Knowledge once gained casts a faint light beyond its own immediate boundaries.

On the Methods and Tendencies of Physical Investigation, p. 7John Tyndall
For a breeze of morning moves,
And the planet of Love is on high,
Beginning to faint in the light that she loves
On a bed of daffodil sky,
To faint in the light of the sun she loves,
To faint in his light, and to die.Alfred (Lord) Tennyson
The body which is nearest to the light casts the largest shadow, and why? If an object placed in front of a single light is very close to it you will see that it casts a very large shadow on the opposite wall, and the farther you remove the object from the light the smaller will the image of the shadow become.
Leonardo da Vinci
The ordinary man casts a shadow. In a way we do not quite understand, the man of genius casts light. Instinctively, we flinch from this light. We assure ourselves that genius must pay a terrible price. Often history bears us out: the creator, the supreme artist, the master of politics carries the scars of his greatness.
George Steiner
Philosophical knowledge is the knowledge gained by reason from concepts; mathematical knowledge is the knowledge gained by reason from the construction of concepts.
Immanuel Kant
A prison taint was on everything there. The imprisoned air, the imprisoned light, the imprisoned damps, the imprisoned men, were all deteriorated by confinement. As the captive men were faded and haggard, so the iron was rusty, the stone was slimy, the wood was rotten, the air was faint, the light was dim. Like a well, like a vault, like a tomb, the prison had no knowledge of the brightness outside; and would have kept its polluted atmosphere intact, in one of the spice islands of the Indian Ocean.
