I remember a passage in Goldsmith's "Vicar of Wakefield," which he was afterwards fool enough to expunge: "I do not love a man who is zealous for nothing."… There was another fine passage too which he struck out: "When I was a young man, being anxious to distinguish myself, I was perpetually starting new propositions. But I soon gave this over; for I found that generally what was new was false."
