You are a restless seeker, a Philosophy-Junkie. And you want to know all about ‘Know’. You want to know what ‘Knowledge’ means.
Not to worry. There is such a subject. And it is called Epistemology. You’ve come to the right department.
Epistemology is the scholarly study of ‘Knowing’ while firmly resident in the Know. It is knowing all about ‘Knowing’ and ‘Knowledge’. [Can you smell the Self-Loop yet?]
Empistemology [‘Know’] and Ontology [‘Be’] are the twin foundations of Philosophy. Any grand discourse on Philosophy without a clear investigated statement about these two stances is not worth the paper it is written on. The first is covered here; we leave the second, Ontology, for the Posts.
