The course opens up the mind, particularly in the field of epistemology. It successfully made us wonder if knowledge can ever be defined. And, to delve further, it made us think whether there is any 'foundational' knowledge that does not have to be justified. But, since knowledge can be seen as a 'justified' belief, it makes us wonder whether those 'foundational' knowledge really is knowledge, or are the axioms in mathematics are just 'beliefs'.
Are the letters that form words just 'beliefs'? Quite absurd to call it a belief but does not match the definition of a 'knowledge' either.
