Adiaphora
（重定向自Adiaphorism）
Adiaphoron (plural: adiaphora from the Greek ἀδιάφορα "indifferent things") is a concept of Stoic philosophy that indicates things outside of moral law—that is, actions that morality neither mandates nor forbids.
In Pyrrhonism, "adiaphora" indicates things which cannot be logically differentiated.
