"Man lives in a world of surmise, of mystery, of uncertainties"

In this quote, John Dewey is revealing the idea that people exist in a truth that has lots of ambiguity, unpredictability and unanswered questions. Rather of possessing complete understanding and understanding of the world around us, we are continuously making assumptions and guesses about what is occurring and why things are the way they are. This quote recommends that a sense of mystery and confusion is a specifying characteristic of the human experience.
