This being the case, it is the duty of philosophy to describe their form, the way they are a part of reality. You demand an explanation of why reality can be the way it is. We are in a contradiction, a contradiction in language and thus reality. Philosophy simply puts everything before us, and neither explains nor deduces anything. The problems are solved, not by giving new information, but by arranging what we have always known.
Philosophy is a battle against the bewitchment of our intelligence by means of language.
Then something about the form of reality must allow for our contradiction to exist. If we intend to describe reality, we must resist the temptation to eliminate a contradiction. Instead we must look at how our understanding of the language in which the paradox is embedded makes it possible. The fundamental fact here is that when we lay down rules, a technique, for a game, and that then when we follow the rules, things do not turn out as we had assumed. We are therefore, as it were, entangled in our own rules.
