Show at least one metaphysical account of reality

For example, you might discuss Plato, Aristotle, or the Cartesian method. Make sure that you include an account of reality and truth and discuss how (and/or whether) human beings are capable of knowing reality with any certainty. For instance, is there a difference between a well-founded opinion and a false one? How are opinions/beliefs related to the truth as such?

Identify and explain an additional metaphysical theory that would take a different approach
