"What is Man" consist of series of dialogues between an elderly with a strong sense of humour and a young impatient man.
Throughout the book, the author compares humans to machines. He argues that man has no impulse other than the pursuit of pleasure and the avoidance of pain.
The book is a great starter for those who are seeking to understand why many of us have lost the meaning of life. This work questions how our personal values and the environment surrounding us shape our identity.
Although written in 1906, today the dialogues still shed light on how people can take actions with their own free will.
