"Since his life had been caught up into the current of this great stream, things which had before been the whole of life to him came to seem of relatively slight importance; his interests were elsewhere, in the world of ideas. His outward life was commonplace and uninteresting; he was just a hotel-porter, and expected to remain one while he lived; but meantime, in the realm of thought, his life was a perpetual adventure. There was so much to know—so many wonders to be discovered!"
Upton Sinclair
