Even though I didn’t care much overall for The Name of the Rose, it was filled with little golden nuggets of wisdom.
If you can’t read my handwriting, this says: “Books are not made to be believed, but to be subjected to inquiry. When we consider a book, we mustn’t ask ourselves what it says, but what it means.”
In other words, don’t just take everything you read at face value. Question everything. Research further. Investigate.
Nothing written can ever be truly objective. Humans write this stuff, remember? And humans have opinions and bias. They also cannot see everything. Try to find out for yourself what the world around you looks like.
