The explorer who will not come back or send back his ships to tell his tale is not an explorer, only an adventurer; and his sons are born in exile.
Ursula K. Le GuinAll 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 GuinThe important thing is not the finding, it is the seeking, it is the devotion with which one spins the wheel of prayer and scripture, discovering the truth little by little.
Ursula K. Le GuinThere was a wall. It did not look important. It was built of uncut rocks roughly mortared. An adult could look right over it, and even a child could climb it. Where it crossed the roadway, instead of having a gate it degenerated into mere geometry, a line, an idea of boundary. But the idea was real. It was important. For seven generations there had been nothing in the world more important than that wall. Like all walls it was ambiguous, two-faced. What was inside it and what was outside it depended upon which side of it you were on.
