Paradoxically, Nicolas used the example of the unicorn to emphasize the importance of direct observation over purely bookish information. The creature would disparage “les gens de cabinet” who didn’t believe in unicorns simply because they had never travelled outside their parish. As he wrote in the The Natural History of the New World (Histoire naturelle des Indes occidentales): 
 

“I do not know what to say about the appalling error that has crept in even among many learned people who are otherwise very knowledgeable, but have seen nothing of the admirable things produced by nature because they have never lost sight of their parish church tower, and who hardly know how to get to the Place Maubert or the Place Royale without asking the way. I say that these people are stubborn to insist that there is no unicorn anywhere in the world.”
