“There are two very clear indications of real science and real art: the first inner sign is that a scholar or an artist works not for profit, but for sacrifice, for his calling; the second, outer sign is that his works are understandable to all people. Real science studies and makes accessible that knowledge which people at that period of history think important, and real art transfers this truth from the domain of knowledge to the domain of feelings.”

Leo Tolstoy, A Calendar of Wisdom (Page 196)
