Research on values is extensive. Values and value systems are concepts that have interested researchers across domains such as psychology, sociology, and anthropology. However, antecedents of values have not received sufficient attention. In this study, we develop and assess a personal value system from the ancient texts of India. The texts describe a system of existential beliefs and values or prescriptive beliefs. Existential beliefs are concerned with the nature of reality. Prescriptive beliefs or values follow from these existential beliefs, and (...) behavior is influenced by values. The content of existential beliefs and the implied values or prescriptive beliefs are extracted from the texts and a conceptual model of the belief system is developed. Scales are constructed and administered to a sample of subjects. Responses from the survey are analyzed using a structural equation modeling framework. Confirmatory factor analysis is used to assess the scales and establish their adequacy. The nomological net of existential beliefs and values is empirically assessed, and construct validity is examined. Results support the belief system described in the texts. (shrink)
