>you will literally never be able to read all the books you'd want to, and your knowledge will always be close to nothing
The sector of human understanding you can explore and grasp within a lifetime is tiny. You'd have to limit yourself to a minuscule part of a discipline, like, for example, the thoughts of a single philosopher, and study it like an autist for your whole life to gain a true insight into it. Even if you read a book a day, that would only be 365 books year. 365 times, say, 65 is less than 24 000 books, and I doubt anyone can realistically read that amount in their lifetime. Even if someone did, there would still be a 100 000 worthwhile books the person hasn't read, and his understanding of the world and human thought will always be quite small, objectively speaking.
And me? On average, I read maybe a book a week. With this rate, I can't necessarily even finish a total of 4000 books before I'm very old and maybe dead. Is less than 4000 books enough to truly understand the world? I fear not. I already know more about philosophy, psychology and theology than most people, and yet I know almost nothing. I'm afraid that I will never be able to flee the horrible, agonising feeling of mediocrity and ignorance.
Do you know this feel?
