Who can discern those planets that are oft combust, and those stars of brightest magnitude that rise and set with the sun, until the opposite motion of their orbs bring them to such a place in the firmament, where they may be seen evening or morning? The light which we have gained was given us, not to be ever staring on, but by it to discover onward things more remote from our knowledge. One thing alone is needful, the salvation of one's soul. --There's a crack of the whip left in me yet, Stephen, old chap, said Mr Dedalus, poking at the dull fire with fierce energy.
