Etymology

It is borrowed from New Latin ontologia, a word unknown to classical Greek and Latin.[2][3][4] The revised TLF notice calls the French word a calque of the New Latin term and finds it first in 1613, in Greek letters in Goclenius's Lexicon philosophicum and in Latin form in Lohardus's Theatrum.[2] Rey dates Goclenius's Greek form to 1603,[4] the TLFi and the Robert dictionaries cite Clauberg's Metaphysica of 1646,[3][5][6] and Bloch and Wartburg wrongly credit the coinage to Christian Wolff.[7][2]

The element ⟨ont-⟩ is the stem of Ancient Greek ὤν (ṓn, “being”), genitive ὄντος (óntos), the present participle of εἰμί (eimí, “to be”), and the second element is -logie.[2][4][8][9] Rey notes that the root of the Greek verb is also found in Latin est (“is”).[4]

Earliest recorded meaning

It is first found in 1692 in La Placette's Traité de l'orgueil for the part of philosophy that studies the most general properties of being; the same year Le Clerc used it in a letter to Locke (20 January 1692).[2][3] The Bibliothèque universelle explained that Le Clerc called Ontologie what was commonly called metaphysics, since that science deals with being in general.[2]

Semantic evolution

In philosophy the word names the part of metaphysics that deals with “being as being”, in Aristotle's phrase.[4][6] The Journal des savants of 1696 describes a metaphysics divided into an ontology and a pneumatology, the latter treating God, the angels and the human mind.[2][10]

From 1821 the physician Broussais used ontologie for the doctrine he attacked, which treated diseases, fevers in particular, as entities existing in themselves; he called it ontologie médicale.[2][4] After the 19th century this medical sense survives only in historical writing.[2]

The adjective ontologique (1765, in the Encyclopédie) was formed by a change of suffix, perhaps after Goclenius's ontologikê;[4] Bloch and Wartburg date it to 1740.[7] ontologiste (1824) and ontologisme (1868) followed.[4] English has ontology from the 1660s, from the same New Latin word.[11]
