“When taking Spock to see the spores, Leila comments, "It's not much further." having been beaten about the head severely on the difference between "further" and "farther," I believe I can say with some trembling confidence that she should say, "it's not much farther."

“Social progress: for the same price as last year, I get a slimmer candy bar, less chips per bag, and I have to walk a little further to work, because to spend the same amount on gas I have to continuously park farther and farther away from the building.”

“I didn't go to the moon, I went much further—for time is the longest distance between two places”

“But if we betray B., for whom we betrayed A., it does not necessarily follow that we have placated A. The life of a divorcée-painter did not in the least resemble the life of the parents she had betrayed. The first betrayal is irreparable. It calls forth a chain reaction of further betrayals, each of which takes us farther and farther away from the point of our original betrayal.”

“The further I get from the things that I care about, the less I care about how much further away I get.”
