Voltaire (Francois Marie Arouet Voltaire) once said...
But nothing is more estimable than a physician who, having
studied nature from his youth, knows the properties of the human
body, the diseases which assail it, the remedies which will
benefit it, exercises his art with caution, and pays equal
attention to the rich and the poor.
