Here is a quote I recently pulled off of Slashdot:

History is curious stuff You’d think by now we had enough Yet the fact remains I fear They make more of it every year.

This got me to thinking of another quote:

Those who do not learn from history are doomed to repeat it.

Which made me think:

We as humans certainly have more than enough history to enable us to never make another mistake again if we’d only learn to draw on the history we already have.

Sadly however, a final quote comes to mind:

History teaches us that history teaches us nothing.
