सुभाषित सुधानिधि - मूर्ख

निर्धनश्चापि कामार्थी दरिद्रः कलहप्रियः |
मंदशास्त्रो विवादार्थी त्रिविधं मूर्खलक्षणम् ||

- सुभाषित सुधानिधि

There are three kinds of fools - one who has lot of desires in spite of being penniless, one who gets into fights (quarrels) in spite of being poor (and hence at a disadvantage), one who gets into a debate without having enough knowledge about the subject matter.
