John of Salisbury in 1159 wrote:
Bernard of Chartres used to compare us to dwarfs perched on the shoulders of giants. He pointed out that we see more and farther than our predecessors, not because we have keener vision or greater height, but because we are lifted up and borne aloft on their gigantic stature.
This was in his work called Metalogicon. The Metalogicon was about the value of the Trivium (Grammar, Rhetoric, Logic). It consists of four sections that defend the Trivium against those felt that Grammar and Rhetoric were not important to the study of Logic. John would not have known Bernard, who died in the 1120s (John was a child then, going to grammar school in England). He did, however, study Rhetoric and Logic at Chartres under one of Bernard's disciples, Richard l'Evêque.
Although John attributes this to Bernard of Chartres, while John was at Chartres he also studied under William of Conches. John should have been unaware that William, in his 1123 commentary on the Institutiones grammaticae of Priscian, wrote:
The ancients had only the books which they themselves wrote, but we have all their books and moreover all those which have been written from the beginning until our time.… Hence we are like a dwarf perched on the shoulders of a giant. The former sees further than the giant, not because of his own stature, but because of the stature of his bearer. Similarly, we see more than the ancients, because our writings, modest as they are, are added to their great works.
John of Salisbury referred to himself as Johannes Parvus, "John the Little"; parvus can mean "little" or "small." he does not indicate in his writings that he was physically sort. Perhaps this was a humble moment in which he claimed to be not a giant.
A commentator on the Talmud, the Jewish Isaiah di Trans (c.1180 - c.1250) wrote:
For I heard the following from the philosophers, The wisest of the philosophers was asked: "We admit that our predecessors were wiser than we. At the same time we criticize their comments, often rejecting them and claiming that the truth rests with us. How is this possible?" The wise philosopher responded: "Who sees further a dwarf or a giant? Surely a giant for his eyes are situated at a higher level than those of the dwarf. But if the dwarf is placed on the shoulders of the giant who sees further? ... So too we are dwarfs astride the shoulders of giants.
Anyway, the phrase caught on long before Isaac Newton wrote his letter to Robert Hooke. But back to John of Salisbury. Besides defending the Trivium and the verbal arts, he had some strong opinions about things that could be proven, and some strong arguments about the medical profession of his day. I'll talk about those tomorrow.
