World History

Etymology
The word history comes from the root weid- "know" or "see".
Ancient Greek ἱστορία means "inquiry" or "knowledge from inquiry", from ἵστωρ (hístōr) "judge" (from the Proto-Indo-European agent noun wid-tor: "one who knows"). It was in that sense that Aristotle used the word in his Περὶ Τὰ Ζῷα Ἱστορίαι (Perì Tà Zôa Ηistoríai "Inquiries about Animals"). The ancestor word ἵστωρ is attested early on in Homeric Hymns, Heraclitus, the Athenian ephebes' oath, and in Boiotic inscriptions (in a legal sense, either "judge" or "witness", or similar).
It was still in the Greek sense that Francis Bacon used the term in the late 16th century, when he wrote about "Natural History". For him, historia was "the knowledge of objects determined by space and time", that sort of knowledge provided by memory (while science was provided by reason, and poetry was provided by fantasy).
