He affirmed that experiments should be used to verify a theory, testing its consequences and added greatly to the development of the scientific method. Albertus Magnus (c. 1193–1280): patron saint of scientists in Catholicism who may have been the first to isolate arsenic. He wrote that: "Natural science does not consist in ratifying what others have said, but in seeking the causes of phenomena." Yet he rejected elements of Aristotelianism that conflicted with Catholicism and drew on his faith as well as Neo-Platonic ideas to "balance" "troubling" Aristotelian elements.
