- Purpose of life
- Agnosticism assigns none, and says so plainly: no purpose can be read off a universe whose author, if any, is unknown. Meaning is therefore built, not found — in work, love, inquiry, and whatever a person judges worth their life; most agnostics take this framework from humanism.
- Ethics
- Typically secular — humanism, virtue ethics, or pragmatism.
- Afterlife
- Unknown. Survival of death is neither affirmed nor denied; most agnostics judge the evidence for an afterlife weak — Hume's essay on immortality is the classic statement — and live as if this life is the one they are sure of.
- Key practices
- None are prescribed — there is no agnostic prayer, diet, or calendar. The habits agnostics describe are ordinary intellectual ones: reading, questioning, revising; the honest answer is that agnosticism shapes how one thinks, not how one's day is structured.
