Although the accrual of knowledge is both dangerous and unprecedented, I believe that it is more important for us to aspire to step outside our self defined borders and accept the drawbacks than to sit back and be ignorant to the world around us.
Hi Shannon, this sentence above is quite chaotic. I think I know what you mean, but you have to really clarify it: Although the accrual of knowledge has produced catastrophic results (i.e. "weapons of mass destruction"), I believe that it also can be the key to avoiding further catastrophe in the future.
I think this is a little like what you are trying to say, right? I don't think you have to include the part about not wanting to "sit back and be ignorant"...
Overall, I really think this essay makes a good impression!
