He argues that there are many things that he accepted as truth in his childhood. Descartes refuted his childish and youthful beliefs and sought to build his ideas afresh. He used a methodological approach to handle issues that nagged his mind. He is quoted as saying that “some thoughts within him were as due to his power of thinking.” In applying these thoughts in ideas of notion, he was able to distinguish them from others.
