It’s a seductive doctrine promising self-sufficiency yet delivering an endless echo chamber of certitude.
