The designation "Renaissance philosophy" is used by scholars of intellectual history to refer to the thought of the period running in Europe roughly between 1400 and 1600 (the dates shift forward for central and northern Europe and for areas such as Spanish America, India, Japan, and China under European influence). It therefore overlaps both with late medieval philosophy, which in the fourteenth and fifteenth centuries was influenced by notable figures such as Albert the Great, Thomas Aquinas, William of Ockham, and Marsilius of Padua, and early modern philosophy, which conventionally starts with René Descartes and his publication of the Discourse on Method in 1637. Philosophers usually divide the period less finely, jumping from medieval to early modern philosophy, on the assumption that no radical shifts in perspective took place in the centuries immediately before Descartes. Intellectual historians, however, take into considerations factors such as sources, approaches, audience, language, and literary genres in addition to ideas. This article reviews both the changes in context and content of Renaissance philosophy and its remarkable continuities with the past. Continuities The structure, sources, method, and topics of philosophy in the Renaissance had much in common with those of previous centuries. Structure of philosophy Particularly since the recovery of a great portion of Aristotelian writings in the twelfth and thirteenth centuries, it became clear that, in addition to Aristotle's writings on logic, which had already been known, there were numerous others roughly having to do with natural philosophy, moral philosophy, and metaphysics. These areas provided the structure for the philosophy curriculum of the emerging universities. The general assumption was that the most 'scientific' branches of philosophy were those that were more theoretical and therefore more widely applicable. During the Renaissance too, many thinkers saw these as the main philosophical areas, with logic providing a training of the mind to approach the other three. Sources of philosophy A similar continuity can be seen in the case of sources. Although Aristotle was never an unquestioned authority (he was more often than not a springboard for discussion, and his opinions were often discussed along those of others, or the teaching of Holy Scripture), medieval lectures in physics consisted of reading Aristotle's Physics, lessons in moral philosophy consisted of examinations of his Nicomachean Ethics (and often his Politics), and metaphysics was approached through his Metaphysics. The assumption that Aristotle's works were foundational to an understanding of philosophy did not
