John Major (or Mair) (also known in Latin as Joannes Majoris and Haddingtonus Scotus) (1467–1550) was a Scottish philosopher, theologian, and historian who was much admired in his day and was an acknowledged influence on all the great thinkers of the time. A very renowned teacher, his works were much collected and frequently republished across Europe. His "sane conservatism" and his sceptical, logical approach to the study of texts such as Aristotle or the Bible were less prized in the subsequent age of humanism where a more committed and linguistic/literary, approach prevailed. His influence in logic (especially the analysis of terms), science (impetus and infinitesimals), politics (placing the people over kings), Church (councils over Popes), and international law (establishing the human rights of "savages" conquered by the Spanish) can be traced across the centuries and appear decidedly modern, and it is only in the modern age that he is not routinely dismissed as a scholastic. His Latin style did not help – he thought that "it is of more moment to understand aright, and clearly to lay down the truth of any matter than to use eloquent language". Nevertheless, it is to his writings, including their dedications, that we owe much of our knowledge of the everyday facts of Major's life – for example his "shortness of stature". He was an extremely curious and very observant man, and used his experiences – of earthquakes in Paisley, thunder in Glasgow, storms at sea, eating oatcakes in northern England – to illustrate the more abstract parts of his logical writings.
John Major (or 'Mair') was born about 1467 at Gleghornie, near North Berwick where he received his early education. It was at nearby Haddington, East Lothian, Scotland, where he attended grammar school. He was probably taught by the town schoolmaster George Litsar, who was, according to Major "although a circumspect man in other ways, more severe than was just in beating boys". If it had not been for the influence of his mother, Major says he would have left, but he and his brother stayed on and were successful. According to him, Haddington was "the town which fostered the beginning of my studies, and in whose kindly embrace I was nourished as a novice with the sweetest milk of the art of grammar". He says he stayed in Haddington "to a pretty advanced age" and he remembers the sound of the King James III's bombardment of the nearby castle of Dunbar, which was in 1479. He also remembers the comet which was supposed to have foretold the King's defeat at Sauchieburn which was in 1488. However, it was in 1490, he reports, that he "first left the paternal hearth". In 1490, probably under the influence of Robert Cockburn, another Haddington man, destined to be an influential bishop (of Ross and later of Dunkeld), he decided to go to Paris to study among the great numbers of Scots there at the time.
