History is the memory of mankind and philosophy of history is the analytical ability of man to distinguish correct from incorrect. Intelligence is the sum of memory and ability to distinguish hence history and philosophy of history constitutes the collective intelligence of mankind. Philosophy of history helps us to know the reasons for the rise and fall of nations.

If we trace back the reasons for the rise of nation they converge to only one reason as do the reasons of downfall and that sole reason is usefulness. The nation which is useful for the mankind rises to the skies of excellence and the nation which is a liability instead of an asset to humanity withers away from the pages of history as if it never existed at all. Only the nation that contributes to the collective evolution, progress and development of mankind rises. This indirectly is the surety for the survival of a nation which otherwise is threatened by the laws of nature all the times.

The fastest way to become useful to mankind is by focusing on the creative potential present in the human resource of a nation. The product of creativity is idea. Idea is an asset. Asset is the raw material for technology. Technology is the key to progress. Progress is the road to glory. Sharing the fruits of glory makes a nation beneficial to humanity and gives it the guarantee for survival. If nation with glory does not share the fruits of its glory and achievements with the rest of the mankind then its decline is unavoidable.

Explore the world and you will come to know why the undeveloped nations are responsible themselves for their backwardness and why the developed nations deserve the position they have reached. The reason is usefulness.

It is very easy to say that undeveloped countries have exploitative governments but who chooses these governments? If the governments are dictatorial then why the masses do not resent and resist the dictatorship? If there is democracy but still the system is not based on social justice then why the masses do not raise their voice against the system? How do you expect any positive change which is always the result and output of human effort without actually contributing your part of input? It is very easy to put the blame on others but very difficult to confess one's own limitations and try to remove them.

What is seen at the top is nothing but the output of a nation's collective input. If there is something wrong at the top there must be something wrong at the bottom. If you sow seeds of cactus then do not expect its fruit to be mango.

A group of people becomes a nation if they have common language or common ancestry or common territory. The following points are worth mentioning regarding the extinction or glory of a nation.

1. If the people of a nation have common ideology of life then their efforts will be fruitful.

2. If the ideology of a nation is in synchronism with the laws of nature then the nation will achieve excellence.

3. If the collective input of a nation is in accordance with the laws of collective behavior then their efforts (input) will be in synchronism with the laws of nature.

4. If the input of a nation is in synchronism with the laws of nature then the nation will achieve their target.

5. If the target of a nation is in accordance with the laws of nature then the nation will achieve excellence.

6. If the target of a nation is not in accordance with the laws of nature then the efforts of a nation become futile and only adds to their experience if in the meanwhile it is not attacked militarily, intellectually or technologically by other nations.

History glorifies a nation if:

1) The collective behavior of a nation is in synchronism with the direction of history and they have a clear vision to achieve its collective targets.

2) The nation has better ideology capable of attracting humanity due to their views about progress and prosperity of mankind and evolution of humanity.

3) The nation has an urge for exploration, expedition, creation, innovation, research, development and opening new vistas of knowledge and probability.

4) The nation has been leading their lives according to certain cultural values for centuries due to which their culture and language has been enriched with experiences and wisdom.

5) The nation has an affinity for their language, race, territory, culture, traditions and civilization.

Nature always favors that nation which promotes its cause. The cause of nature is the progress of humanity to achieve excellence. It is only by striving to rise to the skies of excellence that a nation can justify its existence which otherwise is always threatened by the rude and crude forces of nature. The nation which strives to achieve excellence is in synchronism with the direction of history and the scheme of universal evolution and forces of the universe align them in its direction giving a quantum jump to its struggle and paving the way for its glory. Any nation which does not strive to achieve excellence is indirectly offering open invitation to other nations to attack, conquer, exploit and perish it from the surface of earth.
