There is no shame or harm in not knowing something. You should be ashamed and embarrassed when you pretend you know what you actually do not.
It is better not to read any books than to read many and believe them all. You can be a clever man without a single book, but if you believe all that is written in books, you can quickly become a fool.
L. Tolstoy
