Avicenna

“All that is gold does not glitter,
Not all those who wander are lost;
The old that is strong does not wither,
Deep roots are not reached by the frost.

From the ashes a fire shall be woken,
A light from the shadows shall spring;
Renewed shall be blade that was broken,
The crownless again shall be king.”
― J.R.R. Tolkien, The Fellowship of the Ring

“Two things are infinite: the universe and human stupidity; and I'm not sure about the universe.”
― Albert Einstein

“Whenever you find yourself on the side of the majority, it is time to reform (or pause and reflect).”
― Mark Twain

“The fool doth think he is wise, but the wise man knows himself to be a fool.”
― William Shakespeare, As You Like It
