How to Make Our Ideas Clear

Peirce asks: "How is true belief distinguished from false belief". (43) How do we know what is considered to be real and what is considered to be fake? There are many things in the world that look real but are far from real. They are in fact fake, however they manage to make their outside appearance look real. This tricks people and messes with their minds, not knowing what is real and what is fake. Therefore, it is hard to make our ideas of things clear without a pure definition of everything. Everyone has a different view and belief on things, that is opinion. Though if everyone thinks differently, how can we all agree on one thing? It is almost impossible. Some people may have similar ideas, other complete opposite, this is where people will get confused and not have a clear idea of things. So how is it possible to distinguish between true belief and false belief, if everyone has a different definition or idea for both?
