Who is Acontius Jacobus?

He is an Italian thinker.

Aristotle applied his logic to theology with a new interpretation. He was born in Taranto at the beginning of the 16th century, when we don’t know the exact year. There is no exact information about his life, early youth, family and education.

According to some sources, Acontius, like his contemporary sages, went on adventurous trips and emigrated from Italy after being affected by the reform events. He settled first in Bale and then in Strasbourg, where he published most of his works. Then he went to England.

There, he was given an engineering salary at the queen’s command due to the book he wrote on war technique. According to Acontius, a reformist Protestant, logic is the doctrine of finding the truth and telling others. The main basis of this teaching is method. The method is “the way of seeking the truth, following the acquisition of the data that provides the information, and transferring the gained information to others.” It is the method that provides information, shapes it and gives it integrity and validity. There are two ways to obtain information: one is to perceive the events, which is the first instrument, and the other is to know the cause and effect connection between the events.

The method that controls these operations has two parts. In the first, there is deep research, reaching the source and constituent elements of the events, and in the second, “showing”, revealing and explaining. Deep research is a mathematical analysis that helps to comprehend causes and results and to find the connection between them.

This process also applies to innate information. Acontius applied the method of analysis, which can be used in all fields, in his book “Stratagematum Satanae Libre Octo” (“Devil’s Plays in Eight Books”), which includes theology topics. Thus, it finds the cause-effect relationship.

Acontius’s influence on those who came after him lasted a long time. Those who adopted his ideas claimed that he was a creative, independent, superior wise, and brought innovations in theology and logic. In particular, they defended the view that the Middle Ages left the heavy, boring narrative of the written language and had a fluent, easy-to-understand and plain style. Those who opposed him, arguing that he had reached an excess in the field of theology, that he had broken the usual way and acted against general principles, criticized his works with a bitter language. Despite all the positive and negative criticisms, Acontlus is considered one of the first practitioners of the contemporary analytical method in the field of logic.
