It is good to be reminded of why we read, why we think, why we take classes, why we read a good novel. Augustine is often a good one to turn our minds to the basics. For Augustine, we all want to be happy (maybe in another post we can try to push or challenge Augustine here. We shall see).
But, Augustine is on to something. He writes:
"Man has no reason to philosophize except with a view to happiness" (The City of God 19.1.3).
