Knowing is not enough; we must apply. Willing is not enough;... - Johann Wolfgang von Goethe

"The world is so empty if one thinks only of mountains, rivers & cities; but to know someone who thinks & feels with us, & who, though distant, is close to us in spirit, this makes the earth for us an inhabited garden."

"All truly wise thoughts have been thought already thousands of times; but to make them truly ours, we must think them over again honestly, until they take root in our personal experience."

"The mediator of the inexpressible is the work of art."

"Man is not born to solve the problem of the universe, but to find out what he has to do; and to restrain himself within the limits of his comprehension."

"By seeking and blundering we learn."
