A person who studies the nature of truth or practices alethiology; a truth philosopher or truth researcher.
Aletheia (truth) + -ologist (one who studies). Rare but precise term for philosophers and thinkers specializing in truth-related inquiry.
An alethiologist is a truth specialist—and the rarity of the term reflects how even philosophers often don't have dedicated labels for their specific inquiry areas, yet the word perfectly captures those obsessed with understanding truth itself.
