George berkeley (1685-1753) was an Irish Idealist philosopher. Best known for his advocacy of immaterialism, he went from epistemological studies to develop analysis of metaphysical themes, philosophy of science, philosophy of mathematics, philosophy of religion, economics, politics, and morals. He also believed that the foundations of mathematics cannot be understood, just as we cannot understand the foundations of faith, and if we believe in mathematics, the greater belief we should have in religious truths.
In 1707, he received the title of Master of Arts (M.A.); develops the immaterialist philosophy, partially recorded in two notebooks, now known as philosophical commentaries; publishes two brief mathematical treatises entitled Arithmetic and Miscellanea Mathematica. Wrote The analyst between 1732 and 1734. In this work he criticized Newton's differential and integral calculus. Also wrote A defense of free thinking in mathematics.
Still in 1734, is named bishop of Cloyne, in Ireland. During the famine and plague epidemic that occurred between 1737 and 1741, Berkeley devoted himself to the sick, trying to cure them with tar water. On the subject, he wrote a work called Siris in 1744. Also around this time he wrote The Questioner, where he reflects on economic and social issues. In 1752, old and sick, Berkeley resigned the episcopate and retired to Oxford, where he died.
