Is 'faith' really a 'great cop-out'?

[CoxRox]

I ask this as I just noticed a quote of Richard Dawkins. I would love to be able to proove things for myself e.g E=mc2. (I am rubbish at even basic maths and know that I can't fathom equations like this but I have faith that others understand and know the workings of them.) I don't think faith need always be negative as Dawkins asserts. Yes, it can mean you have blindly accepted something without trying to understand it, (which would make you a fool) but it can also be because you are not capable of understanding the whole picture but you understand and 'see' how other related stuff works.
