Desiderius Erasmus Roterodamus was a Dutch philosopher and Christian scholar who is widely considered to have been one of the greatest scholars of the northern Renaissance.

Among humanists he enjoyed the sobriquet "Prince of the Humanists", and has been called "the crowning glory of the Christian humanists". Using humanist techniques for working on texts, he prepared important new Latin and Greek editions of the New Testament, which raised questions that would be influential in the Protestant Reformation and Catholic Counter-Reformation.

John Major (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 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, science, politics, Church, and international law 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.

Giovanni Pico della Mirandola was an Italian Renaissance nobleman and philosopher. He is famed for the events of 1486, when, at the age of 23, he proposed to defend 900 theses on religion, philosophy, natural philosophy, and magic against all comers, for which he wrote the Oration on the Dignity of Man, which has been called the "Manifesto of the Renaissance", and a key text of Renaissance humanism and of what has been called the "Hermetic Reformation". He was the founder of the tradition of Christian Kabbalah, a key tenet of early modern Western esotericism. The 900 Theses was the first printed book to be universally banned by the Church.
