Q The rejection of the parallel line axiom raised doubts about our basic sense of reason. If parallel lines can meet -- as the mini-lecture discussion shows -- then what's left? The Evil Demon Argument raised doubts about tradition, authority and religion; the Dream Argument questioned human experience and science; the rejection of the parallel line axiom raised doubts about reason itself. Are there no certainties? We live in an era (at least in the Western world) where nothing is sacred. What do you rely on to confirm your own opinions? Can you justify your choice given the discussion thus far?

A condition of absence of certainties or presence of uncertainties is not an uncommon phenomenon. It permeates a lot of aspect of our everyday life. In the common parlance, the nation of uncertainty might invoke a sense of mystery and vagueness, a fuzzy terrain to tread upon. However, in scientific terms, uncertainty refers to the extent to which knowledge about something is established. Since humans are fallible and are engaged in a continuous process of acquiring knowledge, uncertainty rather certainty becomes the norm.
