Potential For Intelligence

“Indeed, human life begins when religion begins. Eating, sleeping, fearing, and mating are the four principles of animal life. These are common both to animals and to human beings. But religion is the extra function of the human being. Without religion, human life is no better than animal life.” (Shrila Prabhupada, Shrimad Bhagavatam, 1.1.2 Purport)
