You have been taught to think in such a way that you will be unable to find the truth. The fruitful and effective type of hypothesizing developed by Plato and the Renaissance, has been largely replaced with the notion that, ultimately, knowledge comes from the senses. Did you ever see a “justice”? Did you ever smell “equality” or hear “beauty” itself? Did you ever taste a “gravitation”? Today, we will take up the “complex domain” of science and of politics: the existence of truly existing principles that are invisible to the senses, and how to discover and use them.
