knowledge is the awareness / perception / understanding of something

there are types of knowledge
for example, the knowledge of how to do things and the knowledge of something

it is required to form arguments

but what does it mean to have knowledge of something?

plato’s theory of knowledge states that you need to believe something, have justification / evidence to support your belief.
however, it is not a justified theory, and making it complete is harder than expected

the hardest part of knowledge is to justify it
