Could an illiterate farmer be more knowledgeable than a Nobel Laureate?

We, the healthy human beings often ignore thinking of the consequences for being physically or mentally disabled at the very beginning or at a later stage of our lives. Even we do not usually like to think one day (sooner or later) we will die. This is because nobody in general likes to embrace any sort of disability or death. We may consider it advantageous in terms of having a happy or smooth life without receiving that unnecessary stress. But, by doing so, we may be ignoring to understand the purpose of our lives in this world. Should we not be more vigilant in deciphering the numerous signs encircling us? Institutional education is quite helpful, but not essential in understanding the signs. In other words, an illiterate farmer could be more knowledgeable than a Nobel Laureate in that context.
