Jean de la Bruyère.jpg

“A man may have intelligence enough to excel in a particular thing and lecture on it, and yet not have sense enough to know he ought to be silent on some other subject of which he has but a slight knowledge; if such an illustrious man ventures beyond the bounds of his capacity, he loses his way and talks like a fool.”           

–Jean de la Bruyère (French Essayist and Moralist, 1645-1696)
