Aletheia (Ancient Greek: ἀλήθεια) is truth or disclosure in philosophy. It was used in Ancient Greek philosophy and revived in the 20th century by the philosopher Martin Heidegger.
Aletheia is variously translated as "unconcealedness", "disclosure", "revealing", or "unclosedness". It is also sometimes treated as "truth", but Heidegger himself later argued against this. The literal meaning of the word ἀ–λήθεια is "the state of not being hidden; the state of being evident." It also means factuality or reality. It is the opposite of lethe, which literally means "oblivion", "forgetfulness", or "concealment" according to Pindar's First Olympian Ode.
Aletheia, the name of a Greek goddess (also known as Veritas, the Roman goddess of truth), is the daughter of Zeus, while Aesop's Fables state she was crafted by Prometheus.
