Ivanka showed you the mechanism of
Platons Cave Allegory he published in his famous book Politea.
You are prisoner in a dark cave with only one illuminated wall inside.
Light falls from outside on this wall. Now, whoever projects a shadow play onto this: he will make your reality like 100 percent.
In modern philosphy, (radical) constructivism uses Platon oftenly with this as an introduction, but also Immanuel Kant w/: space & time are categories of perception.
There are also a language based approaches like Locke, Descartes, Husserl, Merleau-Ponty or Douglas-Hofstadter or Minsky. (leave out Wittgenstein here, he made up a boring catalog only)
It is also about fuck empirism btw. Don't know, the english term may ba epistemology? English is too simplified for me as i'm used to think in german. #Erkenntnistheorie #Konstruktivismus
With htis, Ivankas shadow play may teach you about the nature of your perceived "reality". Meditation is able to transcend btw, that is why Yoga and Zen are so important.
