Besides beauty what else gives us a sense of preasure. Also give the theme of poem, "A thing of beauty"
The poem does not mention specifically as to what gives a sense of pleasure besides beauty. The source of pleasure may vary from person to person.
Keats argues in the poem that a beautiful thing is a source of eternal joy and the beauty actually lies in the eyes of beholder. There are many beautiful things in the nature like the sun, the moon, the flowers, the serene river flowing amid the valley, etc. Also, one can find beauty in the death of martyrs who died for the sake of nation. In a way, everything in the world around us has a beauty of it own. It rests with the person who perceives whether he is able to see its beauty or not.
