Early man lived on the strength of his muscle power. The destinies of nations were shaped by wars. Later on man realized that the use of weapons could kill a man but could not bring about a change of heart. Ideas have a much larger impact than violence. Ideas are propagated by writing. Writings have helped man to store and propagate his thoughts, beliefs and ideas. The pen has been able to make the people standup against tyranny and injustice. Good literature survives the test of time. The pen stands for positive and constructive efforts. It can plead for progress and social reform. It promotes cultural values. Wars, on the other hand, tend to destroy civilization. It is the power of pen that has, through the ages, shaped human history.
