Abstract
There is an agreement between critics about the idea that Renaissance is the origin, or at least one key moment, of modern subjectivity. The recover of classical ideals brought together, at the same time, the statement of new concepts, or their intensification, as the idea of individual subject. It is a topic too that some key philosophical schools reappear at the Renaissance and that they have a very important paper in the humanities and science renewal, as the sceptical school. In our judgement, some renaissance authors combine both notions in a productive and relevant way to our contemporary thought, on of them, Michel de Montaigne, will be the subject of our meditation
