Abstract
Jean Piaget's theory of human mental development mirrors many issues related to human. According to this theory, one's view of himself, nature/universe and God is changing. According to this theory, which is basically divided into four main periods and subtitles, the thinking skill of man changes according to age, physical development, education and society. These differences affect the way individuals obtain information. Individuals who acquire knowledge with an emotional intuition before the age of seven acquire information through an inductive way, in other words, through concrete intuition, through concrete processes, experimentation and observation, in parallel with the development of the brain and senses. At the age of eleven and after which intellectual reasoning develops, information becomes abstract and information is obtained through abstract intuition based on theories, hypotheses and assumptions. In the love experience of Rumi, a mystical thinker, knowledge is obtained only with emotional intuition, and it is claimed that the only way to obtain information is love-based emotional intuition. In this love-based emotional intuition, the ways of obtaining concrete/experimental and abstract/rational knowledge requiring high level mental skills are rejected and these methods are said to be 'devil’s work'. In this study, Rumi's approach to human, universe and God in this one-sided and emotional way is criticized and its inconsistency is revealed.
