My mind has changed during the last twenty or thirty years. Now for many years I cannot endure to read a line of poetry. I have also lost my taste for pictures or music. My mind seems to have become a machine for grinding general laws out of a large collection of facts.
If I had to live my life again, I would make a rule to read some poetry and listen to some music at least once a week. The loss of these is a loss of happiness.
