When we play tennis not only we are interacting with the reality, we are assuming that the reality will behave in a certain way. I doubt I will get very far by just contemplating the nature of the ball, the court surface, or the springiness of the string gut. But rather by interacting with the reality, I prove my understanding of it.
Knowing the limitation of my movement, my opponent’s, the way the ball behaves against the racket strings and court surface, the way the ball travels through the air with spin, I try to defeat my opponent. My performance is proof of this understanding.

In some ways Donald Trump’s actions are also proof of his understanding of the world. He uses it to “deceive” not only others but himself as well. I do not mean he is a bad person, but that is doing what we as humans do best – to achieve the most with what we have. So know ing what to do as a human, a cat, a religion is really proof. To me, this is a kind of (my kind of) objectivity.
