学問にせよ何にせよ，人類は先人から得た知識を蓄積し，その上にさらなる知識を付け加えるという形で文明を進歩させてきた．このことを西洋では to stand on the shoulders of giants 「巨人の肩の上に立つ」と表現する．
以下は「1人の巨人の左肩（のみ）に乗る小人」という状況のエッチングで，厳密には "a dwarf on a shoulder of a giant" というべき状況だが，この辺りはご愛敬で．
さて，この慣用句は OED の shoulder, n. のもとに挙げられているのだが，実は2022年3月の OED の定期更新の際に新たに加えられたホヤホヤのエントリーなのである．この新エントリーについて，OED の広報記事 "Content warning: may contain notes on the OED March 2022 update" が次のようにコメントしている．
A new phrase entry in shoulder examines the use of to stand on the shoulders of giants to refer to the process of building on the discoveries and achievements of great predecessors, first recorded in the early seventeenth century in a variation on the proverb a dwarf (or child) standing on the shoulders of a giant sees farther than the giant, itself based on a twelfth-century Latin phrase attributed to Bernard of Chartres.
