There's a scene towards the end of Ubik by Philip K. Dick*, in which the hero, Joe, is dying on a staircase.
'Feel any better?' Pat asked.
'No,' he said. And, getting halfway up, lunged onto the next step.
'You look different. Not so upset.'
Joe said, 'Because I can make it. I know that.'
'It's not much further,' Pat agreed.
'Farther,' he corrected.
'You're incredible. So trivial, so small. Even in your own death spasms you-' She corrected herself, catlike and clever. 'Or what probably seem subjectively to you as death spasms. I shouldn't have used the term "death spasms." It might depress you.'
Just so you know, dear and careful reader, farther is generally used for physical distance and further for metaphorical distance. If you are curious about the city beyond the mountains you must travel farther to investigate further.
Onward and upward
*Just read it. Terribly good fun. And, weirdly, this post isn't really a spoiler.
