The only thing worse than being blind is having sight and no vision. - Helen Keller

They took away what should have been my eyes (but I remembered Milton's Paradise).

For, after all, every one who wishes to gain true knowledge must climb the Hill Difficulty alone, and since there is no royal road to the summit, I must zigzag it in my own way. I slip back many times, I fall, I stand still, I run against the edge of hidden obstacles, I lose my temper and find it again and keep it better, I trudge on, I gain a little, I feel encouraged, I get more eager and climb higher and begin to see the widening horizon. Every struggle is a victory. One more effort and I reach the luminous cloud, the blue depths of the sky, the uplands of my desire.

The bulk of the world's knowledge is an imaginary construction. History is but a mode of imagining, of making us see civilizations that no longer appear upon the earth. Some of the most significant discoveries in modern science owe their origin to the imagination of men who had neither accurate knowledge nor exact instruments to demonstrate their beliefs. If astronomy had not kept always in advance of the telescope, no one would ever have thought a telescope worth making. What great invention has not existed in the inventor's mind long before he gave it tangible shape?
