The Creator, who designed the human brain for activity, had insured the restlessness of all minds by enabling no single one to envisage all the qualities of the creation. Since no one by himself could aspire to a serene knowledge of the whole truth, all men had been drawn into an active, exploratory and cooperative attitude.
