The fuzzy logictheory possesses a more precise capacity to explain and analyze concepts and phenomena and also a spectral reading of phenomena thatuses the binary numbers of 0 and 1 as the extreme points of reality and accepts that there are infinite points of reality between the two of them; therefore, in order to more precisely and comprehensively understand reality, one must have a hierarchical view towardthephenomena.

Therefore, this study is built upon the studies related to spiritualityin tourismconducted through the fuzzy logicmethodologies. According to the obtainedresults, this important approach must be paid attention so that the great capacities of spirituality in tourism in the areas of knowledge and action can be correctly utilized.

In the next step, in order to ensure the factor structure and validity of the structures, and to fit the model using the field method and distribution of questionnaires, a survey of senior managers of small and medium companies in Tehran was conducted. The sample size was determined using the sample size method required for modeling structural equations, 200 people, and finally 162 questionnaires were selected using a simple random method.
