Cover Quotes
All these soft kinds [of stone] have the advantage that they can be easily worked as soon as they have been taken from the quarries. Under cover, they play their part well; but in open and exposed situations the frost and rime make them crumble, and they go to pieces. On the seacoast, too, the salt eats away and dissolves them, nor can they stand great heat either.
Vitruvius
The goal of mankind is knowledge ... Now this knowledge is inherent in man. No knowledge comes from outside it is all inside. What we say a man 'knows', should, in strict psychological language, be what he 'discovers' or 'unveils' what man 'learns' is really what he discovers by taking the cover off his own soul, which is a mine of infinite knowledge.
Swami Vivekananda
