Plato's "cave allegory" gives us a story of people who are born in darkness (ignorance), and seem to prefer that state to enlightenment (knowledge, education). He also notes that bringers of "light" (new ideas, the unfamiliar) are often unwelcome, and receive a hostile reception.
Briefly (150-250 words) discuss any case in history, or perhaps from your own experience, in which someone bringing the "light" of knowledge (a new idea, a new way of thinking, new information) was rejected, only to be proved correct later. Feel free to use the Internet to do a little research for this if you need to.
