This is a quote by Friedrich Nietzsche, a German philosopher, and it refers to the idea that some people intentionally make things more complex or obscure than necessary to make themselves seem more intelligent or knowledgeable than they actually are.

In other words, the quote suggests that people might use confusing language or complicated explanations to create the illusion of expertise or depth of understanding, even if they don't actually have it. This can make it difficult for others to discern what is actually important or relevant, and can lead to misunderstandings or misinterpretations.

The quote can also be applied more broadly to situations where people deliberately obscure the truth or make things more complicated than necessary for their own gain or advantage. In these cases, it is important to be vigilant and to seek out clear and straightforward explanations, rather than being misled by those who seek to muddy the waters.
