[W]e really ought to free ourselves from the misleading significance of words! For their part, people may think that cognition is knowing all about things, but the philosopher must say to himself: "When I analyze the process that is expressed in the sentence, 'I think,' I find a whole series of daring assertions, the argumentative proof of which would be difficult, perhaps impossible: for instance, that it is I who think, that there must necessarily be something that thinks, that thinking is an activity and operation on the part of a being who is thought of as a cause, that there is an 'ego,' and finally, that it is already determined what is to be designated by thinking—that I KNOW what thinking is.

Reflect on the passage by Friedrich Nietzsche above. What do you think he is saying? Why do you think it is difficult to understand what he is saying? In general, when we encounter new modes of thinking, is it difficult or easy to comprehend? Why do you think that is?
