Why should we know history?

He raised his hand. Someone passed him the mic. Now we could all hear him loud and clear. "Why do so many people know about the massacre of Jews by the Nazi Germany and only few know about Japan's atrocities in China during the Japan-China war?", he asked her.

She answered with a question. "Why do so few people know about history? Why is history not taught in school any more?"

The crowd seemed to agree. Many shook heads disapproving the current wide-spread ignorance towards history.

But, how has the knowledge of history helped us along the way. Having the experience of two world wars, two nuclear bombs explosions, apartheid, and the cold war has not made the world a more peaceful, more secure, more accepting and respectful of differences.

The past has not taught us anything. Many of the today's problems are residues of old unresolved, grudges.

I propose :) we forget about learning and teaching the history since thus far this knowledge has not brought us happiness.
