Plato's problem is the term given by Noam Chomsky to "the problem of explaining how we can know so much" given our limited experience.
In the field of linguistics, Plato's problem is the problem of finding an explanation for how a child acquires language, even though the child does not receive explicit instruction and the primary linguistic data a child does receive is limited.
What is the opposite of this problem, and who asked for it?
I.e., "the problem of explaining how we know so little given the proliferation of information in the modern world!"
