Without a knowledge of the past, we would have no knowledge at all. Well..

yes i agree with that.. cause for you to be able to understand the present you must know your past.. then you will be able at least predict the future.

I agree. Based on the principal that history repeats itself, those who don't learn from history are doomed to repeat it. I completely agree with that statement. Plus, all the scientific break-throughs and advancements in technology couldn't have been made without pioneers, people who took the initiative to find answers in the first place. :-)

So true, yet the past also holds us back what with prejudice, racism, etc.
