In life, everything has its meaning of existence and its task, which other things can't completely complete. For example, it is impossible for a person to experience life through other substitutes. It's the same whether you know the world or study. People try to lock their lives in books, just like locking songbirds in birdcages, but this is impossible. On the contrary, people just build a cage for themselves with the abstract concepts of books. Philosophers just wear different cages and strange parrots.
