“True learning must not be content with ideas, which are, in fact, signs, but must discover things in their individual truth.”

Simplified Meaning:

To really learn something, it's not enough to just know facts or ideas. You have to understand the actual reality behind them. Think about learning to ride a bicycle. You can read a book about it, understand where the pedals are, and know where the brakes are. But you truly learn by getting on the bike, feeling how it moves, and balancing yourself. In another example, consider history lessons. Reading about a historical event is just the start. To grasp what really happened, you need to know why people acted the way they did and what the consequences were. Maybe you even visit places where events occurred to see for yourself. So, in everyday life, to really understand something, you need to look deeper and experience it for yourself. Don't just stop at surface knowledge.
