All knowledge is partial, infinitesimally partial. Reason is a net thrown out into an ocean. What truth it brings in is a fragment, a glimpse, a scintillation of the whole truth.
Ursula K. Le GuinNow they came back to him, on this night he was seventeen years old. All the years and places of his brief broken life came within mind's reach and made a whole again. He knew once more, at last, after this long, bitter, waisted time, who he was and where he was. But where he must go in the years to come, that he could not see; and he feared to see it.
