There are, indeed, things that are inexpressible. They show themselves. They are what is mystical. - Ludwig Wittgenstein

I give no sources, because it is indifferent to me
whether what I have thought has already been
thought before me by another.

Man könnte sagen: „Genie ist Mut im Talent.

In order that a certain sentence should assert a certain fact there must, however the language may be constructed, be something in common between the structure of the sentence and the structure of the fact.
