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.'

But the solution to the riddle of life and space and time lies outside space and time. For, as it should be abundantly clear by now, nothing inside a frame can state, or even ask, anything about that frame. The solution, then, is not the finding of an answer to the riddle of existence, but the realization that there is no riddle. This is the essence of the beautiful, almost Zen Buddhist closing sentences of the Tracticus: "For an answer which cannot be expressed the question too cannot be expressed. The riddle does not exist."

Radical constructivism, thus, is radical because it breaks with convention and develops a theory of knowledge in which knowledge does not reflect an 'objective' ontological reality.

You cannot not communicate. Every behavior is a kind of communication. Because behavior does not have a counterpart (there is no anti-behavior), it is not possible not to communicate.

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

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.

It is difficult to imagine how any behavior in the presence of another person can avoid being a communication of one's own view of the nature of one's relationship with that person and how it can fail to influence that person.
