Sounds like he doesn't think he knows everything, rather he thinks that science is capable of eventually explaining everything. Personally, I think the human race will die out before we are able to explain everything, but I agree with his sentiments. The human mind is capable of great understanding.
It is my belief that there is a Higher Power out there. I believe that we are here on this world and in this life as a test. A test of the Soul. One which will determine whether or not that Soul is prepared to move on to bigger and better things, be reeducated and try again, or be permanently found defective and tossed away into the scrap heap. Science is simply one of the many red herrings placed in our way to offer us an opportunity to step off the path of Right and trip us up, thus condemning our Soul to at least one more trip through life, or an eternal existance on the scrap heap.
That's amazing considering that you benefit greatly from the science you loathe. In fact, you're making great use of science right now in telling me how false science is.
Scientists and most of the organized religious community.
