"To doubt everything or to believe everything are two equally convenient solutions; both dispense with the necessity of reflection"
About this Quote
Calling them “equally convenient” is the tell. Convenience is not an epistemological virtue; it’s a psychological one. Pournelle is pointing at the seduction of shortcuts: certainty as a time-saver, cynicism as a shield. “Dispense with the necessity of reflection” frames reflection as labor - not a vibe, not a personality trait, but an obligation. The line suggests that what’s really being avoided isn’t information but responsibility: if you pre-decide that nothing can be trusted, you’re never accountable for what you ignore; if you pre-decide that everything is true, you’re never accountable for what you repeat.
As a journalist writing in late-20th-century America, Pournelle is also bristling at media and political ecosystems that reward instant alignment. His point reads like an early warning for our current attention economy, where “I’m skeptical of everything” and “I’m just asking questions” can be as lazy as “I saw it online so it must be real.” The sting is that reflection isn’t just harder; it’s slower, and slowness is what convenience is designed to erase.
