The notion of stubborn incuriosity.....

To cultivate a stubborn incuriosity, you have to limit yourself to certain areas of knowledge. You cannot be totally greedy. You have to oblige yourself not to learn everything. Or else you will learn nothing. Culture in this sense is about knowing how to forget. Otherwise, one indeed becomes like Funes, who remembers all the leaves of the tree he saw thirty years ago. Discriminating what you want to learn and remember is critical from a cognitive standpoint.
