you must remember, just beginning love-letters to Nettie.

We live now in these days, when the Great Change has been in most
things accomplished, in a time when every one is being educated to a
sort of intellectual gentleness, a gentleness that abates nothing
from our vigor, and it is hard to understand the stifled and
struggling manner in which my generation of common young men did
its thinking. To think at all about certain questions was an act
of rebellion that set one oscillating between the furtive and the
defiant. People begin to find Shelley--for all his melody--noisy
and ill conditioned now because his Anarchs have vanished, yet there
was a time when novel thought HAD to go to that tune of breaking
glass. It becomes a little difficult to imagine the yeasty state
of mind, the disposition to shout and say, "Yah!" at constituted
authority, to sustain a persistent note of provocation such as we
raw youngsters displayed. I began to read with avidity such writing
as Carlyle, Browning, and Heine have left for the perplexity
of posterity, and not only to read and admire but to imitate. My
letters to Nettie, after one or two genuinely intended displays of
perfervid tenderness, broke out toward theology, sociology, and the
cosmos in turgid and startling expressions. No doubt they puzzled
her extremely.

I retain the keenest sympathy and something inexplicably near to
envy for my own departed youth, but I should find it difficult to
maintain my case against any one who would condemn me altogether as
having been a very silly, posturing, emotional hobbledehoy indeed
and quite like my faded photograph. And when I try to recall what
exactly must have been the quality and tenor of my more sustained
efforts to write memorably to my sweetheart, I confess I shiver. . .
