Diogenes was a famous Greek philosopher, known as one of the founders of Cynicism. Banished from his native country and without any resource, Diogenes was reduced to great indigence. He perceived one day, a mouse running briskly up and down, without any fear of being surprised by the approach of night, without any anxiety about a lodging-place, and even without thinking of food. This reconciled him to his misery. He resolved to live at his ease, without constraint, and to dispense with everything which was not absolutely necessary for the preservation of life.
