That we do not discover reality but rather invent it is quite shocking for many people. And the shocking part about it - according to the concept of radical constructivism - is that the only thing we can ever know about the real reality (if it even exists) is what it is not. It is only with the collapse of our constructions of reality that we first discover that the world is not the way we imagine.

The belief that one's own view of reality is the only reality is the most dangerous of all delusions.

In other words, what is supposedly found is an invention whose inventor is unaware of his act of invention, who considers it as something that exists independently of him; the invention then becomes the basis of his world view and actions.

If we have dwelled on Godel's work at some length, is it because we see it in the mathematical analogy of what we would call the the ultimate paradox of man's existence. Man is ultimately subject and object of his quest. While the question whether the mind can be considered to be anything like a formalized system, as defined in the preceding paragraph, is probably unanswerable, his quest for an understanding of the meaning of his existence is an attempt at formalization.

As I have already said, the belief that one's own view of reality is the only reality is the most dangerous or all delusions. It becomes still more dangerous if it is coupled with the missionary zeal to enlighten the rest of the world, whether the rest of the world wishes to be enlightened or not. To refuse to embrace wholeheartedly a particular definition of reality, to dare to see the world differently can become a "think crime" in a truly Orwellian sense as we get steadily closer to 1984.

Maturity… is the ability to do something even though your parents have recommended it.

A self-fulfilling prophecy is an assumption or prediction that, purely as a result of having been made, cause the expected or predicted event to occur and thus confirms its own 'accuracy.'
