The exploration of meaning, connection, mystery, and the self without making supernatural claims. Instead of turning mystery into certainty, you let reality push back. Claims are sorted as empirical, rational, or irrational, not as insults, but as philosophical categories.
Agnostic spirituality is a personal, science-first exploration anchored by alignment with reality.
In practice, agnostic spirituality embraces what is empirically and rationally true, holds speculative ideas with humility, and lets go of disproven claims as truth. Some ideas may still be kept for symbolic, cultural, emotional, or pragmatic reasons, but they are not treated as public truth.
Within TST, Agnostic Spirituality is secular spirituality expressed through the Material-Spiritual Framework.
