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 laughter is a uniquely human phenomenon born out of our ability to experience deep suffering. The implication is that humans suffer to such an extent that laughter becomes necessary as a coping mechanism to alleviate pain. It proposes that laughter is a response to the intensity of our suffering, and it distinguishes humans from other species as the only ones who possess this form of release.
