In today’s generation, great philosopher are known throughout the world.”PHILOSOPHER” a person who studies ideas about knowledge,truth, the nature and meaning of life. “One should hesitate in all things except those which are proved by living reason”. What do you think this means? Do you think something in this phrase want to deliver or say? Well I think this wants to say that we should hold back in doubt in anything except or only when it is a prove by reason which you can see because having doubt with everything is about giving your full attention to it. You shouldn’t doubt on those things until you realize that it is true.

           John of Salisbury was born at Old Sarum (the former site of Salisbury) in England between 1115 and 1120. Specific knowledge of his family background and early life is scant; something is known of a brother, Richard, and a half-brother, Robert, both of whom held offices within the English church. John probably received an early education at Salisbury and then at Exeter. The first date safely associated with him is 1136, when he traveled to Paris to study at Mont-Sainte-Geneviève. In a famous autobiographical passage in the Metalogicon John narrates his twelve years of education, an important source for understanding French higher instruction in this period.

        John of Salisbury (1115/20–1180) was among the foremost philosophers of the so-called twelfth century Renaissance,  he spent most of his life as an active servant of the church. An associate of Archbishop Thomas Becket of Canterbury during his dispute with King Henry II of England, John eventually was raised to the office of Bishop of Chartres. John’s thought has been characterized as “humanistic”, since he valorizes the dignity of humanity and of nature generally: The latter is intelligible and may be understood through the application of natural reason. “HUMANISTIC” are terms in psychology relating to an approach which studies the whole person, and the uniqueness of each individual also sometimes the humanistic approach is called phenomenological.This means that personality is studied from the point  of view of the individual’s subjective experience. Yet John admitted that severe impediments exist to the attainment of wisdom. Throughout his writings,he professed to follow the moderate skepticism of cicero and the new academy .John says that probable truth,always subject to re evalution and revision. The general tenor of his philosophy is reflected in his advocacy of moderation and his emphasis on nature as a normative guide to earthly fulfillment

We all have to be what we are like John of salisbury, He has been characterized as an humanistic because he valories the dignity of society not for himslef only but for the sake of the people surronds him.
