The glorious sun
Stays in his course, and plays the alchemist;
Turning with splendor of his precious eye,
The meager cloddy earth to glittering gold (sweet).

—King John: Shakespeare

From Nature’s magic hand whose touch makes sadness
Eventual gladness,
The reverent moral Alchemist may learn
The art to turn
Fate’s roughest, hardest, most forbidding dross,
Into the metal gold that knows not change or loss.

—Horace Smith

The world is always ready to receive talent with
open arms. Very often it does not know what to do
with genius. Talent is a docile creature. It bows
its head meekly while the world slips the collar
over it. It backs into the shafts like a lamb. It
draws its load cheerfully, and is patient of the
bit and of the whip. But genius is always impatient
of its harness; its wild blood makes it hard to
train. Talent is a very common family-trait;
genius belongs rather to individuals. Talent is
often to be envied, and genius very commonly to be
pitied. It is a perpetual insult to mediocrity; its
every word is a trespass against somebody’s vested
ideas.
