"Remember also that it is not knowledge but the yearning for knowledge that makes for a complete, accomplished man. Such a man does not stand still but perseveres in the face of adversity, nor does he remain untouched by the pain cause by absence. On the contrary, he recognizes himself in each cry, uttered or repressed, in the smallest rift, in the most pressing need."

And in truth (as I now see) I had the wish to put off my journey as long as I could. Not for any peril or labour it might cost; but because I could see nothing in the whole world for me to do once it was accomplished. AS long as this act lay before me, there was, as it were, some barrier between me and the dead desert which the rest of my life must be.
