While Chesterton has been tagged as being the Apostle of Common Sense, I would add also a the Apostle of Gratitude and Thanksgiving. Nothing makes me see the actual wonder of our lives as much as GKC does.
“I would maintain that thanks are the highest form of thought, and that gratitude is happiness doubled by wonder.” (A Short History of England » Ch. 6: The Age of the Crusades)
“When we were children we were grateful to those who filled our stockings at Christmas time. Why are we not grateful to God for filling our stockings with legs?”
This one described much of my life as an atheist to a T (there is a Tau joke in there no doubt).
“The worst moment for an atheist is when he is really thankful and has no one to thank.”
“You say grace before meals. All right. But I say grace before the concert and the opera, and grace before the play and pantomime, and grace before I open a book, and grace before sketching, painting, swimming, fencing, boxing, walking, playing, dancing and grace before I dip the pen in the ink.” (early notebook, mid 1890s)
And lastly:
“The Americans have established a Thanksgiving Day to celebrate the fact that the Pilgrim Fathers reached America. The English might very well establish another Thanksgiving Day to celebrate the happy fact that the Pilgrim Fathers left England.” (Chesterton in America “And What about the Quakers?”)
