"<p>Every achievement of the so-called progress is accompanied by certain losses: for example, society is enriched by an invention, but at the same time a characteristic that is born with all of us is lost. The educated man has a swing, but he can hardly use his legs anymore. He has a great Geneva clock, but he gets an astronomical calendar because he trusts that he can find everything he needs to know in the book, he doesn't recognize a single star in the sky, and he doesn't notice either the spring or autumn equinoxes. A sensible person rejects all trivial things and always returns in the end to what he needs most.</p>"
