Science cannot, however, guide us in the use of such knowledge. The revelation of God offers to humanity a basis for values and purpose. It provides answers to those questions of morals, human purpose, and our relationship to God that science cannot approach. The independent investigation of reality, whether scientific or religious, is strongly encouraged in Bah 'u'll h's writings. Individuals should strive, He said, to free themselves from prejudices, preconceptions and reliance on tradition or traditional authorities.
Consultation is a critical tool for discovering truth.
Bah 'u'll h also called for the adoption of a universal auxiliary language as a means to promote unity. When this is achieved, to whatsoever city a man may journey, it shall be as if he were entering his own home. Indeed, the Bah ' teachings both value and promote cultural diversity. When first outlined by Bah 'u'll h more than 100 years ago, these principles were as radical as any social program ever drafted. The fact that they have not only borne the passage of time, but, indeed, become ever more widely proclaimed and recognized is a testimony to the vision that produced them.
