Ockham's second thesis was the principle of parsimony: also known as Ockham's razor. This developed a new form of logic, based on an empiricist theory of knowledge. "While Scholastic in setting," as David Lindberg writes, it was "thoroughly modern in orientation. Referred to as the "via moderna", in opposition to the "via antiqua" of the earlier scholastics, it has been seen as a forerunner of a modern age of analysis." Other, even more skeptical thinkers in the mid-14th century included John of Mirecourt and Nicholas of Autrecourt. It has been suggested that the new philosophy of nature that emerged from the rise of Skepticism following the Condemnations, contained "the seeds from which modern science could arise in the early seventeenth century."
