Who is Bernardinus Telesius?December 14, 2020
Bernardinus Telesius (1509-1588), a Renaissance scientist, was born in Cosenza, in southern Italy. He studied in Milan, Rome and Padua.
He worked in classical culture, philosophy and science. Masterpiece: De Rerum Natura Iuxta bears the name Propria Principia (On the Nature of Things According to Its Principles). As a natural scientist-natural philosophy study person, he begins by criticizing the Aristotelianism of scholastic.
For this reason he assumed the chairmanship of the great Southern Italian Movement, which was created to protest those who accepted the authority of abstract reason. According to this, it is not possible to reach a truth with only rational operations, on the contrary, it is necessary to resort to the senses; It is necessary to do our research on the data provided by the senses: According to him, all of the correct information is literally based on sense perception. However, the theory of sense perception draws attention as a reconsideration of the views in Aristotle’s De Anima (On the Spirit). In addition, the question of exactly how to form correct information on pure sense perception does not seem to find a complete answer in their explanations.
According to Telesius, it is inevitable to resort to the senses in order to reach the truth, and correct knowledge is based on sense perception.
It is thought that Telesius deserves this title because he insists on the need to switch from the methods of authority and abstract reason to the experiment method and is accepted as a symbol of the transition period to individual responsibility. His following sentence summarizes his view of natural science: “The structure of the world and the size of the objects in it and the nature of the world cannot be investigated by reason, as in the past, but can be understood by means of observation. However, his understanding of observation partially differs from today’s modern understanding of observation: According to him, observation is a far more comprehensive mental process than the recording of data, and it also includes analogical thinking. Bacon, the great thinker of the end of the Renaissance, calls himself “the first of the modern”, as he regards the method of observation as superior and necessary to all methods in order to obtain the knowledge of the natural world and again opposes the scholastic authority.
Telesius was one of the pioneers of philosophical empiricism, insisting on the transition from authority and abstract methods of reason to the method of experiment.
