Quote by Friedrich Nietzsche
Perhaps I know why it is man alone who laughs He alone suffers so deeply that he had to invent laughter.
Summary
This quote suggests that the ability to laugh is unique to human beings because they are capable of experiencing deep suffering. The invention of laughter is seen as a coping mechanism or a means of finding relief from the pain and struggles that humans face. While animals may feel pain, the quote implies that humans suffer to a greater extent, prompting them to create laughter as a response to their intense emotions.
