People used to read chiefly for knowledge or to pursue lines of thought. There wasn't so much fiction as now. These proportions have changed. We read some books to feed our curiosity but more to feed our emotions. In other words, we moderns are substituting reading for living.
When our ancestors felt restless they burst out of their poor bookless homes, and roamed around looking for adventure. We read some one else's. The only adventures they could find were often unsatisfactory, and the people they met in the course of them were hard to put up with. We can choose just the people and adventures we like in our books. But our ancestors got real emotions, where we live on canned.
