Our orders are delivered strictly on time without delay 
Describe the theory of knowledge called skepticism. Consider the skeptic’s charge that we can never be
confident about the reliability of our normal sources of knowledge (perceptions, memory, introspection, and
reasoning.) Describe why and how, for each of the 4 sources mentioned, the source is unreliable. Use
examples to show your understanding.
If a source of knowledge is unreliable, it means these sources can trick us into believing falsehoods. Does it
follow from the fact that we are sometimes mistaken when we rely on these sources that we are always
mistaken? In other words, once we admit is possible that we are mistaken, does that mean that we need to
admit that we might never be correct? How would you respond to the skeptic?
