Reading for pleasure
From T. S. Eliot:
I incline to come to the alarming conclusion that it is just the literature that we read for ‘amusement’, or ‘purely for pleasure’ that may have the greatest and least suspected influence upon us. It is the literature which we read with the least effort that can have the easiest and most insidious influence upon us. Hence it is that the influence of popular novelists, and of popular plays of contemporary life, requires to be scrutinized most closely.
