The universe is built on a plan 

the profound symmetry of which 

is somehow present 

in the inner structure of our intellect.

Art is the symbol of the two noblest human efforts: 

to construct and to refrain from destruction.

There are some people 

who live in a dream world, 

and there are some 

who face reality; 

and then there are those 

who turn one into the other.

Everything you can imagine is real.

You're only as young as the last time you changed your mind.

Genius is the recovery of childhood at will.

Think like a man of action, 

act like a man of thought.

No better way is there 

to learn to love Nature 

than to understand Art. 

It dignifies every flower of the field.

Love is blind; 

friendship closes its eyes.

The world is mud-luscious and puddle-wonderful.

One is and is not in the centre of the mælstrom of it all.

Going after the unknown 

is always fascinating, I think. 

It becomes part of your life, 

this desire to know.

The home should be the treasure chest of living.

Knowledge is the most democratic source of power.

Accuracy of observation is the equivalent of accuracy of thinking.

Heresy is another word for freedom of thought.
