Pronunciation
Forms
στοχᾰστῐκός (stokhastikós) m (feminine στοχᾰστῐκή, neuter στοχᾰστῐκόν); first/second declension[1]
Etymology
It is formed from Ancient Greek στοχάζομαι (stokházomai, “to aim at; to guess”) + -τικός (-tikós).[2][3] The verb comes from στόχος (stókhos, “aim, target”).[1]
Earliest recorded meaning
It is first found in Plato: in the Gorgias rhetoric is said to need a mind good at guessing, and in the Philebus the art of conjecture is set against the exact arts.[4][5][6]
Semantic evolution
Aristotle used it of what aims at a goal: virtue aims at the mean, and good deliberation at the best.[4][5] Philodemus contrasted the conjectural sciences with the fixed ones, and the Stoics and Galen spoke of conjectural arts and a conjectural diagnosis.[4] Marcus Aurelius used it for consideration for the wishes of friends, and in rhetoric it named questions of conjecture.[4][2]
Modern Greek στοχαστικός (stochastikós) continues the ancient word in the sense “thoughtful, reflective”.[3][7] A second, learned στοχαστικός of statistics, “random”, was made anew from the stem of στοχάζομαι in its Hellenistic sense “to calculate”.[3][7]
