Now, a symbol is not, properly speaking, either true or false; it is, rather, something more or less well selected to stand for the reality it represents, and pictures that reality in a more or less precise, or a more or less detailed manner.

When I am giving the relation of a thing, remember to abstain from altering either in the matter or manner of speaking, so much, as that, if every one, afterwards, should alter as much, it would at last come to be properly false.

 
Jonathan Edwards
 

The Western approach to reality is mostly through theory, and theory begins by denying reality — to talk about reality, to go around reality, to catch anything that attracts our sense-intellect and abstract it away from reality itself. Thus philosophy begins by saying that the outside world is not a basic fact, that its existence can be doubted and that every proposition in which the reality of the outside world is affirmed is not an evident proposition but one that needs to be divided, dissected and analyzed. It is to stand consciously aside and try to square a circle.

 
Bruce Lee
 

Stock market bubbles don't grow out of thin air. They have a solid basis in reality — but reality as distorted by a misconception. Under normal conditions misconceptions are self-correcting, and the markets tend toward some kind of equilibrium. Occasionally, a misconception is reinforced by a trend prevailing in reality, and that is when a boom-bust process gets under way. Eventually the gap between reality and its false interpretation becomes unsustainable, and the bubble bursts.

A child might be overawed by a great city, but a civil engineer knows that he might demolish it and rebuild it himself. Husserl's philosophy has the same aim: to show us that, although we may have been thrust into this world without a 'by your leave,' we are mistaken to assume that it exists independently of us. It is true that reality exists apart from us; but what we mistake for the world is actually a world constituted by us, selected from an infinitely complex reality.

 
Colin Wilson
 

The fact is that pictures which are unlike reality ought not be approved, and even if they are technically fine, this is no reason why they should offhand be judged to be correct, if their subject is lacking in the principles of reality carried out with no violations.
