Computers are great tools, but they need to be applied to the physical world.

However completely people might fulfil themselves in other spheres, if they don’t possess this understanding between their hands and material objects, they can never have more than an incomplete understanding of the world.

If we were all perfected beings, we wouldn't be here in the physical world.

I really believe that the virtual world mirrors the physical world.

Great faith overcomes laws of nature that govern physical world.
